I thought I had implemented MVVM. Then I read your article which states most people "think" they implemented MVVM. In reality, they did not. Thank you. 
No, it was a decent read. I still want real layman basics though. I could not find them here at CP.

Can you link the particualr article? I'd like to read it (cause I think I've been implementing MVVM and would like to be sure!) and couldn't find the right one.

I think I read most of Sacha's stuff ages ago when I started looking at MVVM - it was certainly most helpful - but I;m interested in what you think you had that wasn't MVVM?

Well, I saw a couple of things. I was still doing it with kind of MVP/MVC mindset. Another thing I did was I was sending across a control to view model (just the PasswordBox) and was struggling with showing some dialogs and reporting progress on screen.
Remember, I am totally new to WPF World. I just thought I had implemented MVVM[^]. A little reading on web suggested I have probably done it. The solution structure was not like MVVM but functionally, I appeared to be one.

OK - thanks.
When I started looking at MVVM I was new to WPF too - and read tons, but really had to do some hands on development for it all to gel.
I ended up not using any framework, but rolling my own, which is sort of am M-V-VM-C .
I wrote some articles about it if you are interested - see my sig.

One small thing. The article slightly leads you astray on something. MVVM is not a presentation pattern, it's an architectural pattern. That does have implications.

Exactly. I have had this realisation now. I am planning to halt writing code as of now and work on a small POC to get to know things better. Another reason for the pause is that I am making heavy use of DLR and I have started to believe that the way I had designed and the way I am implementing it is going to result in:
1. Large start up time.
2. Complex caching mechanisms involved.
3. More casting and conversions that I can live with.
4..n: Many more.
Need to get back to drawing board.

I don't see how using the Docklands Light Railway has any effect - although the start up time could be a little longer!

MySql? No thanks. I'd rather place my trust in Oracle.

Some days you are the Roadrunner some days you are the Coyote, I have had a very awkward 'thing' this week as well as moving/not moving/production delivery to make (finding the tools for it). The thing was to improve/debug a test rig written in an unpopular language (look at my previous posts in the lounge to figure out what) which I am being forced to use. I asked a question which reflection could have been better worded and got a reply from Sergey Alexandrovich Kryukov of basically rtfm which was not a bad idea, As I managed to hide for a day and a bit and get the darn thing working...no info, badly written & useless commented code. Never mind I get to play with the next instrument next week...
