ive read every relevant stack overflow post on this specific issue and the only one that got me anywhere was running it from within an msix package app but i dont understand why i have to do this to access the api? ive seen other people online access the winrt api straight from a .net console app or even a python app.

TeBeCo•7/11/24, 3:41 AM

i would ask in #gui then if it's specific to the project type because iirc you change change the tfm for stuff about it

pride month gurtOP•7/15/24, 10:46 PM

@TeBeCo sorry to revive the thread but im not trying to use this in a gui. ive managed to get this to work by using a windows packaging project but i still dont understand why its not possible to work in a console app

pride month gurtOP•7/15/24, 10:47 PM

the windows.ui.notifcations.managementwindows.ui.notifcations.management api isnt listed on the list of apis that only work in packaging projects

pride month gurtOP•7/15/24, 10:48 PM

https://learn.microsoft.com/en-us/windows/apps/desktop/modernize/desktop-to-uwp-supported-api

Windows Runtime APIs not supported in desktop apps - Windows apps

This article describes WinRT APIs that aren't supported for use in desktop apps, or that have restrictions.

according to this

Ppride month gurt @TeBeCo sorry to revive the thread but im not trying to use this in a gui. ive ...

TeBeCo•7/16/24, 5:16 AM

because it's part of GUI binary code

TeBeCo•7/16/24, 5:17 AM

so by created a packaging project the dependency tree is pull these binary with it

TeBeCo•7/16/24, 5:17 AM

that's why I suggested to ask in #gui

TeBeCo•7/16/24, 5:17 AM

it is part of a GUI package

TeBeCo•7/16/24, 5:17 AM

even if you're writing a console app you'll need that package

TTeBeCo because it's part of GUI binary code

pride month gurtOP•7/16/24, 7:58 PM

I dont really understand this since windows.ui.notifications.managementwindows.ui.notifications.management is part of the windows 10 sdk.

UserNotificationListener.GetNotificationsAsyncUserNotificationListener.GetNotificationsAsync works outside of a packaging project but UserNotificationListener.GetNotificationUserNotificationListener.GetNotification doesnt

pride month gurtOP•7/16/24, 8:00 PM

also it would help me if you could point me to which gui package specifically you are referring to

ive changed it to .net 8.0 targeting windows 10.0.19041.0 using the windows sdk

pride month gurtOP•7/16/24, 8:16 PM

it can get the list of notifications perfectly fine

pride month gurtOP•7/16/24, 8:16 PM

but cant seem to bind an event handler

TeBeCo•7/17/24, 5:09 PM

i can't that's why i can't be more specific

TeBeCo•7/17/24, 5:09 PM

i'm trying to give you leads on what to try to isolate it because it's the maximum i can actually do

TTeBeCo i can't that's why i can't be more specific

pride month gurtOP•7/17/24, 7:00 PM

nowhere in any documentation does it suggest that i need anything more than the windows 10 sdk

pride month gurtOP•7/17/24, 7:00 PM

my version of windows is above the minimum

pride month gurtOP•7/17/24, 7:02 PM

and shouldnt rely on any ui/gui packages other than windows.ui

pride month gurtOP•7/17/24, 7:03 PM

the windows.ui.notifications.managementwindows.ui.notifications.management api is also not listed under the list of apis which require a package identity
