How to fix Your Open Live Writer Account Settings for

Fri, 07 Oct 2016 17:51:47 GMT

When I tried to post on my blog ( yesterday using Open Live Writer, it failed with an error message – I ended up posting via the web interface.

I contacted the ASP.NET website support and today Terri Morton got back to me, telling me that an update of the website last week forces https and that I should point my blog account to Interestingly, it was already set to https.

Adding a new account in Open Live Writer is really easy, so I tried that, but it didn’t work. Looking at the error message, a mix of https and http URIs caught my eye:


Digging in the registry, I found the following entry

      • OpenLiveWriter
        • Weblogs
            • PostApiURl =

After changing the URL from http to https and restarting Open Live Writer, my blog account worked again – this post is living proof.

UWP Community Toolkit 1.1 Released

Thu, 06 Oct 2016 20:28:25 GMT

Back in August I blogged about How to Search Twitter from Your UWP App using the then-new UWP Community Toolkit. Of course, the toolkit offers much more than that. It has now been updated to version 1.1, with quite a list of improvements and fixes. A small, but nice addition is the GridSplitter, which was one of the first things I was missing when moving from WPF to UWP.

The release also sends a strong signal about the future of the UWP Community Toolkit. It is now part of the .NET Foundation (which brings a move of the documentation to a new location) and has promising community activity. While this may not be a guarantee for longevity, at least the signs point into the right direction.

How to Disable Warnings in Generated C# Files of UWP Apps

Sun, 25 Sep 2016 23:08:00 GMT

The first time I moved my UWP development beyond writing “throwaway code for learning purposes”, I did what I always do when starting a new “real” project: On the “Build” tab of the project properties, I switched the setting “Treat warnings as errors” to “All” and set the checkmark at “XML documentation file”.

Nasty surprise: When compiling the UWP app, the compiler stumbled over missing XML doc comments in code that was generated in the background.

Fortunately, I quickly found a solution on StackOverflow that automatically added a #pragma warning disabled to the generated files using MSBuild. That worked well for me until recently, when I created a new solution configuration that had a name containing spaces. Digging a bit into MSBuild, and with the help of another StackOverflow answer, I was able to figure out the following build target (which I’ll add as an answer to the original StackOverflow question):


How to use this:

  • Unload and edit your “.csproj” file in Visual Studio (or open it in Notepad if Visual Studio is closed)
  • Copy-and-paste the task just before the closing tag
  • Save and (re)open in Visual Studio

How to Search Twitter from Your UWP App

Thu, 18 Aug 2016 11:05:00 GMT

Yesterday, the UWP Community Toolkit was released, “a new project that enables the developer community to collaborate and contribute new capabilities on top of the SDK.”. The toolkit “includes new capabilities (helper functions, custom controls and app services) that simplify or demonstrate common developer tasks”.


One thing that caught my eye was the support for social media like Twitter and Facebook. I had read the docs at and I had a twitter app configured at some months ago, but I never got around to actually choose a Twitter access library and use it.

But the few lines of sample code in the announcement (how to post a tweet) looked so simple I couldn’t resist trying to perform a Twitter search.

  • Follow the “Getting Started” instructions in the article. (I chose the packages Microsoft.Toolkit.Uwp and Microsoft.Toolkit.Uwp.Services)
  • Put a button on the form, create a click handler with the following code:
    private async void HandleButtonClick(object sender, RoutedEventArgs e)
    	TwitterService.Instance.Initialize( // change (1) - (3) for your app
    		"(1) ConsumerKey",
    		"(2) ConsumerSecret",
    		"(3) CallbackUri"); 
    	await TwitterService.Instance.LoginAsync();
    	tweets = await TwitterService.Instance.SearchAsync("hello world");
    	foreach (var tweet in tweets)
  • And that’s all it is to search Twitter for e.g. “hello world”!

Things to note:

  • Even though the API is really easy, it doesn’t mean that you can avoid reading or at least scanning the Twitter documentation altogether – you need to know just enough the get the required information for login.
  • Storing the ConsumerKey and ConsumerSecret in an app as plain text doesn’t sound like a good idea – I’ll have to read up on what best practices are in regard to security.

The Search for a Proportional Font for Developers

Tue, 14 Jun 2016 22:28:00 GMT

Text editors and IDEs usually use monospaced, i.e. non-proportional, fonts by default. This may seem like an obvious choice – after all, how else do you line up characters horizontally? The disadvantage of a monospaced font is that text lines can become relatively wide, because by definition, all characters have to have the same width as the character that requires the most space (the uppercase “W”). Back in the 80ies and early 90ies, with identifier names like “strnicmp()”, this wasn’t much of an issue. But then libraries grew and identifier names got longer and longer. At the same time, in my IDE the source code editor on one hand and an increasing number of additional panes on the other hand were competing for screen space. In the editor, I usually had a ton of unused whitespace behind short text lines, but when a line contained a slightly longer identifier, it often got clipped. That was the point when I asked myself how important exact horizontal alignment of characters was to me. Less horizontal scrolling and better readability for long names in return for giving up full control looked like deal good enough to give proportional fonts a try. The Switch I don’t quite remember the exact time when I switched; the blog post ”My Transition from Fixed to Proportional Width Fonts for Editing Source Code” is from 2004, years after the fact. What I do remember, though, is that it was the Verdana font that made the switch final. Verdana is a sans-serif font, except for serifs for the uppercase “I” to make it easily distinguishable from the lowercase “L”. Here’s a (wildly exaggerated) code example to demonstrate why this is important, first in Arial: …and here in Verdana: In Arial’s defense, I must say that I like Arial’s bold text much better than Verdana’s. And, for my personal taste, Verdana is a bit too wide (especially at larger font sizes). Its cousin Tahoma, on the other hand, is slightly too narrow: In the end I learned to live with Verdana, but when Segoe UI was introduced along Windows Vista, I switched immediately: Like Verdana and Tahoma, the bold version of Segoe UI is pretty thick, but I like keywords and class names being shown in bold (even if it’s too heavy). Noooooo…! After I upgraded my computer from Windows 7 to Windows 10 (I skipped Windows 8.x), I noticed Segoe UI had changed. The most dramatic change: The uppercase “I” lost its serifs (see: Segoe UI gets a subtle facelift in Windows 8)! Which means that the code example now looks like a soup of vertical bars: Searching for Alternatives With Segoe UI no longer suitable for source code and going back to Verdana not exactly an attractive option, I searched the web for alternatives. So far, I’ve come across the following fonts (in no particular order): Clear Sans (Intel, Clear Sans doesn’t seem to be hinted well enough for rendering at 10pt on a screen at around 96 pixel per inch, at least with ClearType on Windows (I don’t have a Mac for comparison). While it looks rather ugly on my machine, Clear Sans turns out pretty nice at 20pt or when I scale Visual Studio’s editor to 200%, so it may be a good choice for users with a HiDPI display. Source Sans Pro (Adobe, What I wrote about Clear Sans in regard to hinting is also valid for Source Sans Pro. For my personal taste, though, the difference between the uppercase “I” (without serifs) and the lowercase “L” (with only a small tail at the bottom) is too subtle, regardless of font size. PT Sans (ParaType, PT Sans Caption has serifs for the uppercase “I” and a tail at the bottom of the lowercase “L”, which is a bit too much in my opinio[...] – THE Resource for Monospace Fonts

Mon, 30 May 2016 19:49:29 GMT

While preparing an upcoming blog post about proportional fonts for programmers, I came across a tweet by Val Head (@vlh), pointing me to The website boasts the slogan “The most complete resource for monospace fonts on the web” and looking at the list of fonts, I’m inclined to believe it.

I browsed the site for a while until finally saw the link “Try them all online right now” which was hidden in plain sight directly in front of me:


The link opens a nice web application that lets you test drive a huge number of fonts, using a text of your choice. The available themes are a matter of personal taste, but this is mainly about getting an idea whether a font looks good before spending more time on it.


Nice Time Saver: Windows Universal App Image Scaler

Sat, 30 Apr 2016 07:29:00 GMT

Recently I took my first steps into the world of Universal Windows Platform (UWP) apps after many years of WPF. What came a bit as a shock to me was the sheer number of required/recommended tile and icon assets.

Most of the images are versions of the same image, scaled to different sizes. Of course, creating these images is something that can and should be automated, starting from a sufficiently large image.

One way to handle this is via Photoshop Actions, but when looking for a simpler solution I came across the Windows Universal App Image Scaler. This is a Visual Studio extension that adds a context menu entry to the Solution Explorer. You simply right-click an image file, choose “Scale image for Windows Universal app…” and specify the kind of images you want to create. When you press “Ok”, the output will be written to the directory that contains the source image, and that’s it!

You find this nice extension

The Importance of Empathy, pt2: It’s Good for You, Too!

Sun, 28 Feb 2016 23:31:47 GMT

In my recent blog post I described empathy as a valuable skill e.g. for UI design. But empathy is more than just “that UX soft skill thing”, “for making other people’s lives better”.In this post I’ll give two real-life examples where a lack of empathy significantly reduced the chances of success in a competitive situation – which should give food for thought even to the most selfish person.Example 1: Programming Contest EntriesIn 2004 I entered a competition for Visual Studio add-ins organized by Roy Osherove. Surprise #1: I won. Surprise #2: The blog entry “About the add-in contest results” by Frans Bouma, one of the judges.He wrote: “As a judge in the add-in contest, I had to test all the add-ins submitted, and judge them on quality and if they deserved any of the big prizes available. I can tell you it was hard. Not because there were so many good entries, but because it was often very hard to even get the submitted code to run, left alone to find any documentation what to do, how to get started.”Two years later I was in Frans’ shoes when I was a judge on a German contest for “code snippets” (more in the vein of small classes and helper methods than typical Visual Studio snippets e.g. for defining a constructor or a dependency property). I had to wade through more than 120 entries, with many lacking an easy to understand description of “what does it do”, “how do I use it”, etc.In both contests, not nailing the basics substantially influenced the judgement and thus prevented some of the entries from ranking higher.What went wrong?One possible short answer: People were lazy. They did the fun part (writing code), but skipped on the non-fun part (writing docs, taking care of setup, etc.). But on the other hand, people tend to overcome their laziness if they feel some kind of urgency.In the case of the contest, it seemed that many of the participants didn’t think that the out-of-the-box experience would be a factor in the review – which hints at a lack of empathy. Because with a bit of empathy, they would have thought about the situation of a contest judge.Let’s imagine that you are a judge for a programming contest. You unpack the ZIP file containing a contest entry and you get a bunch of files you’ve never seen before.What would be your first questions? Surely something like:Where do I start?Is there some kind of README?Is there a short introduction, maybe an elevator pitch for this?What is actually the problem this thing is trying to solve?What are the first steps that I should take?Can I simply follow the directions or are there prerequisites that aren't mentioned?Is there a simple way to achieve at least something in the software quickly before I dig deeper into it?Imagine you have to review not only one or two, but dozens and dozens of entries. Wouldn’t you be thankful for any entry that addresses these questions proactively?Now, after looking at a judge’s perspective: Would you, as the author of a contest entry, assume that a judge instantly sees how awesome your software is, without any explanation beyond a few words? And that none of the other contestants would come up with the idea to make things easier for the judges and thus make a good first impression?If you can now almost feel the pressure of competition – there’s the urgency required to overcome the laziness and the reluctance to do the things that are not fun.Example 2: Conference Session ProposalsI’m one of the organizers of the community conference “dotnet Cologne” which is wildly successful and has become the largest conference of its kind in Germany. One of the many things to do for the organizers in the months before the conference is to review a huge number of session proposals entered during the “call for papers”. We ha[...]

The Importance of Empathy

Sun, 31 Jan 2016 22:53:00 GMT

Empathy is (quote) “the capacity to understand what another person is experiencing from within the other person's frame of reference, i.e., the capacity to place oneself in another's shoes”. Putting yourself in other people’s shoes If you work on a piece of software, be it as a developer, a designer or a manager, then in your frame of reference, your software is the center of the world. It’s very tempting to think that in principle, people really would like to use your software, and that UX issues can be solved by improving the existing UI. Which isn’t wrong per se – after all, careful wording of UI texts, meaningful placement and spacing of UI elements does work wonders. On the other hand, it’s easy to fall into the trap of tweaking things up to no end instead of questioning the overall interaction, i.e. “lipstick on a pig”. In the frame of reference of the user, your software is just a thing that helps him/her to get things done. Users usually don’t actually want to use your software. They want to reach a specific goal and they know or least suspect that your software may be a way (or: one way) to achieve the desired result. That result is important to the user, not the software itself. If a user has problems with the software, that user will not necessarily think “oh, how much I’d like to use this excellent piece of software, I think I’ll read the tutorial”. No; in the user’s frame of reference, the software is a problem. Whether the user solves the problem (e.g. by putting more effort in learning the software) or avoids it (by using a different software or no software at all) depends on the assumed outcome and how valuable it is to the user. Excercise in empathy: Is it worth learning git? Let’s take a little detour: The distributed version control system (DVCS) called “git” is a complicated piece of software that draws criticism and ridicule on one hand, but is powerful enough to be in widespread use on the other hand. The situation in today’s software development is pretty simple: If you need to do the things that git does very well and/or if you (intend to) work on a project that is using git, you take the plunge and learn it, period. I do not use git (at the time of this writing). At work, I use the company-provided TFS, so I don’t need git there. And at home I chose Mercurial many years ago, at a time when git wasn’t that popular on Windows yet. If you are an avid git user, it is a perfect excercise in empathy to think about the reasons why I haven’t switched yet. You have to forget about the reasons why you love git and keep my frame of reference in mind. I use Mercurial for my (closed source) hobby projects, working both on my desktop at home and my laptop on the road. I spend quite time time on my hobby projects, but this time of course is limited (other hobbies, time with the wife, etc.). Switching the version control system takes away from that time; time that I could use to write that new feature that I have in my head for so long. So in this case, the outcome of switching isn’t valuable enough. Imagine you had written a tool for a Mercurial-to-git repository conversion and would wonder whether a blue button or a green button in your tool’s UI would increase the probability of me switching – that would be the wrong question caused by the wrong frame of reference. The ability to leave your current point of view for a moment and to put yourself in other people’s shoes is a highly valuable skill. Of course it does not mean that you have to agree with the other point of view (otherwise police profilers would all have to be serial killers), but leave your experien[...]

My First Post Using Open Live Writer

Wed, 09 Dec 2015 22:51:00 GMT

I have been using Windows Live Writer for writing blog posts since 2008. It was kind of sad to see that active development stopped after the last release in 2012. So it was an early Christmas present for me when I read the announcement that Live Writer is now open source.

Open Live Writer is available for download on, the source code is hosted on GitHub.

UX-Vortrag von der NRW Conf 2015 als Video auf Channel 9

Planning to Give a (Developer) Talk? Read this Article!

Sat, 31 Oct 2015 11:07:40 GMT

If you plan to speak at a conference or a user group meeting, “How To Deliver a Great Technical Presentation” by James Montemagno contains valuable tips.

The article contains virtually everything that I – from my personal experience of giving both technical (developer) and (a bit more “fluffy”) user experience talks – would recommend.

Some comments on just a few of the points he mentions:

  • Prepare that IDE – definitely; it always amazes me when speakers are “surprised” by the lower resolution of a projector.
  • Stop Using Dark Themes – oh yes, please!
  • Master Zooming – all my recent (UX) talks have been slide-only, but note to myself: This is something I should practice before my next developer talk.
  • Acquire the Right Equipment – …and make sure you always have batteries ready just in case your presenter device runs out of juice (or, when in doubt, replace the batteries before the talk). Regarding the bottle of water: I always bring my own water to avoid surprises (unexpected taste, lack of non-carbonated water at the venue)
  • Practice, practice and practice some more! –  I find it very helpful to actually stand up, even if I’m doing just a quick “voice in my head” walk-through.

Great article, highly recommended (and the people in the comments seem to agree).

UX-Vortrag auf der NRW Conf 2015

Sun, 13 Sep 2015 13:43:00 GMT

Am 8. und 9. Oktober 2015 findet in Wuppertal die NRW Conf 2015 statt, bei der ich in diesem Jahr als Sprecher dabei bin. Ich freue mich schon sehr auf dieses Community Event und vor allem darauf, mal mehr Zeit für spannende Gespräche mit den anderen Sprechern zu haben, als es sonst im Rahmen der dotnet Cologne (bei der ich als Mitveranstalter immer irgendwie unter Strom stehe) möglich ist.

Mein Vortrag trägt den Namen “Spaß, Verwirrung, Furcht und Basketball – User Experience unter Stress” und beschäftigt sich mit den Lehren aus Situationen, in denen ein eigentlich gut geschulter Anwender unter Stress plötzlich Probleme hatte, eine Software zu bedienen.

Konkret – und daher stammt das “Basketball” im Titel des Vortrags – geht es um eine Software für Video-Leinwände und LED-Werbebanden, die ich für den Basketball-Bundesligisten Telekom Baskets Bonn schreibe. Man möchte meinen, dass ich als Autor die Software in- und auswendig kennen sollte. Und doch spielen da unter dem Druck, vor 6000 Zuschauern möglichst nicht zu versagen, bei der Bedienung menschliche Faktoren eine große Rolle. Aus den wertvollen Erfahrungen habe ich eine Reihe von “Lessons learned” herausgepickt, die ich in dem Vortrag vorstelle. Und die im Kern relativ wenig mit Veranstaltungstechnik zu tun haben, sondern auch z.B. für Business-Anwendungen gelten.

Die Anmeldung zur NRW Conf ist mittlerweile offen, vielleicht sieht man sich dort?

SonicFileFinder 3.0 Released

Mon, 17 Aug 2015 22:57:46 GMT

My colleague Jens Schaller has released version 3.0 of his free Visual Studio extension SonicFileFinder, now with support for Visual Studio 2015.

SonicFileFinder is comparable to ReSharper’s “Go to File” feature; both let you search for files in the projects of the currently loaded solution. One of the key differences is that SonicFileFinder remembers the search term whereas in ReSharper you start from scratch each time. SonicFileFinder recreates the result list blazingly fast and if you want to enter a different search term, you can start typing immediately.

You’ll learn to love SonicFileFinder’s approach when you have several files in the result list and you don’t quite know which one may be the one you are actually looking for. You open a file e.g. by pressing Enter, see that it’s not the one you wanted, hit the hotkey (Ctrl+Shift+Y by default) again and simply choose another one from the list – without having to enter the search term again. Alternatively, you could also select multiple files and open them at once.


SonicFileFinder has a couple more nifty features; head over to the SonicFileFinder website for the complete list and some screenshots that give you a good idea what this excellent Visual Studio extension has to offer.

WebAssembly – A new Hope

Tue, 30 Jun 2015 06:29:00 GMT

Recently, WebAssembly was announced, a new standard that defines a binary format and execution model for the Web. With Google, Mozilla, Microsoft and others voicing their support, my first thought was: Wow, so there is actually hope to get rid of JavaScript someday! In this blog post I’ll explain why I think WebAssembly is such a big step in the right direction, even if it’s something that won’t have an immediate impact. What’s the problem with JavaScript, anyway? JavaScript is a programming language that has quirks (see Seven JavaScript Quirks I Wish I’d Known About or JavaScript garden), lacks important features (e.g. proper arithmetic data types) and isn’t type safe (by design). All this doesn’t matter for JavaScript’s original purpose – writing a few lines of script code. In fact, the dynamic nature of JavaScript, i.e. being able to add object properties or change data types on the fly, enables some pretty elegant solutions. But writing large amounts of JavaScript in a team of average developers comes with a risk that is higher than in other languages. Bugs that the compiler for a typed language would catch immediately can remain unnoticed for a long time. Renaming identifiers (via find-and-replace in a text editor) or refactoring code can be downright dangerous. Anders Hejlsberg puts it this way: “[…] you can write large programs in JavaScript. You just can’t maintain them.”. So why are people using JavaScript? JavaScript in the browser (used in conjunction with other web technologies) enables highly responsive, cross-platform, zero-deployment applications… …without any additional client installation (most would consider their favorite non-IE-browser as part of the “basic operating system setup” before any work can be done on a new computer) … … and is good enough for developing almost any kind of application – at least given enough time, budget and/or determination. The problem: this “good enough” is an enormous hurdle for any alternative technology. At this point in time, it’s totally unrealistic that a completely new technology will magically appear and win the uphill battle to be available on all platforms, with the same reach as JavaScript-enabled web browsers. Fact is, JavaScript (plus other web tech) won. Some people are perfectly fine with this, others (me included) are a bit skeptical what this means for the future of software development –  to put it mildly. Is JavaScript the QWERTY of programming languages? I started programming in 1983 and since then I’ve witnessed incredible progress. From writing Z80 code that fit into a few kilobytes of RAM to simply using a component without caring, or even knowing, what language it was written in.
