How to Ignore specific file from Visual Studio Warnings Analyzer?

Is there anyway to suppress all error codes in one specific file?

Surprisingly I couldn't find this. This is pretty common scenario isn't it?

Documentation describes it seems:

1. we have to disable it line by line or
2. globally across all files.

https://docs.microsoft.com/en-us/visualstudio/code-quality/in-source-suppression-overview?view=vs-2022#:~:text=You%20can%20suppress%20violations%20in,can%20use%20the%20SuppressMessage%20attribute.

Make a section in the .editorconfig file for that given class; specify its file name [{YourClass.cs}] or path [{Folder/YourClass.cs}]in a section and set the severity for all rules to none.

See the All rules scope in the documentation.

[{YourClass.cs}]
dotnet_analyzer_diagnostic.severity = none

You can add this snippet at the very beginning of the file:

// <autogenerated />

This suppresses most warnings on that file.
