IN VS 2008 i can run .svc but on production IIS 7 i can\'t. I get this error. i am using x64 win.
I run
C:\\Windows\\Microsoft.NET\\Framework\\v2.5.0.303
I had to manually add handler mappings for svc NET 4.0. Somehow they have dissapeared from list of IIS mappings.
I got the idea HERE.
For Win7 machines, the same setting can be made under Conrol Panel-->Programs and Features-->Turn Windows features on or off
Have just been battling with a BizTalk WCF service deployed on Windows Server 2012 IIS. And after testing Everything else, something else shot to mind, Application pools. IF the application pool is set to Classic mode you need to have your httpHandlers under Control, they need to be defined for all file types you intend to use. If you run the application in Integrated mode, IIS will take care of this just fine. Might be good for someone who finds themselves here after googling. :)
