I have a .net core test app that's referencing a .net framework 4.7.1 project. I've updated the project file of the .net core project so that it looks like this...
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net471</TargetFramework>
<IsPackable>false</IsPackable>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Extensions.Configuration" Version="2.0.0" />
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.3.0-preview-20170628-02" />
<PackageReference Include="xunit" Version="2.2.0" />
<PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" />
</ItemGroup>
<ItemGroup>
<ProjectReference Include="..\PushNotifications\PushNotifications.csproj" />
</ItemGroup>
</Project>
When I debug a test, I get..
Catastrophic failure: System.TypeInitializationException: The type
initializer for 'Xunit.DiaSession' threw an exception. --->
System.IO.FileNotFoundException: Could not load file or assembly
'System.Reflection.TypeExtensions, Version=4.1.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The
system cannot find the file specified.
Adding System.Reflection.TypeExtensions to either project has no effect.
What else do I need to do?

How do I fix this issue ? Unable to add PCL reference to my Unit Test Proj.
PCL proj is using framework NetStandardLib v2.1
Testing this, NUnit Test project doesn't let you switch between Framework and Core once you have created it. Perhaps because different PackageReferences are needed.
Safest fix is to create a new NUnit Test project. But this time, when it asks for target Framework, pick a .Net core one. Probably pick the highest number it offers (Core 3.1).
Then copy or move all your test source files into it.
Looking at a Framework Test Project vs a Core one, these are the lines that are different.
Framework:
<PropertyGroup>
<TargetFramework>net48</TargetFramework>
...
<ItemGroup>
<PackageReference Include="NUnit" Version="3.12.0" />
<PackageReference Include="NUnit3TestAdapter" Version="3.16.1" />
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.5.0"/>
</ItemGroup>
...
Core:
<PropertyGroup>
<TargetFramework>netcoreapp3.1</TargetFramework>
...
<ItemGroup>
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.1.0" />
<PackageReference Include="NUnit" Version="3.13.3" />

When I try to create a BitmapImage instance (under WinUI 3) I get an exception that a necessary class is not registered. This is taking place within Visual Studio 2022, within an xUnit based test project.
The line throwing the exception is simply:
var retVal = new BitmapImage();
Given how simple the line is I'm wondering if there's something wrong with my xUnit project setup. Here it is:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net6.0-windows10.0.19041.0</TargetFramework>

</PropertyGroup>
<ItemGroup>
<PackageReference Include="FluentAssertions" Version="6.6.0" />
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.1.0" />
<PackageReference Include="xunit" Version="2.4.1" />
<PackageReference Include="xunit.runner.visualstudio" Version="2.4.3">
<IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>

</PackageReference>
<PackageReference Include="coverlet.collector" Version="3.1.2">

<PrivateAssets>all</PrivateAssets>
</PackageReference>
</ItemGroup>
<ItemGroup>
<ProjectReference Include="..\MapLibraryWinApp\MapLibraryWinApp.csproj" />
</ItemGroup>
</Project>
Here's the project file for the library containing the code I'm trying to test:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>

I thought perhaps the test project might need to contain the <UseWinUI> tag, but adding it did not solve the problem.
You need to run an actual packaged WinUI app or deploy the Windows App SDK runtime along with a non-MSIX-packaged app to be able to use the WinUI types.
I am afraid it's not as simple as simply referencing the WinUI code from a standalone testrunner app.
Please refer to this blog post for an example of how to set up an actual app that runs the tests. Or avoid creating UI specific stuff in your unit tests.
I have a Blazor project with a T4 template I wrote for scaffolding some code automatically. It works great from within Visual Studio, but I have to modify & save the template to get it to run again (as documented and expected).
I also want to run the template when building the project, so instead of VS running the template, it has to be MSBuild. I went through a bunch of articles about the topic and it looks like I have to re-import the default targets, as explained here.
I added the following to the top of my .csproj file, and this is when things went south:
<Import Project="Sdk.targets" Sdk="Microsoft.NET.Sdk.Web" />
This is the error I'm getting:
The TargetFramework value 'netstandard2.1' was not recognized. It may
be misspelled. If not, then the TargetFrameworkIdentifier and/or
TargetFrameworkVersion properties must be specified
explicitly. TestProject C:\Program
Files\dotnet\sdk\3.1.401\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets 93
Full .csproj file:
<Project Sdk="Microsoft.NET.Sdk.Web">
<Import Project="Sdk.targets" Sdk="Microsoft.NET.Sdk.Web" />
<PropertyGroup>
<TargetFramework>netstandard2.1</TargetFramework>
<RazorLangVersion>3.0</RazorLangVersion>
</PropertyGroup>
<ItemGroup>

<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.Build" Version="3.2.1" PrivateAssets="all" />

<PackageReference Include="System.Net.Http.Json" Version="3.2.0" />
</ItemGroup>
</Project>
What am I missing/doing wrong?
You should note the info from the article:
Fortunately, there’s a workaround: you can import the default targets
file explicitly, and import the text templating targets after that:
Solution
You should import those targets after netstandard 2.1 node.
In my side, I use these:
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netstandard2.1</TargetFramework>
<RazorLangVersion>3.0</RazorLangVersion>
</PropertyGroup>
<Import Project="Sdk.targets" Sdk="Microsoft.NET.Sdk.Web" />
<Import Project="$(VSToolsPath)\TextTemplating\Microsoft.TextTemplating.targets"/>
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="3.2.1"/>
<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.Build"
Version="3.2.1" PrivateAssets="all" />
<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer"
Version="3.2.1" PrivateAssets="all" />
<PackageReference Include="System.Net.Http.Json" Version="3.2.0"/>
</ItemGroup>
</Project>
Then,
In Visual Studio 2017, I got an error in all projects that are related with ASP.NET Core 2 .
That says:
unable to run your project. the runcommand property is not defined
Even I uninstalled the VS and again installed it but I have still this problem.
I tested default project template for VS but those do not execute right, too.
Please help me.
