build for upload failed ( Payload contains two or more files with the same destination path )

Question

While I could build each release config separately, I could not create a release/upload package using the "Create App Package" wizard.

Already read related topics. (Payload contains two or more files with the same destination path 'System.Diagnostics.Tools.dll')

I tried

1. deleting the obj folder
2. deleting the bin folder
3. clean solution for each build config
4. cleared nuget cache

but the build still failed with the same errors.

The project use to be able to build before and no nuget package has changed ever since ( they are also the newest version). I compared the build setting of each (x86/x64/arm). They are almost identical except the Platform target (x86/x64/arm) and Output path.

In the logs, the path of the DLLs are all different only by "-aot" part. They all looks like to be standard library DLLs. By watching the build running, it seems that the issue only occurs starting on the 2nd (x64) configuration.

I have no idea whats going on.

Answer 1

Right Click in Proyect > Manage NuGet Package > Package Sources > Unckeck "Source of package system"

Answer 2

I loaded up the Project in Visual Studio 2022 preview 3.1 and it builds the package successfully again. It looks like to be Visual Studio related issue. Visual Studio 2019 is so unpredictable!
