... you can enable push notification support in a brand new Windows Phone 7.1 project—and send notifications from a new ASP.NET MVC 3 Web Application running in Windows Azure—in less than two minutes!
All of this is made possible by delivering functional, discrete, and composable NuGet packages. I’ve gotten a lot of feedback (positive and constructive, but fortunately mostly positive) about the Windows Azure Toolkit for Windows Phone, and invariably people have said that it’s too hard to decompose the sample applications – often times people just want Push Notification support or user management, and it’s too hard to get rid of the rest. --Wade Wegner
Overall, these great new NuGet packages are something that Windows Phone devs should get their hands on immediately. They make it easy to build advanced application features very quickly and they also make it simple to update your existing apps with major enhancements.
