Error when creating app package

Question

hello

when I try to create app packagefor the store i get the following error:

Manifest validation error: Line 34, Column 55, Reason: The file name "MainPage.xaml" declared for element "m:Applications/m:Application/m:Extensions/m:Extension" doesn't exist in the package.

I cannot find what that means line 34 is the last line of the Package.appxmanifest am I missing something.

Answer 1

my extensions look like this

<Extensions>
        <Extension Category="windows.backgroundTasks" StartPage="MainPage.xaml">
          <BackgroundTasks>
            <Task Type="audio" />
          </BackgroundTasks>
        </Extension>
      </Extensions>

Answer 2

Remove the StaetPage argument from your extension. That is used for HTML pages only, not for Xaml. We've requested the documentation and manifest editor clarify this.

Answer 3

Thank you then I need to use Entry Point instead what will i have to set that as?

Answer 4

because it then gives the following error when i just remove it.

Error 1 App manifest must define either start page or entry point for application contract 'windows.backgroundTasks'. 

 

Answer 5

Ahh just needed to set it to the class of the page.. My mistake. :-)
