Mocking framework for asp.net core 5.0

Question

I recently installed Visual Studio 2015 and started a project with a web site and a asp class library which will contain the unit tests for the web site. I usually use Moq for mocking but I am no stranger to try a different mocking framework. The problem I am having is that I added Moq as a reference to the unit test project and started using it. Everything seems fine at first until I tried to compile.

When I compiled I got an error message saying:

ASP.NET Core 5.0 error CS0246: The type or namespace name 'Moq' could not be found (are you missing a using directive or an assembly reference?)

I noticed that I could switch between ASP.NET 5.0 and ASP.NET Core 5.0 in the code view and when selecting ASP.NET Core 5.0 I get errors but no when selecting ASP.NET 5.0. I tried searching for an answer but I did not have any luck.

Is the problem that Moq does not work with vnext and I should use a different framework (if so which works?) or can I solve this somehow? My project.json:

{ "version": "1.0.0-*", "dependencies": {     "Web": "1.0.0-*",     "Xunit.KRunner": "1.0.0-beta1",     "xunit": "2.0.0-beta5-build2785",     "Moq": "4.2.1409.1722" },  "frameworks": {     "aspnet50": {         "dependencies": {         }     },     "aspnetcore50": {         "dependencies": {         }     } }, "commands": {     "test": "Xunit.KRunner" }  }

ASP.NET team from Microsoft have created a special version of Moq for internal usage. You can find a fork project on the asp.net github page.

How to use that?

• Register a Moq dependencies in project.json:

  {     "frameworks": {         "dnx451": {             "dependencies": {                 "Moq": "4.2.1312.1622"             }         },         "dnxcore50": {             "dependencies": {                 "moq.netcore": "4.4.0-beta8"             }         }     } } 

• Create a NuGet.config file in project home directory.

  <?xml version="1.0" encoding="utf-8"?>     <configuration>         <packageSources>             <add key="AspNetVNext" value="https://www.myget.org/F/aspnetcidev/api/v3/index.json" />             <add key="NuGet" value="https://api.nuget.org/v3/index.json" />         </packageSources>     </configuration> 

And use Moq! :)

I suppose that so far a version of Moq that works with asp.net core 5.0 is not available in the nuget feed, but I think you can work with Asp.Net 5.0.
