[WSA] TargetInvocationException when re-importing UWP .dll

Windows Store Apps



Priority: 2Necessary for shipping a final release


Severity: 3Secondary functionality broken

Plugin targets UWP platforms (Windows 10, HoloLens, etc) which uses .NET Core 5.0. In plugin inspector .dll is set as "don't process", but editor still throws errors when reimporting.

Reproducible on 5.3.5f1, 5.3.6f1, 5.4.0f3.

Repro steps:
1. Open project "".
2. Reimport plugin in editor and observe the error in the console.

Error in the console:
