Enabling "PublishSingleFile" may causes "ResourceManager.Current" to throw an error

[NXY666]

Describe the bug

When I tried to enable "PublishSingleFile" and attempted to publish it as a single executable file, an error occurred when accessing ResourceManager.Current:

Unable to find the specified file.
   at WinRT.ExceptionHelpers.<ThrowExceptionForHR>g__Throw|39_0(Int32)
   at WinRT.ExceptionHelpers.ThrowExceptionForHR(Int32)
   at ABI.Windows.ApplicationModel.Resources.Core.IResourceManagerStaticsMethods.get_Current(IObjectReference)
   at Windows.ApplicationModel.Resources.Core.ResourceManager.get_Current()
   at Demo.MainWindow..ctor() in E:\Projects\Demo\MainWindow.xaml.cs:line 17

Steps to reproduce the bug

1. Enable the PublishSingleFile option in win-x64.pubxml

2. In the constructor of MainWindow, write the following code:

   public partial class MainWindow
   {
   public MainWindow()
   {
       string filePath = @"D:\demo.txt";
   
       try
       {
           var curr = ResourceManager.Current;
       } catch(Exception e)
       {
           File.WriteAllLines(filePath, [e.Message, e.StackTrace]);
       }
   }
   }

3. Open this window on OnLaunched:

   protected override void OnLaunched(LaunchActivatedEventArgs args)
   {
       MWindow = new MainWindow();
       MWindow.ExtendsContentIntoTitleBar = true;
       MWindow.Activate();
   }

4. Publish, then run the exe and check the output errors in the root directory of the D drive:

   Unable to find the specified file.
   at WinRT.ExceptionHelpers.<ThrowExceptionForHR>g__Throw|39_0(Int32)
   at WinRT.ExceptionHelpers.ThrowExceptionForHR(Int32)
   at ABI.Windows.ApplicationModel.Resources.Core.IResourceManagerStaticsMethods.get_Current(IObjectReference)
   at Windows.ApplicationModel.Resources.Core.ResourceManager.get_Current()
   at Demo.MainWindow..ctor() in E:\Projects\Demo\MainWindow.xaml.cs:line 17

I think the ResourceManager from the Microsoft.Windows.ApplicationModel.Resources namespace will work with single file publishing.

Thank you very much!

After replacing it with the ResourceManager you mentioned, it worked. I spent several months looking for a solution. 😂
