Lazy Load in Entity Framework 3.5
I want to check null control in entity framework which uses 3.5 version. I have an example like below.
Now , I have multiciplity 1 to Many in this situation it gives error whe Unit table does not have relational record because it excepts the record if i change mutliciplity 0 to 1 it works well. My Problem is i dont want to change mulitipclity, it become 1 to Many, but i can check Load() method is null ,if it is null i do somejob ..
How can i do?
