[MAUI] MacCatalyst parallel build issue #17497
Description
Steps to Reproduce
- Build dotnet/maui's repo, namely for MacCatalyst
- Sometimes you get errors about
.pdbfiles such as:
Errors
/Users/builder/azdo/_work/2/s/bin/dotnet/sdk/7.0.102/Microsoft.Common.CurrentVersion.targets(4752,5): error MSB3027: Could not copy "obj/Release/net7.0-maccatalyst/Microsoft.Maui.pdb" to "bin/Release/net7.0-maccatalyst/Microsoft.Maui.pdb". Exceeded retry count of 10. Failed. [/Users/builder/azdo/_work/2/s/src/Core/src/Core.csproj]
/Users/builder/azdo/_work/2/s/bin/dotnet/sdk/7.0.102/Microsoft.Common.CurrentVersion.targets(4752,5): error MSB3021: Unable to copy file "obj/Release/net7.0-maccatalyst/Microsoft.Maui.pdb" to "bin/Release/net7.0-maccatalyst/Microsoft.Maui.pdb". The process cannot access the file '/Users/builder/azdo/_work/2/s/src/Core/src/bin/Release/net7.0-maccatalyst/Microsoft.Maui.pdb' because it is being used by another process.

I think this occurs if you have multiple MacCatalyst app projects in a solution and build them. I think it might have been introduced when RuntimeIdentifiers=maccatalyst-x64;maccatalyst-arm64 became the default? But also might be combination of some change in the .NET SDK or MSBuild.
The workaround is either:
- Build
.slnfiles with-m:1 - Build with
-r maccatalyst-x64
This is what I did for now:
dotnet/maui@440fd19#diff-74e588eb60cf3c891901dd5657c29e2b0b0b1e605a91d5f04220301ff4a5295bR14
Expected Behavior
No build errors.
Actual Behavior
Got a build error.
Environment
This was the versions from dotnet/maui#13201
