Client-side MVC Architecture

April 17, 2013 Leave a comment

I am excited to be presenting tomorrow night at the WNC .NET Developers Guild.

Here is a summary of what we will be presenting:

With social sites becoming so popular like Facebook, Twitter, LinkedIn, etc, we are reaching a point where consumers are demanding applications and systems that can deliver real-time experiences.  We will look at the landscape and discuss some of the most popular frameworks currently available.  We will also look at the question of ubiquity and how we can leverage good architecture and design to support such models.  Finally, we will take a look a one such architectural approach and look at the pros and cons with such an architecture.

Hope to see all of you there!

Update:  Here is a link to my slide presentation.

Developing Windows 8 – Unable to activate Windows Store app

April 16, 2013 Leave a comment

I have encountered the following error several times and I am sure that I will continue to encounter it in the future.

Unable to activate Windows Store app.  The activate request failed with error ‘This app failed to launch because of an issue with its license.  Please try again in a moment.’

Unable to activate Windows Store app

If you come across this error when you fire up Visual Studio, you may end up doing a lot of things to try to resolve the problem.  Several that come to mind are:

  • Re-starting Windows
  • Re-starting Visual Studio
  • Modifying your package manifest

None of these actually fix them problem.  It turns out that the majority of time that you encounter this problem is because you have already installed the solution into start screen.  I would recommend that anytime you encounter this error, that you always first uninstall the application from the start screen and then try to run it from Visual Studio again.

Hope this helps…
