Why i need to add so much code for such simple functionality like handling ui event etc. MVVM is also often called 'programming for masochists' :) But seriously there are many reasons why this is good. Its hard to create all this infrastructure but once its there you can just use it but it gives you separation from UI, testability, you can easily replace parts of functionality because its decoupled etc. But if you feel this is not your cup of tea simply skip it and do what many programmers do: just write it... But don't forget: usually when you 'just code' without plan or patterns later you pay the price when you need to maintain this. Good luck! Yes very often i ask myself the same question.

Why do i need to include the MVVM light toolkit or BLEND sdk to do what takes one line in code behind...where or where is the benefit other than adhering to the MVVM dogma ? Any command, method , event in the view should be able to be bound in a single line to a corresponding method, property etc in the view model without creating a mini project.

I did find an error however and thought you would like to know. When I tried to run a command that implemented a canExecuteAction I encountered a casting error. This is probably better explained in code. I have included my fix as well. Here is the Pastie. http://pastie.org/1259256 Great post thank you very much, just what I was looking for.
