C# - UWP AppInfo throws NotImplementedException

I'm developing a C# WinForms app, using the UWP API. I'm attempting to read notifications programatically, and I have succeeded so far. However, whenever I call AppInfo from the UserNotification class, I get a NotImplementedException, no matter what property I read from AppInfo.

Does anyone have any suggestions?

I have only been able to find 1 answer to this question and it's not very useful, and also a few years old. This is a major roadblock in my project, any help is massively appreciated!

Thank you in advance.

    Hello, Welcome to Micorosoft Q&A,

    UWP AppInfo throws NotImplementedException

    Derive the exception, it looks notification.AppInfo.DisplayInfo has not implemented for WinForm platform. For this scenario, we have a workaround for getting AppInfo with AppDiagnosticInfo api. Please refer the following code 

    var list = await AppDiagnosticInfo.RequestInfoAsync();  
var currentPackage = list.Where(o => o.AppInfo.PackageFamilyName == Package.Current.Id.FamilyName).FirstOrDefault();  
if (currentPackage != null)  
{  
    AppInfo currentAppInfo = currentPackage.AppInfo;  
    var display = currentAppInfo.DisplayInfo;  
}

    Update

    UserNotificationListener has no DualApiPartitionAttribute, it means it is not support for desktop app, I'm afraid you could not use desktop app to get all other app's notifications.
