Hi, i have the following problem: i want to test an abstract class
that contains a method that calls a wcf service. I mock the wcf
service and use a partial mock to mock the abstract class. The problem
is that the wcf service throws a timeout exception when i set an
expectation to the abstract class.The example below replicates the
issue.

Can you explain the purpose of the test? I see that in the test setup (Setup()) you're calling .Open() after setting an endpoint to http://localhost:9090
This seems odd to me, but I don't know exactly what you're trying to test in order to be able to give useful feedback.
If you give me more info I can dig in.

The error you get means that another proccess is running on 9090 port
or that you do not have administrator rights.
The purpose is to test a component that uses WCF services. The
component is an abstract class so i want to mock the abstract methods
as well as the WCF services that it uses.

I don't see that in the tests...I will gladly write the test for you if you give me a scenario...

The code i posted is an example that replicates the problem.
The test scenario is the following. I have the AbstractShape class
which has an abstract method CalculateArea.
The Circle class (which is also abstract) has a CalculateArea
implementation and also an abstract GetRadius method.
The CalculateArea of the Circle uses a WCF service
(ICalculatorService) which contains a Multiply method.
I want to test the Circle.CalculateArea method, so i'm replacing the
ICalculatorService with a mock WCF service.
The problem is that when i set an expectation on the Circle.GetRadius
method and the ICalculatorService.Multiply method
i get a Timeout exception when the Multiply method is called from the
Circle.CalculateArea method.
