How to get app version from manifest to view

Jean-Baptiste Delvaux 1

Greetings,

I would like to simply show the current version of my application on the login page. I didn't create it myself, so I'm mostly self taught in xamarin forms.
Basically, the manifest in the picking.android project and the view I need it to show from is in the picking project. I never truly questioned how the two worked together as they did without issue so far. But for the 1st time, I need to worry about sending information from the manifest to the part of the app I use, and while I could just hard write it, it doesn't really sound professional of me.

Hi, JeanBaptisteDelvaux-5990. Xamarin.Essentials provides the AppInfo class and VersionTracking class which could help you get the version in the shared project directly.

private void Button_Clicked(object sender, EventArgs e) { //1. var currentVersion = VersionTracking.CurrentVersion; //2. var currentVersion = AppInfo.VersionString; }

For more details, please refer to the documentation:

I think Xamarin Essentials has a class for you. It should be appinfo
