Can't run dotnet test against a multi-targeting net8.0/net48 project

Hi,

I am not sure if this problem is xunit or vstest (or dotnet test) related, but I have trouble running a simple xunit test project using dotnet test on Windows when a test project targets both .NET 4.8 and .NET 8.0.

Steps to reproduce (I also created a simple repo here: https://github.com/tbolon/vstest-lab)

Create a simple class lib project dotnet new classlib
Add xunit and xunit.runner.visualstudio packages: dotnet add package xunit & dotnet add package xunit.runner.visualstudio
Change the project to target both .net8.0 and net48:<TargetFrameworks>net8.0;net48</TargetFrameworks>.
Remove c# features not supported by .net 4.8: ImplicitUsings and GlobalUsings

Change the Class1.cs for this:

namespace ClassLib1
{
public class Class1
{
[Xunit.Fact]
public void Test1() { }
}
}

Run dotnet build and dotnet test
The tests are run against .NET 4.8 and fail against .NET 8.0

The console output is:

Passed!  - Failed:     0, Passed:     1, Skipped:     0, Total:     1, Duration:  - ClassLib1.dll (net48)

The interesting error is: An assembly specified in the application dependencies manifest (ClassLib1.deps.json) was not found: package: 'xunit.abstractions', version: '2.0.3' path: 'lib/netstandard2.0/xunit.abstractions.dll'.

Running with -f net48 works. Running with -f net8.0 gives the same error.

Obviously, Adding the xunit.abstractions package does not fix the problem.

When running with the --diag:log.txt I get the following output:
