How “good” is this method for generating random numbers?

Question

I was searching on google for RNGCryptoServiceProvider with examples on how to limit the range between Max and Min, and still get an even distribution. Before I used modulo oper

There is no point in using an encryption class random generator to seed a regular random generator. (By the principle of the weakest link...) Just use a single instance of the random generator, and reuse it:

private static Random rnd = new Random();

public static int GetRandom(int min, int max) {
  return rnd.Next(min, max);
}
