>GUID is random by nature. You can't "sequence" it. Use a identity field (int) if you need a sequencing PK.

A GUID is assumed to be random by many. Randomness is not required by the definition.

>>I am looking for SQL Server 2005 NewSequentialID() equivalent function in C#. I want it because I am using GUID as PK. I am planning to set my PK as clustered index, however, Guid.NewGuid() is generated randomly which is not good for clustered index, Therefore, would like to know if any C# function can do the same thing with NewSequentialID().
