Rationale

It is sometimes desirable to generate random numbers as inputs to tests. This works nicely for the majority of the primitive types, but not for long/ulong.

As such, I propose a method be exposed that allows the generation of random 64-bit integer values.

Proposed API

public class Random { public virtual long NextInt64(); public virtual long NextInt64(long maxValue); public virtual long NextInt64(long minValue, long maxValue); }
