Hi,
I'm currently using datasets for my cached data, however I'm looking at Ling to Sql.
In my existsing object library I would do something like this to create a collection:
public class MyCollection : Collection<MyClass>
{
}
How is this replicated in the designer?
Thanks
John

I cannot understand what you mean by using the above codes？This is not Linq to SQL but Linq to Object。And Collection has referred a List<T>，So you can use that directly。

class ObservableT : ObservableCollection<T>
public ObservableDriver(DataContext DataDC)
foreach (T in DataDC.T)
this.Add(ex);
//How to use
DataContext = new DataContext();
ObservableT table = new ObservableT(TEntity);
You can expose it as Static
