persistence - Where to save application data in .NET application

Question

My application is something similar to a Contact Manager. Let's say a user can enter contacts with their addresses. I have the code and technology to save my contacts to a file. But where do I save that file?

Considering this is a .NET application running on Windows. Should my file end up in the AppData of the users folder? Should I use the Isolated Storage (as mentioned here)? Something else? What's the recommended practice?

Answer 1

I ended up using the solution Patrick suggested:

Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)
