Following works as expected: VS Studio 2019 tested with professional and community.

  • Create new APF App (.NET Framework)
  • Open properties Folder
  • Change Resources.resx to public
  • Create a new resources file (Resources.de.resx)
  • Build

Compiles as expected

Following does not work:

  • Create new APF App (.NET Core)
  • Create a Resources Folder
  • Create a new resources file (Resources.resx)
  • Change it to public
  • Create a new resources file (Resources.de.resx)
  • Build

Tested it on 3 different machines with VS 2019 professional and community

Compile Errors:

Error Custom tool PublicResXFileCodeGenerator failed to produce an output for input file 'Resources\Resources.de.resx' but did not log a specific error. WpfApp4 C:...\source\repos\WpfApp4\WpfApp4\Resources\Resources.de.resx 1

In VisualStudio 2019 in an asp.net core 3.1 webSite project (using Globalization), I faced this issue when I used an existing resource file.

To solve the issue:

  1. Created a new Resource.resx. (Using Add>New Item...>Resorce File.resx .
  2. Copy all contents of the first file in the new file (Copy all three columns).
  3. Delete the old file.
  4. Rename the new file to the intended name.

It worked for me. I wish it works for you too.
