Simple example project showing how to use xunit with PowerShell projects that target netstandard.

• To pull in Microsoft.PowerShell.SDK you need the nuget.config file.
• The SDK is required when running tests because xunit tries to use the reference library. All of the methods/properties in the reference library are empty and return null
• A new configuration was added for Test that must be specified when running xunit tests
• Customizations in the sln file prevent the tests from being built in any configuration other than Test. See "Solution File Changes" for more info

1. The configuration Test was added for all projects
2. The .Build.0 option was removed for all configurations other than Test in the xunit project.

You can make these changes with the configuration manager in Visual Studio, or you can do the following manually.

1. Under the following text

       Release|Any CPU = Release|Any CPU
       Release|x64 = Release|x64
       Release|x86 = Release|x86
   

   Add this

       Test|Any CPU = Test|Any CPU
       Test|x64 = Test|x64
       Test|x86 = Test|x86
   

2. Find the text that looks like this, except where {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX} is the Guid of your test project.

       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|Any CPU.Build.0 = Debug|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|x64.ActiveCfg = Debug|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|x64.Build.0 = Debug|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|x86.ActiveCfg = Debug|x86
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|x86.Build.0 = Debug|x86
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|Any CPU.ActiveCfg = Release|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|Any CPU.Build.0 = Release|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|x64.ActiveCfg = Release|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|x64.Build.0 = Release|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|x86.ActiveCfg = Release|x86
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|x86.Build.0 = Release|x86
   

   And modify it to look like this

       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|x64.ActiveCfg = Debug|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Debug|x86.ActiveCfg = Debug|x86
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|Any CPU.ActiveCfg = Release|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|x64.ActiveCfg = Release|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Release|x86.ActiveCfg = Release|x86
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Test|Any CPU.ActiveCfg = Test|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Test|Any CPU.Build.0 = Test|Any CPU
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Test|x64.ActiveCfg = Test|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Test|x64.Build.0 = Test|x64
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Test|x86.ActiveCfg = Test|x86
       {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}.Test|x86.Build.0 = Test|x86
   

   Note: Make sure to remove the lines with .Build.0 for configurations other than test.

1. cd .\test\DemoAssembly.Tests
2. dotnet xunit -fxversion 2.0.5 --configuration Test

_{Note: "fxversion" will vary depending on what runtimes are installed.}
