I keep getting the "Unsupported expression" exception. It seems that the lambda expression (a=>a.PP_EventID==1) is the problem. How do solved this one?
pricepackPersistenceMock.Setup(pricepack => pricepack.Delete(a=>a.PP_EventID==1)).Verifiable();

You should use the predicate inside It.Is<T>() method.
pricepackPersistenceMock.Setup(pricepack => ricepack.Delete(It.Is<TypeOfa>(a=>a.PP_EventID==1)))
.Verifiable();
Update:
eventPersistenceMock.Setup(u => u.Single(It.IsAny<Func<tbl_SBAem_Event, bool>>()))
.Returns(eventlists.Where(a => a.EventMngID == currentevent.EventMngID).Single());
// you can directly return the value
//verifiable is not needed because you set the return value

Ufuk do you know how to mock this one T Single(Func
predicate);? – user335160 Apr 26 '12 at 08:25 -
That's probably a LINQ extension method. You can take a look at this [question](http://stackoverflow.com/q/562129/205859) – Ufuk Hacıoğulları Apr 26 '12 at 08:34

no, I create that method in the repository along with the delete method. – user335160 Apr 26 '12 at 08:39

here is the code eventPersistenceMock.Setup(u => u.Single(It.IsAny

I think there is an error with the code becuase I will always get the first index. – user335160 Apr 26 '12 at 08:39

What do you mean you get the first index? You are calling the Single method, isn't that what you want? – Ufuk Hacıoğulları Apr 26 '12 at 08:47

Sorry, I got it already. What I mean If I try to get the value from the collection having an id=1. I will always get the id having equal 0. But I solved it already. thanks – user335160 Apr 26 '12 at 09:09
