Publish cannot find compiled output of local project dependency

alecxvs commented 4 years ago

I have a solution that consists of two projects:

"WindowsApp", a netcoreapp3.1 WPF project which depends on "Lib"
"Lib", a netstandard2.1 library (with a netcoreapp3.1 target in order to use EF Core Tools)

And I'm using Visual Studio 2019

I'm trying to publish my application as a single file executable, but publish keeps failing:

Metadata file 'C:\repos\MySolution\Lib\bin\Release\netstandard2.1\win-x86\Lib.dll' could not be found

It seems to be looking in bin\Release\netstandard2.1\win-x86\ for the library instead of bin\Release\netstandard2.1\.

This seems to present an identical error but I'm not sure the root cause of the error was ever discovered: https://github.com/dotnet/aspnetcore/issues/11088

Same issue here, with similar project structure. VS for Windows version 16.8.2 .NET Core SDK 3.1.402

Same issue with VS2022 and NET6. I can work around the errors by manually copying the files to the requested location.

Attention here would be highly appreciated.

dotnet / sdk
