What is AgHost.BackgroundTask as a background task in Windows Phone Silverlight 8.1?

Question

When I create a new Windows Phone SIlverlight 8.1 application, there is a background task in the manifest:

 <Extension Category="windows.backgroundTasks" EntryPoint="AgHost.BackgroundTask">
      <BackgroundTasks>
         <Task Type="systemEvent" />
     </BackgroundTasks>
</Extension>

What is it? Is it safe to remove? The only link I could find is not very useful http://msdn.microsoft.com/en-us/library/windowsphone/develop/dn642084.aspx

Answer 1

AgHost.exe is a foreground process. This entry point should allow you to host the background process, if necessary.
