Hello,

       I recently moved to Visual Studio 2010 and upgraded my website to work with .NET Framework 4. (From VS 2008 - Framework 3.5)

What are things I need to know to improve site speed, readability or memory use?

DivideByZeroException

int SafeDivision(int x, int y)
{
    try
    {
        return (x / y);
    }
    catch (System.DivideByZeroException dbz)
    {
        System.Console.WriteLine("Division by zero attempted!");
        return 0;
    }
}
