I'm sure I'm doing something wrong, but I'm having trouble getting out of the gate with Model First.

Created a few entities and added primary keys and unique contstraints. Validation shows no errors.

When I generate the DDL, I get no primary keys, and no unique constraints in the generated code. I see these empty areas of the DDL:

-- ----------------------------------------------------------------------------------------------------------------
-- Primary Key constraints for schema 'dbo'
-- ----------------------------------------------------------------------------------------------------------------
-- ----------------------------------------------------------------------------------------------------------------
-- Unique constraints for schema 'dbo'
-- ----------------------------------------------------------------------------------------------------------------

Am I missing an obvious setting?

Ah, of course I figured it out five seconds after I posted.

I need to generate an update script after generating the create script.

Ok, now I'm really confused. After generating the update script, I can no longer generate another update script (no changes, so that makes sense).

But now I generate the create script and it works like I originally expected. Should I be able to generate the create script at any time, and get the full creation of my database? Or if there are pending changes, do I need to generate a create and then an update?

It might be that I'm just not understanding the cycle of working model first.

Ok, an update in case anyone out there runs into the same thing.

I wasn't clicking the right validation button--I needed to click "validate and adjust relational model," which I must have done between generating the create script and the update script.

The section of the manual I was following correctly says this, so it's not a case of RTFM, it's a case of UTFM (U = "understand").
