What's new with AeroGear in Windows 10

Windows 10 1st preview has been released for a long time, and the final version will be released soon (July 29). AeroGear developers can pay attention to some of the latest improvements, among which the biggest improvement is that there is no longer a need for 2 different binary packages, and the same code can run on Windows desktop, tablets and phones (even Xbox). This means that if you want to migrate your application, or you have `#if` states, you need to modify them and run the following code to check:

 using Windows.Foundation.Metadata; 
 
 // you used to have  
 # if WINDOWS_PHONE_APP
 // something for hardware buttons  
 #endif 
 
 // now you can use Metadata to make it a runtime check  
 if (ApiInformation.IsTypePresent( "Windows.Phone.UI.Input.HardwareButtons" ))
 {
 HardwareButtons.BackButtonPressed += BackButtonHandler;
 }

To use Mobile specific API you need to add Mobile Extension SDK:
This isn't to say your app can't run on desktop, so you need to run the tests above, or you can choose to continue running it only on mobile.
Visual Studio 2015 cannot handle these automatically yet. Here is a powerful shell script that can automate many things.
Also new on the Windows 10 front is that 'metro' apps no longer launch in full screen by default.
