Ok, thank you. But if i set that you said, I got an exception.
I'm sorry, because i use DCSQLite in this project. Sorry again.
So, I have a table, called Folders. In this table FolderId field is an Auto increment field.
My example code:
Folders nf = new Folders();
nf.FolderName = "test folder";
EnochDb.AddToForms(nf);
EnochDb.SaveChanges();
The line "savechanges" given an exception (there is exception after my post, because it's too long).
Also i got an exception, when i set FolderId by manualy before rows add and save.
When i don't set that you said, and set FolderId manualy, the savechanges method don't give an exception.
I found StoreGeneratedPattern at the tables and views/Folders/folder_id in EntityDeveloper.
