I am trying to work out an example from ".NET Domain Driven Design with C#", which contains a code example where you can see declared some attributes of type DelegateCommand.

Now, I've tried googling it up, but I can't find its reference anywhere on MSDN (actually, I found this article, but not DelegateCommand's article itself).

Is the DelegateCommand something that's part of WPF or is it just something created in the book?

If it's part of WPF (or any other MS product), in which assembly/namespace is it?

Thanks

Did you go through this question on so?

Seems I already have this installed, since I'm using Visual Studio 2010. In which assembly/namespace is it? Why is that there seems to be no MSDN documentation on it?

DelegateCommands is a custom implementation of ICommand. Delegate command was introduced(correct me if I am wrong) in prism(Composite Application framework) - http://compositewpf.codeplex.com/

You can use that or you can implement your own as done here -

The DelegateCommand is not (yet) part of the standard library (BCL).

It is part of WPF command-binding for MVVM.

Until we get an 'ófficial' MVVM template in VS, all the MVVM examples/toolkits define it somewhere themselves. Not always with the same name or in the same place.

I've found it called RelayCommand (I think that's the original name, to be honest). Please see here:

Hope that helps!
