Simply the best format to deliver such a training:
The learning material is succint: it is of high quality, to the point and easy to read.

You can read the code and the explanation sided by, which is just the best way to get introduced to the word of WPF+MVVM applications.

I hope many similar training materials will surface soons, because this far better than watching videos/reading long books.

In addition to the great experience another very practical aspect is that you have great quality sample code that you can use out of the box start building your own application.

Thanks for this training material.

Thanks Karl, this was awesome and informative. I hope that you continue to provide extensions that make learning new features to .NET much easier.

This is just excellent!

I am a Trainer for some years and I can only recommend this to anybody who wants to learn how MVVM is functioning and and what are the thoughts behind.

You know what you are takling about and how to enable others to understand the subject practically.

Many Thanks, Karl

When will Prism in the box be available?

by NMackay | October 20 2011

Excellent MVVM training and guidance, there are so many misleading MVVM articles out there and Karl's articles are clear and concise. It would be nice if the samples were in VB.NET too, I've been looking at Ocean which seemed like a nice light framework, Prism seems too much although you don't have to use the whole framework, I think lot of people looking at the MVVM design pattern for the 1st time get caught up in the framework element.

Is the version of Ocean (V3) planned for 2010 going to be released or have you decided to leave Ocean as it is, I gather your involved in Prism now ?

Anyway, keep up the great work, MVVM is a nightmare TBH, I thought evaluating ORM's was a pain but MVVM has been driving me nuts :) although I recognised a while back that code behind with WPF for large scale LOB apps can become un-maintainable although I don't see why code that purely is for UI control extension (such as a Telerik carousel which requires code behind to get the behaviour you want) would ever need to be in the ViewModel.

    • Could post a download of the vsix for vs2012 and/or 2013? Thanks.
    • Sorry Bill, but this only works with VS 2010.  It takes a dependency on Feature Builder that Microsoft didn't move to VS 2012 and later.
  • Interaction Trigger errors

    • Fired up a new in the box project but the initial build failed with the following errors...
      Am I missing a pre-requisite or do i need to update my copy if prism which i downloaded and installed with the intention of learning but have done absolutely zip with!!!
      Error	3	The tag 'Interaction.Triggers' does not exist in XML namespace ''. Line 38 Position 26.	C:\WPF\MVVMTraining1\MVVMTraining1\Acme Common\Acme.Prism\InteractionRequest\ConfirmationLocalModalInteractionDialog.xaml	38	26	Acme.Prism

    • Have you installed the Expression Blend 4 WPF SDK?
      It's a free download.  See my blog post here:
    • Hi,
      I have the exact same problem. Get the same errors on first build. 
      I have installed the Expression Blend 4 WPF SDK. 
      What do you think is wrong?
    • Hi Karl,
      thx for your cool stuff. I have the same problems. But installing "Expression Blend 4 WPF SDK" and a rebuild of the project map solve the problems.
      thx alot
    • Manually adding/updating the failing references to point to the libs in the Microsoft SDKs\Expression\Blend folder helped me.
    • installing "Expression Blend 4 WPF SDK" and change 2 references 
      C:\Program Files\Microsoft SDKs\Expression\Blend\.NETFramework\v4.0\Libraries\Microsoft.Expression.Interactions.dll
      C:\Program Files\Microsoft SDKs\Expression\Blend\.NETFramework\v4.0\Libraries\System.Windows.Interactivity.dll
      then solve the ploblems
  • VS2012

    • Hello Karl, could you please add support for VS2012
    • Open the vsix file with 7 zip. Open the extension.manifest file and locate the following line:
        <VisualStudio Version="10.0">
      Change <VisualStudio Version="10.0"> to <VisualStudio Version="11.0">.
      Then use 7-zip to zip the file back. Change the extension to vsix. You now should be able to install the extension.
  • .MHT file not readable by IE
    1 Posts | Last post June 23, 2013
    • I love your concept and am a late starter in MVVM but love what I am learning and was hoping to get a big start with MVVM In the Box but every title I click tries to save the .MHT file and from what I get from forums, IE 9 and maybe IE8 no longer support MHT files.  Any thoughts?  Thank you for your efforts, I am reading a lot of your work whie trying to get up to speed on MVVM (I'm also trying to learn WPF as well :)

    • Hi Karl, do you have any plan to make this project available on VS2012?
  • Visual Studio 2012

    • Do you plan to make it available on the new VS?
  • It doesn't launch after installation!!

    • Hi Karl,
      The installation happened successfully. But when I try to open VS2010 I get the error:
      "Feature Builder Runtime - The environment variable LocalAppData must be manually configured for Win XP...."
      and yes, mine is a Win XP machine. So how do I configure it?
    • Oh I got it!! you have it in your instructions :)
  • Visual Studio 11 Beta

    • Hey Karl,
      thanks for the hard work you spend on this extension.
      I'm just wondering if you plan to upgrade your extension to support Visual Studio 11 (Beta)?
      Looking forward to your reply!
      Cheers, Kai

      I fails because of an System.IO.PathTooLongException. Any idea to circumvent this problem?
    • I'm planning new version with additional features.  When I ship this, I'll rework the project to shorten up the file names.  
      Sorry you are having this problem.
    • Sorry for the late comment, but... Karl, did you try using the Long Path from the .NET Base Class Libraries? (
    • Cheval,
      It's not my code that has the problem,its Visual Studio.
      To solve this, I'll need to shorten file name and remove some folders.
      Thank you for the tip,
    • Any news on a version that does not throw System.IO.PathTooLongException
    • Any news on the System.IO.PathTooLongException issue?
