WCF - EndpointNotFoundException

I have the following scenario: Project A contains 2 interfaces A, and B and two service endpoints, EndpointA and EndpointB, each implementing the matching interface. I have a unit test Project, which uses Cassinini to test the services. I use a proxy I generated with svcutil to create client objects in my unit test. Here is my app.config from the unit test project:

<client>      
  <endpoint address="http://localhost/MyServiceA.svc/MyServiceA"
      binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IRetrieval"
      contract="IRetrieval" name="BasicHttpBinding_IRetrieval" />
  <endpoint address="http://localhost/MyServiceB.svc/MyService"
      binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IModification"
      contract="IModification" name="BasicHttpBinding_IModification" />      
</client>

When I call ServiceA, it works fine. However, when I call ServiceB, I get the following error message:

Test method MyMethod threw exception: System.ServiceModel.EndpointNotFoundException: The message with To 'http://localhost/MyServiceB.svc/MyServiceB' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree.

What's happening? Thanks.

Cassini almost never listens at port 80. You need to find out the port Cassini listens to and make it fixed (using project properties/web and change the default to a fixed port number) and update the endpoint:

 <endpoint address="http://localhost:<PORTNUMBER>/MyServiceB.svc/MyService"
  binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IModification"
  contract="IModification" name="BasicHttpBinding_IModification" />
