Tutorial :Using Generic Types in Window.Resources


I am trying to use Generic Types in Windows.Resources section in XAML code. To attach the notification for a collection of objects my generic collection inherits from ObservableCollection as shown below:

public class PresentationModalCollection<T> : ObservableCollection<T>      {          public PresentationModalCollection(List<T> list) : base(list)          {            }        }    

There is an extension method that returns a ObservableCollection for List as shown below:

public static class ExtensionMethods      {          public static PresentationModalCollection<T> ToObservableCollection<T>(this List<T> list)          {              return new PresentationModalCollection<T>(list);           }      }  

Now, I want to use the PresentationModalCollection in my Window.Resources like shown below:

<Window.Resources>          <LearningWPF:PresentationModalCollection x:Key="customers">              <LearningWPF:Customer FirstName="Mohammad" LastName="Azam" />          </LearningWPF:PresentationModalCollection>          </Window.Resources>  

Of course, the above code does not work. Is there any way of doing the above without having to create a class CustomerCollection which inherits from the ObservableCollection?


Mike Hillberg has some extensions that can help out with it and work pretty well. I agree that creating a CustomerCollection and collection type for each type you wanted to wrap would be overbearing. Sacha Barber also has a solution to use Generics in XAML, but his website seems to have surpassed his bandwidth limit for the moment.
