Publish Single File (Release) fails for WPF .NET Core 3.1 application

Question

I\'m trying to publish a WPF Application (to a folder) targeting .NET Core 3.1, using Publish Single File, targeting win-x86. The application publishes fine for Debug, but fails

Answer 1

I am getting the same issue, but I think mine is related to the project not even being able to build when I set "PublishSingleFile".

I added a comment to their github issue post, assuming that it's a bug on their end since .net core 3.0 is publishing for me fine.
