I am trying to open a project in VS 2010, but i am getting an error while opening it. Can any one tell what this error means?
The Project is under
I'm assuming it means you are using the express version, and in that you don't get integrated source control.
Need more info like confirming the above and knowing what sort of source control the project is in.
This means that:
But, if you want just run the project, or just see the code, or jsut do not want to collaborate with it, you should ignore this message.
This means that the solution you opened is under version control, like Team Foundation Server (TFS). To work with the versioning features you need a special version of visual studio.
As it seems (assumption based on the error message) you can use the source from the project, you can build and start the programm, but you cannot commit any changes you made to the versioning repository.
The wikipedia page about TFS explains pretty well what TFS is about: http://en.wikipedia.org/wiki/Team_Foundation_Server
If you working with the code for yourself, it shouldn't be a problem. If you work on a team project, using TFS as versioning system, you would have to upgrade to another VS version.
Maybe this stack overflow thread can help you a bit: Connect Visual Studio 2010 Professional to TFS
The solution to this problem is to locate your Visual Studio 2008 development environment executable at the Command Prompt (it’s at C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe by default) and type:
devenv /resetskippkgs
Possibly, this will help u, check this out... "the project type is not supported by this installation" error

You are using Visual Studio Express, which does not support add-ins, and therefore does not support source control add-ins.
There's a similar question over here: Source Versioning for Visual Studio Express

was corrupted. Deleted it all works now.
