System.NotSupportedException: Unsupported expression: p => (p.UserProfileId == 1)

Question

I have a test that uses System.Func expressions. It should be pretty straight forward, but the test keeps on failing.

Test:

  [TestMethod]
  public v

Assuming that you're using Moq and that someDataMock is a mocked object, the problem is with the setup. Try this instead...

someDataMock.Setup(s => s.GetUser(It.IsAny<Func<User, bool>>()).Returns(userProfile);

That should work, but you might want to make the mock a little bit more restrictive in what callbacks it accepts, depending on the nature of your test.
