Publish to IIS Fails


Hello Everyone

I have created a simple core web api. I have configured the IIS web site (http://localhost:port), changed to "No Managed Code".

When I try to deploy the web api from Visual Studio 2015 using publish it fails with the following error:

Web deployment task failed. (The specified credentials cannot be used with the authentication scheme 'Basic'.)

The specified credentials cannot be used with the authentication scheme 'Basic'. Default credentials cannot be supplied for the Basic authentication scheme.

Parameter name: authType

What am I missing?

FormView - update with custom code?



I have a FormView, which is based on a SqlDataSource.
The SqlDataSource has a SelectCommand, but no UpdateCommand.

When the user edits the form and presses "update", I get an error message, because there is no update command.

However, in this case I cannot specify a single SQL command as the update command. Instead, I have to do it in C#.

How can I realize this?


SignalR Application Code Review


Hello everyone! I've recently started with SignalR and have made a very small web app. You can see its humble beginnings here, (please ignore the unfinished content on the root domain (image) ). The source code is here,

Essentially, all the app does is ask for your name, then places your name on the screen. You can move your name with WASD. It uses SignalR to make it possible for multiple people to join.

Being so new to SignalR, I'm here to ask for general advice. By looking at my source code, does anything pop-out as a bad practice? Or, are there certain practices that I should be exercising, but I'm not?

My next milestone will be adding unit tests, something I've never done before this project. So I feel that it would be best to make sure that I'm using SignalR correctly before I begin writing tests.

Thanks for taking the time to read this. Any advice at all would be very appreciated.

mvc pagination


 job = entities.Jobs.Where(x => x.Industry.Industry1.StartsWith(searchTerm)).OrderBy(x => x.JobTitle).Skip(pageNumber - 1).Take(resultPerPage).ToList();

i am trying to implement pagination so that the data in the model job is not fetched all at a time,only that much data is fetched (resultPerPage) like if page no 1 is clicked and user has selected resultPerPage=5 so only 5 jobs are fetched from db, thrn if user selects page no 3 then data from 10-15 is fetched from db rather than fetching all data at same time and then applying paging to that. how can i achieve this, can  u provide some example?.
