The XAML page codebehind (mypage.xaml.cs) has a OnNavigatedTo method in which the VM instance is created and set to the data context like this: this.DataContext = new VM(); In the VM there is a public property of d...

Hello, I have compared two queries which fetch some fairly large data from a database table. For query one I used Linq To Sql and for the other I use passthrough SQL via ADO.NET. I know that Linq To Sql has to do a lot of work behind the scenes, but what is it actually doing? The two queries fetches the same amount of data but the Linq...
