I’ve used the Visual Studio 2010 Express All-In-One to install Visaul C# and Visual Web Developer.
Once I opened Visual C# and tried to create a WCF Application, I couldn’t find it.
After looking on internet I found a tip to do it on stackoverflow.
I have done exactly like the guy explained, and now I have WCFServiceProject.

Now everything seems to be correct, but when I try to create a WCF project I get this error

Any ideas ?
I don’t think you have the option to create a WCF Application in Visual Studio 2010 Express.
