Question
I am writing a C# program that uses LINQ. This is what it is supposed to do:
Take a sequence of integers
Remove all odd integers, leaving only even ones
Squares each integer
Removes any resulting integer that is greater than 50
But I am getting a System.Linq.Enumerable+WhereEnumerableIterator`1[System.Int32] error. What is causing it and how can I fix it?
