The Take<TSource>(IQueryable<TSource>^, Int32) method generates a MethodCallExpression that represents calling Take<TSource>(IQueryable<TSource>^, Int32) itself as a constructed generic method. It then passes the MethodCallExpression to the CreateQuery(Expression^) method of the IQueryProvider represented by the Provider property of the source parameter.
The query behavior that occurs as a result of executing an expression tree that represents calling Take<TSource>(IQueryable<TSource>^, Int32) depends on the implementation of the type of the source parameter. The expected behavior is that it takes the first count elements from the start of source.
