How to handle App.XAML events in Main.cs?

Question

I would like to know how I handle events that I set in my App.XAML file in a standard WPF configuration. I have a button in my App.XAML file and I would like to add an event handler which is located in my Main.CS file.

Example code:

xmlns:local="clr-namespace:MyApp"

<Button Click="Myhandler" />

Even though App.CS and Main.CS both share the same namespace I get an error saying that my handler does not exist. How can I set the context in the right way?

That's because the class of your App.xaml is MyApp.App :

<Application x:Class="MyApp.App"
   ...
>

xmlns:local="clr-namespace:MyApp" is just like adding a using local = MyApp; line to the beginning of ac# code.

You have to create your event handlers in MyApp.App. but if you're concerned about the Right way to do it you should use Commands instead of event handlers.
