@alirezanet Can you please merge this and make a new release? It fixes 2 issues I encountered:

• file not found error when not publishing symbols using the latest dotnet 6.0.2 (explained here [Bug]: error: File does not exist (true) while executing dotnet nuget push command NuGet/Home#11601 (comment))
• explicit and transient dependencies are not packed when adding them in AddGenerationTimeReferences if the dotnet pack command is executed with --no-build parameter

[alirezanet]

Sure thanks. 👌

Since this change i have a problem publishing a C# CodeGen Package.

With 3.0.0 it works.

Yeah, Looks like this PR have added more issues, I've had a few problems too
Until we fix this, use the v3.0.0.

Sorry about that. For my nugets (using latest dotnet 6.x) it works fine.
@FabianTerhorst seems that dotnet pack fails to build properly.

@alirezanet since my issue was that running build before pack was missing some dlls in the nuget, maybe an extra flag SKIP_BUILD which by default would be false (so it doesn't break existing actions) would solve this? I just tested on my project that had the issue and keeping the dotnet build step and after running dotnet pack is a viable solution as well as long as it doesn't contain the flag --no build. The pack time is the same since it determines that All projects are up-to-date for restore.
