I just upgraded my Moq Nuget reference from 4.13.0 to 4.14.7 and my tests started failing. I tracked it down to this piece of code that sets up mocks for the DbSet. I could not determine what Moq is expecting. I did not play around with other versions between these two to know which one it started breaking on.

public static Mock<DbSet<T>> CreateDbSetMock<T>( IEnumerable<T> elements ) where T : class
		{
			var elementsAsQueryable = elements.AsQueryable();
			var dbSetMock = new Mock<DbSet<T>>();

			dbSetMock.As<IQueryable<T>>().Setup( m => m.Provider ).Returns( elementsAsQueryable.Provider );
			dbSetMock.As<IQueryable<T>>().Setup( m => m.Expression ).Returns( elementsAsQueryable.Expression );
			dbSetMock.As<IQueryable<T>>().Setup( m => m.ElementType ).Returns( elementsAsQueryable.ElementType );
			dbSetMock.As<IQueryable<T>>().Setup( m => m.GetEnumerator() ).Returns( elementsAsQueryable.GetEnumerator() );
			//dbSetMock.Setup( m => m.Include( It.IsAny<Expression<Func<T, IQueryable<T>>>>() ) ).Returns( dbSetMock.Object );
			dbSetMock.Setup( m => m.Include( It.IsAny<String>() ) ).Returns( dbSetMock.Object );

			return dbSetMock;
		}

Hard to say for sure without being able to test with an actual repro code. The most likely culprit is, once again, recursive verification. As a workaround, try replacing all .Returns(...) in your helper method with .Returns(() => ...).

Closing due to not getting any response. Not much to be done without repro code.
