Two output file names resolved to the same output

Question

Recently I created new Form called WorkersScreen. When I try to run the project I got this error:

Error 1 Two output file nam

Answer 1

In my option, help delete one *.resx for every form where the error raised

Detail INFO

In our project we have 6 *.resx for every form for localization (DE,GB,SK,RU,SRB) and if i delete (from VS) FormName.sr-Latn-CS.resx than the error disappeared. If i try deleted FormName.en-GB.resx it did not help. Error disappeared just for delete sr-Latn-CS.resx (maybe a designer can not solved two - ). I first saw this error when I migrated project from VS 2010 Win 7 to VS2010 Win 10.
