I know how to generate a random number between 0 and 1 using the NextDouble method of the pseudo-random number generator.
var rng1 = new System.Random();
var random1 = rng1.NextDouble(); // generates a random double between 0 and 1.0
And I know how to fill a random byte array using the cryptographically secure random number generator.
Byte[] bytes = new Byte[8];
var rng2 = new System.Security.Cryptography.RNGCryptoServiceProvider();
rng2.GetBytes(bytes); // generates 8 random bytes
But how can I convert the byte-array output of RNGCryptoServiceProvider into a random number between 0 (inclusive) and 1 (exclusive)?
