WCF - Error 500.21 Handler "svc-Integrated" has a bad module "ManagedPipelineHandler" in its module list"

If you  see this error you havent installed the prerequistes for ASP.NET 4.

Try this

Open Visual Studio Command Prompt
Type the following:
aspnet_regiis.exe -i
Run the command
Try your service again...
Happy Face - it should be working :-)


This basically installs the necessary ASP pieces to get your service up and working!
