Demonstration of the Mock/regular conflict in Moq

MockGet.cs

private ISomeService Service { get; set; }

[TestMethod, Owner("ebd"), TestCategory("Proven"), TestCategory("Unit")]
public void SomeTest()
{
    Service = Mock.Of<ISomeService>();
    
    //I want to inject it as if it were just some service
    Target = new SomeClassUnderTest(Service);

    //But then I want to configure the meta-behavior around the mock also
    Mock.Get(Service).Setup(serv => serv.Create(It.IsAny<Entity>())).Throws(new Exception());

}
