Add a file header to your C# files with the help of .editorconfig

The file_header_template property in .editorconfig allows you to automatically add a license or custom header to every new C# file you create. This is especially useful for maintaining consistent file headers across your project.

How to use file_header_template

To enable this feature, add the following configuration to your .editorconfig file:

[*.cs]
file_header_template = Copyright (C) 2020-2025 Our nice project.\n\n{fileName} is licensed under MIT.

Where the {filename} is a placeholder for the name of the file your header is placed into.

The use of the file_header_template property will save you time by automating the addition of headers and is a perfect way to enforce licensing or documentation standards in your repositories.
