.editorconfig Errors/Warnings only showing for files that are open

Question

I set up .editorconfig preferences for naming, and I want to see them for all files in our solution, but Visual Studio (2019 16.4.5) only shows the warnings / errors (as defined) If I have the file open in the editor, not for all occurrences in all files, like I want.

How can I see all occurrences of naming rule violations across all files in the solution?

Answer 1

In Visual Studio go to

Options -> Text Editor -> C# -> Advanced

and check

• Enable full solution analysis
• Use .editorconfig compatibility mode

Then restart VS and rebuild solution
