What's wrong with this?

It says "Bummer! Did you throw an exception when the value is less than 0 or greater than 20?" if that helps.

Program.cs 
int value = int.Parse(Console.ReadLine());

try
{
    if (value < 0 || value > 20)
        {
            throw new System.Exception();
        }
    Console.WriteLine(string.Format("You entered {0}",value));
}
catch(Exception)
{
    Console.WriteLine("Value is out of bounds!");
}

There is nothing wrong with your exception throwing. The problem stems from the fact that you don't just throw an exception, you also catch said exception. The task only asked you to throw the exception, and that's all it wants you to do. Catching the exception on your own messes with the code that tries to verify that you threw the exception successfully.

If you remove the try/catch block and just leave the if statement and print command then you'll be able to pass the challenge.
