These are the most common ways to create an instance of Guid:
00000000-0000-0000-0000-000000000000
):Guid g = Guid.Empty;
Guid g2 = new Guid();
Guid g = Guid.NewGuid();
Guid g = new Guid("0b214de7-8958-4956-8eed-28f9ba2c47c6");
Guid g2 = new Guid("0b214de7895849568eed28f9ba2c47c6");
Guid g3 = Guid.Parse("0b214de7-8958-4956-8eed-28f9ba2c47c6");
