Learning MVVM from the ground up for building real-world software

My two MVVM video series` on YouTube have become very popular, and I have every intention of continuing getting more information out there on MVVM through my Enterprise series. If you haven’t had a chance to check out the videos, here is the full list below.

MVVM Questions and Answers – http://youtu.be/j8Fke2cUTTc

I want to thank everyone who has followed my series and provided feedback. It has emboldened me to ensure I provide quality content and continue the effort of producing videos. MVVM in of itself is a simple concept, but a lot of questions stem from people trying to build real-world software, and finding material for that can be difficult. From the basic stock ticker demos to simple CRUD applications and Msdn articles, none of these really actually demonstrate a full stack MVVM application using dependency injection, service locater’s, messengers, unit testing, mocking; basically the full stack. This is what I intend to do through the enterprise MVVM series. Maybe I will write a book at some point. Who knows. Right now though, I’m enjoying producing the video content.

I also just ordered new sound equipement, the RODE PodCaster microphone, as my Blue Yeti one sort of, well, fizzled out I guess. Bummer, but looking forward to the new one already. Anyhoot, check out the videos if you haven’t already. And again, thank you to my followers!!

Enterprise MVVM in WPF: Adding Data and Business Layers using Entity Framework

Second video in the Enterprise MVVM in WPF series where I demonstrate the practice of adding a data layer and business layer using Entity Framework and test driven development (TDD). Learn how to make a unit of work business context that you can use to encapsulate your business rules and logic, but still be able to go a layer down to entity framework.

Enterprise MVVM in WPF: ViewModel Validation using Data Annotations

I finally had some time off from my busy work life to produce a few WPF MVVM videos on my YouTube channel. It is a bit of a relief to finally get some content up for you guys again. Prior, I believe the last video I had done was a bit over a year ago. The video is the irst video in a new series on what I consider to be enterprise MVVM development for WPF. We will begin covering practical application development scenarios that you will encounter in the real-world, and focus on building high quality, low maintenance, enterprise solutions.

Video Notes:
– I apologize for the low audio, the new microphone (Blue Yeti) picks up pretty much all background noise, and my desktop PC is very loud. I will be looking into ways to resolve this, and if anyone has recommendations please let me know.
– When I originally created the projects I had Visual Studio set to .NET 4. If you are using Visual Studio 2012 or 2013, make sure you set your projects to target .NET 4.5 or .NET 4.5.1.
– There are two parts where the audio may seem like it was edited, and this was true. Sometimes noise from other people makes it into a video and I do my best to edit it out without ruining the video content.
– The downloadable source code will be much cleaner than what was demonstrated in the video. I will be focusing more on the approaches in my videos, and cleanup can always come later.
– The downloadable source code will also contain many more unit tests, including some unit tests for the view models that we were not able to do in the screencast originally.

Thank you everyone for all your support! I have been listening to the questions and feedback in the comments, and paying attention so that I will be focusing my attention on the questions and topics you guys are asking for.
