我正在尝试创建一个 MSTest 项目来对 WinUI 3 开发进行单元测试。当针对 .NET 5.0 时，我能够通过测试资源管理器运行测试。
Project Reunion 需要 net5.0-windows10.0.19041 作为目标框架。当我尝试运行针对 net5.0-windows10.0.19041 的测试时，项目会构建，但测试不会运行。下面的测试日志的输出表明未找到 WinUI3-UnitTests.dll 文件，但指定位置中确实存在 WinUI3-UnitTests.dll。
[2021-10-05 9:38:57.350 AM] [MSTest][Discovery][WinUI3-Demo\WinUI3-UnitTests\bin\Debug\net5.0-windows10.0.19041\WinUI3-UnitTests.dll] Failed to discover tests from assembly WinUI3-Demo\WinUI3-UnitTests\bin\Debug\net5.0-windows10.0.19041\WinUI3-UnitTests.dll. Reason:File does not exist: WinUI3-Demo\WinUI3-UnitTests\bin\Debug\net5.0-windows10.0.19041\WinUI3-UnitTests.dll
在 MSTest 输出日志中，它抛出 System.InvalidOperation 异常
