I have tested the code snippet that you have provided and it works as expected. The issue that you have described is related to the fact that the Mock object is not a real object, but a proxy object. The proxy object is used to intercept the calls to the mocked object and to set the expectations. In order to return the Mock object, you need to use the MustReturnMock() method of the RecursiveMockingBehavior class. Please find the sample code below:Please let me know if this helps.Regards,StefanTelerik24Hi,Thank you for your reply. I am afraid that you cannot use the MustReturnMock() method in the Arrange method. The reason is that the MustReturnMock() method is used to set the expectations for the mocked object. The Arrange method is used to set the behavior of the mocked object, which means that you cannot use the MustReturnMock() method in this method. Please let me know if you have any further questions.Regards,StefanTelerik
