I was receiving this error when working with a WCF service written in C#. A few people online were posting that they added a AspCompatibility tag in their web.config file and it corrected the issue. This error in my case was due to my usage of MEF as an IOC container.

To fix the error I just had to ensure that the [Export] attribute was added to the top of my service class. When my service host started and was called it was trying to compose the service using the IOC. Without the [Export] attribute the class was not available in the container.
