How can I retrieve Id of inserted entity using Entity framework? [closed]

Answer 1

There are two strategies:

1. Use Database-generated ID (int or GUID)

   Cons:

   You should perform SaveChanges() to get the ID for just saved entities.

   Pros:

   Can use int identity.

2. Use client generated ID - GUID only.

   Pros: Minification of SaveChanges operations. Able to insert a big graph of new objects per one operation.

   Cons:

   Allowed only for GUID
