Hello! Is there any way to install this perfect extension in Visual Studio 2012. If not, it would be a problem, if I will install a second Visual Studio Version (VS 2010) on my computer?

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.

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?

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.

      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.

    • This looks like an excellent tool for my team to learn the MVVM pattern.  Can you give me a fair estimate of how much time it would take to work through?
    • James,
      Each person learns at their own pace.  Reading the material is a few hours.  But learning the concepts and then applying those concepts to your scenario is what takes longer.  This training will help.
      Sorry it took longer to reply, I've been sick the last 10 days.
  • Issue with default browser
    3 Posts | Last post February 23, 2011
    • This is great! Congrats, i'am eager for the In The Box Prism...
      I have an issue when click a hyperlink, my default browser is Chrome (in windows and in VS), but the page opens in internet explorer. What can i do to open it in my default browser?
    • Thank you for reporting this.
      What you are seeing is at least functionally correct.
      The content in In the Box is being displayed in the Internet Explorer Browswer control.  So, when a hyperlink is clicked inside the content, its navigating to another page.
      One advantage of using this technique is that I can specify the TARGET property on the anchor tag.  This prevents multiple browser windows from opening up after repeated clicks of internal hyperlinks.
      I hope this explains at least why this is happening.
      Thank you for the feedback and have a super day,
    • Hi Karl
      Thank you for the clarification, I think it would be worthwhile to correct the following line in the "In the box" node chapter:
      "When a hyperlink to the Internet is clicked, the default browser will open and navigate to the target Url."

    • New to VS & .NET, but experienced with Java.  Installed VS2010 Pro on XP vm at work; did the install tweaks for XP as instructed, did the install with no problems.
      Started the video as a step-by-step intro, but when the project loads in VS, it gives 2 errors, both related to the file MainWindow.xaml as shown below.  Hope you can help, and thanks for your time.

  • Guidance Workflow Explorer Window Font & Background color

    • Hello Karl,
      Is there a way to change the font/background color of the Guidance Workflow Explorer window? 
    • Manuel,
      Not that I know of.  The content is actually HTML being rendered.
      I'll look into this for future releases.

    • Hey Karl,
      The in-the-box tool is awesome.  Is there a way for me to develop my own lessons?  I was thinking it would be a great tool for my company as a ramp-up as we bring on new devs.  Is there any documentation on how to develop or plans to release?
      John Oriente
    • John,
      Thank you for your kind remarks.
      I used this tool:  
      There are links to docs and videos on this page.  Basically you use Word to author the docs and use Instant Feature Builder or Feature Builder to create the Feature Extension.
      Best to you,

      I think the screenshot regarding the IntelliSense popup illustration is incorrect because it seems that the related explanations below do not match to the screenshot. Please correct me if i am wrong.

      This page of the training illustrate a thought process.

  • Internatiional Date Formats
    2 Posts | Last post December 01, 2010
    • Hi,
      In Germany dates have the format d/m/Y. This leads to a couple of errors in the application, because when you use the datepicker and choose a date like 13.1.2010 then the application will highlight it as an invalid date. Since i am pretty new to WPF i don't even know where to fix this so that the validation understands the current cultures date format.
    • Sergio,
      Just updated In the Box.  Your localization issues should be corrected. 
      Please let me know if you have any additional issues.
      Thanks again for posting this problem.
  • Any chance we could get the written part as a *.CHM instead?
    6 Posts | Last post November 14, 2010
    • Hi Karl,
      This is just my personal reaction...  I find the space to view the training documentation somewhat limited on my laptop when it is displayed in panes inside VS.  
      I think I'd rather have it delivered in a conventional CHM file like we get with Prism.  Then I could flip back and forth between a maxmized CHM reader and a maximized VS2010.
    • Vic,
      Good feedback.  Agree the desktop experience is better with respect to screen space.  However, you can make the reading window the same side as the code window and swithc back and forth and not loose the navigator functionality.
      FYI:  I have provided a .mht file for reading outside of VS.  Goto my blog and check the downloads at the bottom.
    • Hi Karl,
      After getting more accustomed to using the different panes of the "in-the-box" system tonight, I'm retracting my complaint about the space :).  If I dock the "Guidance Browser" where I dock the source code files in the center of VS then it seems to be big enough, even on my laptop.
      I think the "in-the-box" integration with VS is really genuinely interesting and innovative.  Thanks for all the work on this.
      I've just started to go through the material, but the content looks good.  I'll give more feedback as I get more into it.
    • Karl,
      Ok, given your pointer, I found the download link for the written content as "one-big-MHT-file" (at the end of your 2010-Nov-07 blog post next to the "Skydrive" label).  I think it's good to provide the content in both formats.  It's nice to be able to quickly scroll around the standalone version in a full-size IE window (or maybe on an iPad/WP7 device).
    • Another suggestion.  Since you already have the written content in HTML/MHT form, I think it would be good to expose that as HTML on the web somewhere.  That way search engines will index it and people will start finding it in MVVM-related searches.  You don't want that written content only hidden "in the box".  But maybe you already are planning to expose it like that.
    • Vic,
      I thought about this.  One problem could be the length of the content.  I would have to create a way to navigate the content.  I just don't have the time to produce this format property.
  • Any chance of a Silverlight version?
    2 Posts | Last post November 14, 2010
    • I realize the concepts are basically the same, but I was curious if you are planning a Silverlight version of the solution.  I'm primarily interested in Silverlight.  Having all the materials in SL form is more attractive to me personally than having to try to do the conversion(s) myself.  Just curious.
    • Vic,
      This almost killed me.  I did 90% of this at nights and weekends, one Sunday I did 23 hours straight.
      That said, MVVM is implemented in WPF and Silvelight the same if you use the Blend behaviors.
      Feedback taken, for my next In the Box, I'll be doing Prism.  I'll be sure to have both WPF
