Getting current user from .Net in Uno/UWP project

[gem4511]

In my UWP project under the Uno platform, I am trying to get current user data from .Net.

In App.xaml.cs, OnLaunched, I execute:
Csla.ApplicationContext.AuthenticationType = "Windows";
var principal = Csla.ApplicationContext.User;

When I examine principal.Identity, Name and AuthenticationType are both "". What am I overlooking? On the premise that it is something very fundamental, I'm embarrassed to have to ask.

It is up to the host (WinForms, WPF, Uno, etc.) to set the current user. In WinForms/WPF CSLA defaults to getting the user from System.Threading.Thread.CurrentThread.CurrentPrincipal (or something along that line).

Or at least it used to do this. A few years ago, Microsoft changed how things work, so the current thread is no longer a reliable source for the user identity. Grumble.

So, assuming CSLA 5 here, the default behavior for CSLA is still to try to get the principal from the thread.

csla/Source/Csla.Shared/Core/ApplicationContextManager.cs

Line 45 in dfaf152

public virtual IPrincipal GetUser()

However, if your app references the Csla.Xaml package, the code attempts to keep the thread set correctly, but ultimately relies on a value maintained in a static field.

csla/Source/Csla.Xaml.Shared/ApplicationContextManager.cs

Line 24 in dfaf152

public override IPrincipal GetUser()

You should see what context manager is being used in your app. You can do this by examining the ContextManager property of the ApplicationContext. If it is one of the types from Csla.Core then you need to set the property (once, on app startup) to the context manager from Csla.Xaml.

Or, if you aren't using the Csla.Xaml package, then copy that class from Csla.Xaml.Shared into your project and have ApplicationContext use it.
