Description

Hello, One a Windows App with Appcelerator which calls an asynchronous function on a .NET Core SDK which downloads extensive amounts of data and saves it directly on the App's AppData however, as per limitations from Windows 10, the App must be in the foreground for the whole execution. This creates a problem because if the App gets minimized or it is unfocused while on FullScreenMode, this call will fail. There exists a few restricted capabilities in UWP that may help with this and I wanted to reach out whether these are supported on Ti SDK 7.3 for Windows 10 or whether there's a way to do this within the Titanium SDK. The customer have tried adding ... On the tiapp.xml file however, in the vsbuild folder's manifest these were removed. They also tried prefixing the Capability element with rescap but it failed to compile. Please let us know if you need any more information. Thanks

It failed because the appxmanifest XML doesn't have rescap namespace. We have merged the fix in master (https://github.com/appcelerator/titanium_mobile_windows/pull/1281/files). With the fix, rescap Capabilities can be defined like below.

    <windows>
       <manifest>
         <Capabilities>
           <rescap:Capability Name="extendedBackgroundTaskTime"/>
           <rescap:Capability Name="extendedExecutionUnconstrained"/>
         </Capabilities>
       </manifest>
     </windows>

*Closing ticket.* Verified improvement in SDK Version 7.5.0.v20180911212648. rescap capabilities can now be defined without the application throwing an error. *Test Steps (FR Passed):*

Created a new titanium application

Added the following in to the `Tiapp.xml`

    <windows>
       <manifest>
         <Capabilities>
           <rescap:Capability Name="extendedBackgroundTaskTime"/>
           <rescap:Capability Name="extendedExecutionUnconstrained"/>
         </Capabilities>
       </manifest>
     </windows>

Ran the app using `appc run -p windows --build-only`

Application was able to build without an errors

*Test Environment*

   Name  = Microsoft Windows 10 Entreprise
   Version  = 10.0.15063
   Architecture = 64bit
   CPU Cores = 8
   Memory = 15.9GB
