What is the equivalent of Assembly.GetEntryAssembly() in .NET Core?

In .net framework we could get the starting assembly using:

Assembly.GetEntryAssembly();

But that is removed from .NET Core. Also there is no AppDomain. How can I get access to the entry assembly in .NET Core and Windows Universal applications?

(I need to find all of its embedded resource keys)

One important difference between .NET Framework and .NET Core (including .NET 5-8 etc.) is that when using .NET Core, in a console or Windows application which you launch by starting the ".exe" file, the GetEntryAssembly and all other methods return the ".dll" file, and not the ".exe" file as it used to be the case in .NET Framework. This can introduce a silent bug if you use something like Assembly.Location, etc. when upgrading from .NET Framework to .NET Core.

Assembly.GetEntryAssembly() is available in .NET Standard 1.5, but not in versions 1.0 through 1.4. If you are only developing .NET Core and Universal Windows applications, version 1.5 should be sufficient for your needs.

If I remember correctly, AppDomain is destined to appear in .NET Standard 2.0. It is not available now.

I ended up injecting the entry assembly into the library.

In the library:

class AssemblyHelper 
{
     // This can be called instead of Assembly.GetEntryAssembly()
     public static Func<Assembly> GetEntryAssembly;
}

In the start-up application (which uses the library):

class Program
{
    public static void Main()
    {
        AssemblyHelper.GetEntryAssembly = () => typeof(Program).GetAssembly();

        ....
    }
}
