这个 WCF ChannelFactory 类型的怪异怎么可能？

Question

ChannelFactory<T> factory = ...;

var channel = factory.CreateChannel();

channel.GetType().IsInterface; // true -> what? an instance of interface?

channel is IClientChannel; // true
channel.GetType().GetInterfaces(); // empty array -> so does it really implement IClientChannel or does it not?

Please take a look at the provided code sample.
I know that WCF dynamically compiles __TransparentProxy but how can it hide a type of channel so that object looks like an instance of an interface?
How could one obtain real type of channel and list of interfaces it actually implements?

Answer 1

AFAIK

channel is an instance of an interface, not a class. At least the way the code sees it. Though there is, presumably, an actual class there, in this code it's considered something like an instance of an interface.

That interface doesn't implement other interfaces so GetInterfaces() is empty.

About how to get the actual class behind the interface - that should be a separate question. (And, I don't know how to do it.) But check first - it looks like it's been asked before here.
