Why can't I use NEWSEQUENTIALID() as the default value for my column? I'm trying to create a  table in Management Studio and after reading about the new (from SQL 2005 on) NEWSEQUENTIALID() function, thought I'd give it a go.

This is what I'm doing:



But it's not letting me. The error message I get is:

'FormTemplate (Forms)' table - Error validating the default for column 'FormTemplateId'.


Am I missing a trick here? I'm definitely running SQL Server 2008 R2.
Use CREATE TABLE, not the GUI.

This is a bug in SSMS, already reported here as well as here on Connect.
