Detect app first run

[Gabboxl]

Describe the bug

The Windows App SDK should provide an easy way to detect the app's first run.

This can be useful to display first-run messages, instructions, etc.

Steps to reproduce the bug

In UWP the ApplicationDeployment.CurrentDeployment.isFirstRun property is available to accomplish this, in the WinAppSDK this property isn't available.

An usual way is to read/create a registry key in HKEY_CURRENT_USER\SOFTWARE

The only reference to this ApplicationDeployment I am able to find is the .Net framework's System.Deployment.Application.ApplicationDeployment. Is this what you are referring to? Does this not work?

ApplicationDeployment.CurrentDeployment.isFirstRun

This is an old .NET API, not UWP but doesn't seem to be available on .NET Core. However the .NET (Windows) Community Toolkit has similar functionality. See the SystemInformation.IsFirstRun property.

Yes, I am referring to the .NET Framework as it looks like it is only available for UWP apps.

However the .NET (Windows) Community Toolkit has similar functionality. See the SystemInformation.IsFirstRun property.

Thank you, works great! I wasn't aware of that property. I used version 7.1.2 of CommunityToolkit.Common as the 8.0.0/8.1.0 versions have a bug that causes a crash when calling the API.

So should this issue be considered solved now?

This is trivial to handle yourself in packaged apps eg

var values = ApplicationData.Current.LocalSettings.Values;
if (!values.ContainsKey("1stRun"))
{
...DoFirstRun...
values["1stRun"] = true;
}
