[dotnet-sdk-10.0.100-alpha.1.25057.15] GitExtensions crashes due to Assembly.GetCallingAssembly().GetManifestResourceStream() doesn't load resource file

[Junjun-zhao]

Description

When run the 3rd party application with the latest .NET 10 build, it breaks with error: System.TypeInitializationException: The type initializer for 'ICSharpCode.TextEditor.GutterMargin' threw an exception. After investigating, we found the issue is caused by Assembly.GetCallingAssembly().GetManifestResourceStream() method doesn't load the resource file when running against with .NET 10.

Other information

Findings:
When debugging into the app source code, we found the problem should be caused by below line of code (line27 In ICSharpCode.TextEditor.Src.Gui.GutterMargin.cs), it doesn't load the resource file with .NET 10 runtime:
var cursorStream = Assembly.GetCallingAssembly().GetManifestResourceStream("ICSharpCode.TextEditor.Resources.RightArrow.cur")

The app calls Assembly.GetCallingAssembly() in a static constructor. Small repro:

using System.Reflection;

Test.DoSomething();

class Test
{
    static Test()
    {
        Console.WriteLine(Assembly.GetCallingAssembly());
    }

    public static void DoSomething()
    {
        Console.WriteLine("DoSomething()");
    }
}

On .NET 9, this prints the program name. On current dotnet/runtime, this prints System.Private.CoreLib.

This is regression from #108167. cc @davidwrighton @AaronRobinsonMSFT
