Question

I am using EF4 in VS2010 and I have the following code:

MyEntity entity = null;
entity = MyEntity.CreateMyEntity(0);
context.MyEntities.AddObject(entity);
context.AcceptAllChanges();
context.SaveChanges();

The problem is that AddObject() is not adding the object to the collection and I just can’t figure out why. What happens when I step through the code is that it gets to the first property, “CityId” which is of course null and then it seems to just return from there… like it had a problem with the property being null. The only non-nullable field in my database (MSSQL) is the Id column, which is an identity column… I am quite perplexed. Please help!

Thanks in advance!

You are not supposed to call accept all changes method.
