[severity:It's more difficult to complete my work]
[editorconfig.zip](https://aka.ms/dc/file?name=B77aca7d6c96d4e538f3dc506cf7802e1639030338579347246_editorconfig.zip&tid=77aca7d6c96d4e538f3dc506cf7802e1639030338579347246)

I inserted the enclosed file in my .slnx solution (and also in the project, a console app), but the header never appears in the new files neither can be added to existing ones.
The same file worked fine in vs2022.

I similarly have a file_header_template setup in my editor config. When I select “Run Code Cleanup (Profile 1) on Solution” (which includes the “Apply file header preferences” fixer), I see it run on some of my files but not all.

It appears to not apply the file header preferences to the startup project (only difference I can tell). It applies other fixers to these files, and applies the file header in other projects, but this one project is not applied.

(One other thing I noticed after is if I manually trigger the code-refactor with Ctrl+. in a file it does offer the suggestion to add the file header, but it’s with an incorrect/different header???)

This is not the correct file header suggestion, it should be, from my .editorconfig:

# .NET Foundation Header

file_header_template = Licensed to the .NET Foundation under one or more agreements.\nThe .NET Foundation licenses this file to you under the MIT license.\nSee the LICENSE file in the project root for more information.

The other license is not listed anywhere in my repo except on specific file (which needs to retain that license copied from another project).

This issue is currently being investigated. Our team will get back to you if either more information is needed, a workaround is available, or the issue is resolved.

Start by reproducing the behavior with the attached .editorconfig in the .slnx console app, comparing new files, existing files, Code Cleanup, and the Ctrl+. suggestion with VS2022. The issue is done when file_header_template is applied consistently and the configured header is offered and used in each reported path.
