AddressFilter mismatch in EndpointDispatcher

I have a WCF web application that uses the WCF class library. My project is a WCF web project, and I'm hosting myself.

My problem is that all my web service methods hang with:

And "Unable to automatically go to the server ... etc.".

Error (not very useful):

The operation has timed out

When I call the same method (s) using the WCF test client, I get the correct answer and everything goes smoothly.

So, something is wrong with my web application.

Following a similar entry, I used the trace viewer. I get an error message:

 The message with To 'http://localhost:8731/Design_Time_Addresses/Authentication/mex/mex' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver EndpointAddresses agree.

After reading the related post, I tried to add:

 [ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]

And recompiling my class library and updating my services to no avail ... still freezes.

I tried to add both my web service and my web project as launch projects, but I still cannot enter the code. I also have all the relevant DEBUG attributes in Web.config and App.config.

Are there any suggestions?

Not knowing what your configuration looks like, it's hard to say what's wrong. However, why does your URL have / mex twice in it? Are you sure right?

From my experience, the mex / mex error occurs when I update a service link in Visual Studio. I came to the conclusion that this is just part of how Visual Studio determines how to update a web service before
