LINQ-to-SQL and SQL Compact - database file sharing problem
- by Eye of Hell
Hello.
I'm learing LINQ-to-SQL right now and i have wrote a simple application that define SQL data:
[Table( Name = "items" )]
public class Item
{
[ Column( IsPrimaryKey = true, IsDbGenerated = true ) ]
public int Id;
[ Column ]
public string Name;
}
I have launched 2 copy of application connected to the same .sdf file and tested if all database modifications in one application affects another application. But strange thing arise. If i use InsertOnSubmit() and DeleteOnSubmit() in one application, added/removed items are instantly visible in other application via 'select' LINQ queue. But if i try to modify 'Name' field in one application, it is NOT visible in other applicaton until it reconnects the database :(. The test code i use:
var Items = from c in db.Items
where Id == c.Id
select c;
foreach( var Item in Items )
{
Item.Name = "new name";
break;
}
db.SubmitChanges();
Can anyone suggest what i'm doing wrong and why InsertOnSubmit()/DeleteOnSubmit works and SubmitChanges() don't?
