So what will it contain? Well as you might know Microsoft acquired HockeyApp in late 2014. HockeyApp then joined forces with the Application Insights team. They strengthened their vision on crash reporting and gathering analytics for your apps. I have even heard that in the near future you should be able to correlate your analytics from your App with the analytics from your back-end. This will bring new exciting insights into your software. Next to that HockeyApp is also great at beta testing and distributing your Apps, I personally don't expect that Microsoft will change a lot here, but that's only for the better since it already works excellent in HockeyApp.

One quick downside I noticed in the presentation is the fact that it doesn't support Cordova. I saw Xamarin, React Native and Objective-C / Swift. I'm not sure why Microsoft didn't include Cordova in it because they are still busy with the TACO tools in Visual Studio. Maybe it will be added in the future, hopefully.
So Mobile Center looks great and I can't wait to play with the preview. Let me know what you guys think!
