Hi Paul,
 
Declaring FKs in the Object Mapper will not cause problems even if the FKs are not set in the DB. (In fact, if you don't create the FK for the association, it won't compile)
 
You mentioned you noticed performance decrease when querying.
What kind of query are you experiencing this performance decrease with?
How significant is the performance loss?
 
Silvio.

Does declaring foreign keys within the Object Mapper that are not in the Database (SQL Server in this case) cause a problem?

We had previously NOT delcared foreign keys within our database, but we notice when we add them there is a significant decrease in the performance and IdeaBlade queries.
