C # Extension Methods on PocketPC Windows CE

Are there extension methods within CE? I have an extension method for a string that works fine in a Windows forms project, however it will not be embedded in a PocketPC application.

I realized that it would be easy to find out, but I could not find information about extension methods on PocketPC.

Change: . Oh, that was my mistake. I wrote an extension method in Visual Studio 2008, however the PocketPC project was compiled in Visual Studio 2005, which I did not understand. It’s good that in an hour of my life I will never return. Thanks everyone for the answers anyway.
