Change the app manifest parameters programmatically

Question

I use FullTrustProcessLauncher to launch another app from my UWP application and I want to set the parameters of my manifest:

<desktop:ParameterGroup GroupId="OtherGroup" Parameters=aVariable/>

Is there a way to change the app manifest programmatically of an UWP app?

Answer 1

Unfortunately, there is no such way :

The package manifest is an XML document that contains the info the system needs to deploy, display, or update a Windows app. This info includes package identity, package dependencies, required capabilities, visual elements, and extensibility points.

That means that manifest is used to deploy app and set its permissions to the system. So it cannot change values in runtime. That's why such ability isn't implemented.
