"project type is not supported by this installation"


  • Just installed VS2010 and trying to do some REST web services.  When I try to create a new project of type "WCF Rest service Application" (which I downloaded from the online template gallery), I get "the project type is not supported by this installation".  Interestingly enough, same error is generated when I try to create a project of type "WCF Service Application" (template which ships with VS 2010).

    Also came across an EXCELLENT tutorial @ "", which has downloadable code.  Guess what, same error.

    I am using VS2010 on Win7 x64.  IIS is not installed on the machine - could that be an issue?  I assumed it would use Cassini while in VS.

    Thanks for any help,


    My apologies if this is not in the correct forum.  I dont think its related to the WCF, but hey, if I was an expert, I wouldnt be asking all of you, right?  :-)

  • What edition of VS2010 are you running?

  • I have the same problem. I got "the project type is not supported by this installation" when I tried to create a new "WCF service" project.

    I don't have problems when I create a "WCF library" project.


    My configuration is:

    - Visual Studio 2010 Professional (c#, c++,

    - Windows 7 Home Edition


    I installed Visual Web Developer 2010 express and I was able to create the WCF service project.


    Please help me!

  • Try repairing the installation and/or running in safemode to ensure nothing is conflicting with it.

  • Try opening your Visual Studio project files in notepad, Remove the ProjectTypeGuids, save and open again. It helped us resolve our issue, though our scenario was different. We were trying to open VS 2005 project file in VS 2010.
