Are GUIDs timely ordered ? If ORDER BY used with a GUID variable type, will records created lately come late?

Question

Are GUIDs timely ordered ? I mean if you use ORDER BY with a GUID variable type, will records created lately come late ?

Answer 1

A simple LINQPad mockup answers your question:

var dictionary = new Dictionary<int, Guid>();

for (int i = 0; i < 5; i++)
    dictionary.Add(i, Guid.NewGuid());

dictionary.OrderBy(d => d.Value);

Results in:
