c# - What is the .vs folder used for in Visual Studio solutions?

Question

What is the .vs folder used for exactly? It gets created at the base folder of my solution. I can see some hidden files and different files appear for different projects. I'm having a hard time chasing up official documentation on it.

Answer 1

Even though there is no specific documentation, there was a similar question here

Usually, .vs folder is required by Visual Studio to store opened documents, breakpoints, and other information about state of your solution. which means It contains typical files like,

• Temporary caches used by Roslyn for IntelliSense.
• IIS Express applicationHost.config file.
• Many other possible files (you are welcome to edit this answer to include what you know of).
