In Part 1 I covered a simple implementation of the Authentication feature and portable class libraries from the Azure Mobile Services SDK.  However, as mentioned in the "Good & Bad So Far" section; there is not a whole lot of code reuse other than the Azure endpoint and secret key.  Let's refactor a bit by adding some interfaces, conditional compile statements and the MVVM Light Event Bus to help the same solution operate cleaner. The "after" code for part one is available here. Building Our Core PortableAzure.Core is our Portable Class Library that is being shared with the Windows 8 and  Windows Phone project in the attempt to reuse as much code as possible.  However,...

Azure Mobile Services is undoubtedly one of the best platforms to emerge from the Azure group over the last year. If you are a mobile developer and not taking advantage of it; I encourage you to do so.  There are many video and blog posts available to get you started at http://www.windowsazure.com/en-us/develop/mobile/ . One of the features you may not be aware of is Azure Mobile Services is a Portable Class Library (PCL) available through nuget. If you are not familiar with PCL's see my "Move Your ViewModels" series. There is a caveat however when using Azure Mobile Services in your PCL; although all of the data calls to the services are...

In the first part I covered how to get the initial project setup and share the ViewModels and ViewModelLocator between a Windows Phone 8 project and a Windows Store Application.  In this post, I'll add a DataService and a Model class that will be used to get the most recent posts from the Windows Phone Blog and display the results. Adding DataService and Async to Portable Class Library The purpose of the DataService in the context of this project is to retrieve the RSS feed from the Windows Phone Blog (http://blogs.windows.com/windows_phone/b/wpdev/rss.aspx) using the async methods available in the 4.5 Framework, return a collection of our Headline class object for...

Portable Class Libraries  Portable Class Libraries were added as a project type in the interest of creating an assembly that you could use across the .NET Framework, Silverlight, Windows Phone 7, or Xbox 360 platforms without modifications.  Well, not really that easy.  There is some work to do and as you get into the development of PCLs you'll find out that there is really a sliver of what you'd hope is supported.

I have been using this MVVM framework exclusively for a...
