Description

This is the same issue that has been fixed before here, but with .net10-rc1 it surfaced again.

Describe the bug

When building the app with PublishAot=true, getting a string array from ApplicationData.Current.LocalSettings and casting it to the string[] type I get:
System.InvalidCastException: 'Unable to cast object of type 'WinRT.IInspectable' to type 'System.String[]'.'

Steps To Reproduce

Set in csproj:
<PublishAot>true</PublishAot>

ApplicationData.Current.LocalSettings.Values["test"] = new string[] { "a", "b", "c" };
var array = (string[])ApplicationData.Current.LocalSettings.Values["test"];
