How to debug into WFC code?

Hi,

I can load symbols for WFC (e.g. System.ServiceModel.dll), but when I go-to-declaration on a type (e.g. System.ServiceModel.Channels.CommunicationObject) I only get all the signatures but no method bodies.

Whereas when I do the same on e.g. Boolean then I get the source code and everything.

Some output from the Output window:
