Where does Visual Studio store file properties?

Question

In Visual Studio there are some file properties such as Build Action, Custom Tool, and whether the file is Content etc. Where are these properties stored? For instance, if I modify the build action for a file, how does Visual Studio remember the new value?

Answer 1

In the .CSPROJ file, wich is stored as xml since Visual Studio 2005 I think. You can Right Click on a project, do "Unload", and then right click again and do "Edit xxx.csproj" and you will see the text directly. If you update it, you can again right click and do a "Reload".
