You didn't ask about this in your question, but I think it's worth pointing out that using a GUID for a primary key is not always a good idea. While it's simple, it can affect performance when a GUID is used in an index. Have you considered using an Identity column that is an integer value instead?

Here are a couple of articles that might be helpful to read.

• Performance Effects of Using GUIDs as Primary Keys (SQL Server Magazine)
• Primary Keys: IDs versus GUIDs (Jeff Atwood)
• The Cost of GUIDs as Primary Keys (Jimmy Nelson's article referenced by the two other articles)
