ASP .NET Core - Windows Service - Make it secure using https



I have ASP .NET Core web API running as a windows service on a port, 60001.

public static void Main(string[] args)
            bool isService = true;
            if (Debugger.IsAttached || args.Contains("--console"))
                isService = false;

            var pathToContentRoot = Directory.GetCurrentDirectory();
            if (isService)
                var pathToExe = Process.GetCurrentProcess().MainModule.FileName;
                pathToContentRoot = Path.GetDirectoryName(pathToExe);

            var config = new ConfigurationBuilder()
                //Specifying the IP or host ASP.NET Core listens on
                .AddJsonFile("hosting.json", optional: false, reloadOnChange: true)

            var host = new WebHostBuilder()

            if (isService)

After the Windows Service is started, I'm able to access it using http://machinename:60001/api

Now, the requirement is to make it secure with https. I do have purchased a SSL certificate available (NOT self signed) and I'm wondering how would I apply the certificate since I'm running it as a Windows Service. 

Any help will be appreciated.

I have a Microsoft Flow setup with the following steps When a file is created (SharePoint) (this is pointing to a specific document library Http (Http), Method: Post, Uri (pointing to my app), Body: File Content from the SharePoint step above. My app that I have written is hosted in an Azure Web App and is written in C# in ASP.NET Core.  I'm trying to convert the information that is coming into me from Flow back into the original document and I cannot figure out what is being sent.  When I look in Flow it says the body of the request that was sent is: { "$content-type": "image/jpeg", "$content": "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" } In my application I originally tried to have a method that looks like  [HttpPost] public IActionResult Process(List files) but that flow is not submitted a file, so I changed it to the below method [HttpPost] public IActionResult ProcessJson([FromBody]FlowFile file) {... } public class FlowFile { [JsonProperty(PropertyName = "$content-type")] public string ContentType { get; set; } [JsonProperty(PropertyName = "$content")] public string Content { get; set; } } I also added a block of middleware, so that I could get the actual request body stream.  The middleware that I added has method that looks like this public async Task Invoke(HttpContext context) { var requestBodyStream = new MemoryStream(); var originalRequestBody = context.Request.Body; await context.Request.Body.CopyToAsync(requestBodyStream); requestBodyStream.Seek(0, SeekOrigin.Begin); var requestBodyText = new StreamReader(requestBodyStream).ReadToEnd(); var bytes = StringToByteArray(requestBodyText); LogRequestMiddleware.LastBody = System.Text.Encoding.Default.GetString(bytes); requestBodyStream.Seek(0, SeekOrigin.Begin); context.Request.Body = requestBodyStream; await next(context); context.Request.Body = originalRequestBody; } private static byte[] StringToByteArray(string hex) { return Enumerable.Range(0, hex.Length) //.Where(x => x % 2 == 0) .Select(x => Convert.ToByte(hex.Substring(x, 1), 8)) .ToArray(); } When I do this The response that I get is below and I cannot figure how to get it back to the correct string that I want. �����JFIF��`�`�����C�   &#[...]

How to replace Core MVC Carousel first image



I created an ASP.NET Core 1.1 MVC Web Application in Visual Studio 2017 Community.

I am trying to replace the first image in the carousel on the Home page with a link coding from my Microsoft affiliate account.

Here is what the original Index.cshtml first item code looks like:


Here is the code that I get from the affiliate website:


I tried to modify the code for the first carousel image to look like this:



It displays the image, but it does not allow me to click it for the destination URL and the navigation arrows and dots do not appear correctly.  This is what it looks like:


I understand that the original image that is displayed is the wwwroot\images\banner1.svg file.  I do not want to replace that file.  I want to replace the image that is displayed in the carousel.

Does anyone know how I can get this coding to work as one of the items in the carousel?

IrouteConstraint how to do in


I am trying to create a IrouteConstraint for a cms controller to match on slugs. However I am using core and I cant seem to find a way to resolve httpcontextbase. I was going by the msdn

[TypeForwardedFrom("System.Web.Routing, Version=, Culture=Neutral, PublicKeyToken=31bf3856ad364e35")]
public interface IRouteConstraint
    bool Match(HttpContextBase httpContext, Route route, string 
    parameterName, RouteValueDictionary values, RouteDirection routeDirection);

Obv I cannot reference system.web as its not in core so what do I reference in core 1.2 to get this to work or is their a new way of doing this.

Basically what I want to achieve is / friendly url then if a person choose a parent category it would go cms driven page.

Base in mind im using lattest core

I no I will need a controler like CmsController with the pages and actions to write the field that will house the content what is the best way also to output the content to the view these days is it still output to something like a litterial control?

ASP.NET Core Authentication problem on Windows Server 2008


After publishing an ASP.NET Core MVC app to a Windows Server 2008 host and trying to authenticate in I get a "This page can’t be found".

The guide I've used to set it up:

On a local machine everything's perfect but on production server it just won't authenticate even though it's pointing to the same database.

Logging doesn't help much, all I get is:

No webpage was found for the web address: http://servername/TestApp/Account/Login?returnurl=%2FTestApp%2F


2017-08-07 09:24:37 POST /TestApp/Account/Login returnurl=%2FTestApp%2F 80 - Mozilla/5.0+(Windows+NT+10.0;+Win64;+x64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/60.0.3112.90+Safari/537.36 http://servername/TestApp/Account/Login?ReturnUrl=%2FTestApp%2F 404 0 0 2234

I'm using AspNetCore 1.1.0 and AspNetCore.Identity.EntityFrameworkCore 1.1.0

I suspect something related to Identity is not working on live server but how can I diagnose it? Stdout is enabled in web.config but I'm not getting any error logs.

Applying the concept of VB Module in C#


So I used to write my functions in VB module and call them from any  place in the project, I don't know how to do it in C#.

This is my current function in the controller

private readonly ApplicationDbContext _context;

        public PatRegController(ApplicationDbContext context)
            _context = context;

  public Int64 GetSerial()
            List NewFileSeq = new List();
            NewFileSeq = _context.FileIdSeq.FromSql("FileIdSeqSP").ToList();
            var FileID = NewFileSeq[0].LastSequence;
            return FileID;

and I call it 


Now I moved it to another static class so I can initialize it from any place as follows

namespace ARTNetCore.Functions
    public static class DbSerializers
        private static readonly ApplicationDbContext _context;
        public static Int64 FileIdSerial() {
            List NewFileSeq = new List();
            NewFileSeq = _context.FileIdSeq.FromSql("FileIdSeqSP").ToList();
            var FileID = NewFileSeq[0].LastSequence;
             return FileID;

and I call it in my controller like,

        public async Task Create([Bind("FName,MName,LName,Dob,GenrId,StasId,NatyId,MarsId,CouyId,StaeId,CityId,OccnId,Email,SNN,PassNo,MobNo,LLine,MAdds,StrtNo,SDirn,AptNo,Locy,ALevl,PCode,Couy,ProeId")] PatReg patReg)
            if (ModelState.IsValid)
                patReg.FileId = DbSerializers.FileIdSerial();
                await _context.SaveChangesAsync();
                return RedirectToAction(nameof(Index));
            return View(patReg);

But I m getting an error 

An unhandled exception occurred while processing the request.

NullReferenceException: Object reference not set to an instance of an object.
NewFileSeq = _context.FileIdSeq.FromSql("FileIdSeqSP").ToList();

what am i missing here

Windows Authentication to make SQL Server Connection


I have a .NET Core Web API Service which requires to connect to the SQL Server database using Windows Authentication. This is how it should work (raw):
1) The Windows username and password will be passed to the service method.
2) With the supplied username and password the service will make a trusted windows authentication to the SQL Server database.
I'm not sure how I will make use of the Windows Identity classes to build this.
Any help will be appreciated.

Adding Controller with views using Entity Framework Error - Visual Studio 2017 Preview (2)


I'm cross posting this because it might make more sense here vs the Visual Studio MSDN forum.

Trying to follow the tutorial for the MVCMovie project located at :

Getting the following error when trying to add a controller to the project.  Error is:

Scaffolding failed to edit Startup class to register the new Context using Dependency Injection. Make sure there is a Startup class and a ConfigureServices method and Configuration property in it.

I can add an empty controller and a controller with read/write actions, just not the one with the EF framework.

Any ideas other than waiting for an update to the IDE?
