Recently I created new Form called WorkersScreen. When I try to run the project I got this error:
Error 1 Two output file nam
I had the issue and it was caused because I had a partial class of a custom control.
I had accidentally created a .resx file for the partial
I think I did this by hitting shift F7 on the partial class and producing the empty designer form.
Removing the .resx file on the partial class resolved it for me. I was using version control and it was showing that it was a new file.
Hope this helps
