[Regression] Failed to discovery tests for "UITests" with error "System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types" appeared

[PhoebeTf]

Describe the bug

This is a regression issue, feature works well on 17.9, broken from 17.10.0 Preview 1.0 [34607.79.d17.10]

Steps to reproduce the bug

1. Download the project from github microsoft/WinUI-Samples: Official repository for WinUI sample code (github.com)
2. Extract the project and launch solution "UITests.sln"
   (Note: need update the code for "bool isCausalitySupported()" in "xx:\WinUI-Samples-main\WinUI-Samples-main\Shared\WinUISplashScreen\Native\ppltasks.cpp" as feature change mentioned in https://github.com/microsoft/WinUI-Samples/issues/193
3. Wait for the solution load completely
4. Add Nuget source for "https://api.nuget.org/v3/index.json" and "C:\Program Files (x86)\Microsoft SDKs\NuGetPackages" under "Package Sources" tab for "Nuget Package Manager"
5. Restore NuGet package for solution
6. Build project "UITests"
7. Open Test->Test Explorer
8. Click "Run All Tests in View"

Actual:
Only 1 test for UnitTest was found and 1 Error appeared

Error info:
Could not determine target device configuration. Exception: System.Runtime.InteropServices.COMException (0x80020009): The method or operation is not implemented.
