Why is Visual Studio not able to open .csproj files?

.net visual-studio-2008 xna xna-3.0
Mil picture Mil · Dec 4, 2008 · Viewed 61.6k times · Source

I have the odd problem that I am not able to open the properties of my .NET projects in Visual Studio. If I try to open it by clicking on the Properties tree node in the Solution Explorer I get the following message:

There is no editor available for '....csproj'. Make sure the application for the file type (.csproj) is installed.

If I try to open the project properties by the main menu nothing happens at all.

I already tried to reset the Visual Studio settings by command line and a repair installation but nothing helped so far.

I use the Visual Studio 2008 in version 9.0.30729.1 SP including the XNA Game Studio 3.0, ReSharper 4.1 and Visual SVN 1.5.1.

It is occurring on all my projects and seems to be a local issue because my co-workers do not have this kind of problem.

Help is much appreciated!

Thanks, Michael

Repair installation doesn't worked as I mentioned in my question. The problem was solved by using the command line with

devenv /ResetSkipPkgs

BUT after that I had to reset some of my Resharper settings.
