Brand new project does not compile in Release

[ArchieCoder]

Current behavior

I have this error:

1>C:\Program Files\dotnet\sdk\9.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.ConflictResolution.targets(112,5): error NETSDK1152: Found multiple publish output files with the same relative path: D:\source\UnoAppRelease\UnoAppRelease\obj\Release\net8.0-windows10.0.26100\MsixContent\resources.pri, D:\source\UnoAppRelease\UnoAppRelease\bin\Release\net8.0-windows10.0.26100\resources.pri.

Expected behavior

No compilation error

How to reproduce it (as minimally and precisely as possible)

1- Create new project, select Skia (Desktop/Linux/Mac) and Windows only
2- Change target to Release
3- Compile

UnoAppRelease.zip

Thanks for the report, @ArchieCoder. I'm not able to reproduce this issue, can you provide a binlog?

[ArchieCoder]

It works now 🤔. I did nothing different. There are 3 weird errors below.

If the warnings are harmless, you can close the issue. Thanks.

Thanks! Those three errors will be fixed in a upcoming uno.sdk service release.

Would you have changed the target framework between tests? Or maybe built with a different version of VS? Sometimes the caches in obj get confused.

I actually just reproduced it with a new project again:

1- Create the project Skia + Windows
2- Compile Debug (success)
3- Compile Release

Here is the binlog

I just tried your steps, but I still can't repro. I would not be surprised if it's some kind of design-time issue in winappsdk. Does it happen if you clear the obj and build again?

[ArchieCoder]

Deleting the obj/bin does the job. I even got the error when creating a blank solution + compile in debug.

I think I know the issue: I was not patient enough to let the solution loads completely before building. If I wait long enough, it works.
