Are there any tutorials or examples on setting up foreign keys in the MS EF designer and then passing them through to DevForce EF?
 
I'm relatively new to IdeaBlade and could work with Classic, but I'm not sure how to set up relationships in MS EF.
 
John.

The EDM should pick up the foreign keys defined in the database.  If not, you can define the relationship yourself within the Microsoft EF designer.  Once it's in the EDM, DevForce automatically picks it up.  There is a 100 level learning unit that covers object mapping in WinClient.  Let us know if you have any more questions.

A key used in one table to represent the value of a primary key in a related table. While primary keys must contain unique values, foreign keys may have duplicates. You can find the foreign key tutorial here http://www.eglop.com/Contents/Support/Documentation/Online-Help/Database-Schema-Designer/Contents/Tutorial/ForeignKeyTutorial/ForeignKeyTutorial1.htm
