I have the following code:

	int? i1 = null;
	int? i2 = 3;
	string s = i1.ToString();
	Console.Out.WriteLine("s = '" + s + "'");
	Console.Out.WriteLine("i1 = '" + i1 + "'");
	Console.Out.WriteLine("i2 = '" + i2 + "'");

On the 3rd line R# warns me about a "Possible System.NullReferenceException". However, the program runs fine.

Note that Nullable<T> type in itself is a value type and thus can never be null. Only the Value property or a cast can result in an InvalidOperationException.
