What is a .csproj.user file?

The .csproj.user file is a supplemental configuration file used by Microsoft Visual Studio for .NET projects. While the primary .csproj file contains the core project structure, build configurations, and source file references that are shared among all developers on a team, the .csproj.user file is intended to store local, user-specific settings. These settings typically include preferences that should not be committed to version control systems like Git, such as specific debugging paths, local web server ports, command-line arguments for debugging, or the state of open project windows. Because these files contain machine-specific paths and personal preferences, they are generally excluded from source control to prevent conflicts and broken builds when other developers pull the code. If a .csproj.user file is deleted, Visual Studio will simply recreate it with default settings the next time the project is opened, making it a transient and non-essential file for the actual compilation of the software.
