No target found for method thrown by Caliburn

Question

I'm trying to create an application which allows me to sketch some doodles on the canvas component with the help of Caliburn.Micro for MVVM. When I run the application and click on the Canvas I get "No target found for method OnMouseDown." exception. I defined the method to be called when the MouseDown event is called, but somehow Caliburn doesn't find it.

The project files are available here: SketchingTool.zip

Answer 1

Apparently I wired the application in a wrong way. The ViewModel it was looking for for methods was not the ViewModel they were in, because I mixed the view-first approach with the viewmodel-first approach. Fixing it according to the documentation of Caliburn fixed the problem.
