Use Windows Hello in C# WPF application

Question

Use Windows Hello in C# WPF application

Jeronymite 0

I have seen W10 apps prompt for authentication using the standard login credentials window, particularly the Windows Hello PIN.

In a Windows 10, C#, WPF, .NET Framework 4.8 application, how can this be invoked to authenticate a user for an action? I'm not using VS or NuGet, so manual steps required, please.

Thanks.

Windows Hello is mainly used in UWP : https://learn.microsoft.com/en-us/windows/uwp/security/microsoft-passport-login

If you use it in a classic WPF app, you get

The process has no package identity. (Exception from HRESULT: 0x80073D54)

(tested on Windows 10 22H2)

So you need to package it (Desktop Bridge or other)

Thanks, and understood. So, how can this be invoked to authenticate a user in the system configuration I've listed? What example code is available?

Thanks.

I posted the link to the MS sample code I tested in WPF (with references to System.Runtime.WindowsRuntime.dll and Windows.winmd as usually to use UWP namespaces), but you must use a Package in WPF)

Thanks. Apologies I did not realise that it would detail a solution. Just assumed it was for UWP from the link. Again, thanks.
