Is your feature request related to a problem? Please describe.
The CS8002 warning (referenced assembly doesn't have a strong name) is irrelevant on modern .NET runtimes - all such checks have been removed from the runtime. As a result any such diagnostics are noise to users.
Describe the solution you'd like
The SDK should detect when C# is the project language and the TFM is a .NET Core TFM and append CS8002 to the existing NoWarn list if able in its MSBuild Targets.
