This issue has been moved from a ticket on Developer Community.

I have a top-level editorconfig that sets end_of_line = lf. If I begin writing a class such as

class MyClass : IDisposable

or

class MyClass : IDisposable;

and pause my typing, I get the expected 'MyClass' does not implement interface member 'IDisposable.Dispose()'.

I then select the "Implement interface" fix, and VS2022 will generate the rest of the class like this:

class MyClass : IDisposable
{
    public void Dispose() => throw new NotImplementedException();
}

however, the line endings of this part of the file include CRLF, and I see "MIXED" in the bottom right corner of the document.

Note: this only seems to happen in the cases above, where the class is incomplete or ends with a semicolon. If the class looks like:

class MyClass : IDisposable { }

or if the body of the class is already present, then the newly added Dispose method is generated using the correct line endings, and I continue to see LF in the bottom right of the doc.

I am using VS2022 17.14.9 (July 2025)
