Delegate Command and Routed Command

Question

What is the Difference between the Delegate Command and Routed Command?

I read some article that says use Delegate Command on MVVM instead of Routed Command.

So What are the advantages of Delegate Command over Routed Command when we use MVVM?

Answer 1

Some advantages of using a DelegateCommand (a.k.a. RelayCommand) are:

1) Requires less XAML/code to support them (don't need CommandBindings)

2) Command implementation code can easily be written in ViewModel classes

3) They do not take a dependency on the UI element tree to work properly, which also helps improve performance

Since a lot of third-party UI controls use routed commands, most developers end up using routed commands when taking a dependency on those controls.

If you end up needing to use routed commands, check out my Using RoutedCommands with a ViewModel in WPF article to see a way to simplify things.
