Question

So I declare a random generator in one of my classes like this

static Random random = new Random(DateTime.Now.Millisecond);

and when calling a function in the class even when that function was blank it appeared to block the entire program from running.

static Random random = new Random();

But when I do this it worked as expected?

EDIT with code:

This program is specifically an XNA Game so here is the update function

protected override void Update(GameTime gameTime)
{
    Debug.WriteLine("This happenens");
    EnemyController.generateEnemies();
    Debug.WriteLine("This does not");
}

And here is part of the other class

public static class EnemyController
{
    static Random random = new Random(DateTime.Now.Millisecond);

    public static void generateEnemies()
    {
        Debug.writeLine("This code wont run");
    }
}

As stated in the MSDN documentation for System.Random for the parameterless constructor:

Initializes a new instance of the Random class, using a time-dependent default seed value.

If your instantiation of Random is actually what’s blocking your code, then know that you don’t need to seed it with the time. However, I would look into other possibilities for your code blocking.
