Could not resolve type with token 01000013 .. (expected class '....StringCodec') on mono 6 mono-service

Thank you for awesome project.

Following code works well on almost every platform except mono 6 (mono-service)

// target framework: 4.7.2
// SharpZipLib-1.4.1
namespace ZipTest
{
    internal class Program
    {
        static void Main(string[] args)
        {
            System.Console.Error.WriteLine($"Hello: {ICSharpCode.SharpZipLib.Zip.StringCodec.Default}");
        }
    }
}

$ cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)

$ mono --version
Mono JIT compiler version 6.12.0.107 (tarball Wed Dec  9 21:42:51 UTC 2020)
...

$ mono zipTest.exe
Hello: ICSharpCode.SharpZipLib.Zip.StringCodec

$ mono-service ZipTest.exe
$ sudo tail /var/log/messages

Jan 13 19:20:56 localhost mono: ZipTest.exe: Could not resolve type with token 01000013 from typeref (expected class 'ICSharpCode.SharpZipLib.Zip.StringCodec' in assembly 'ICSharpCode.SharpZipLib, Version=1.4.1.12, Culture=neutral, PublicKeyToken=1b03e6acf1164f73')

On mono 5 both mono and mono-service works well but on mono 6 only mono works.
To make run with mono-service on mono 6 what should I check?

What the error indicates is that the Assembly that gets loaded isn't the same as the one used for compiling the binary. I have no idea how that happened though, but perhaps reflection can tell you more...

foreach (var c in typeof(ICSharpCode.SharpZipLib.Zip.ZipFile).GetConstructors()) 
{
    Console.Error.WriteLine(" - " + c);
}

$ mono zipTest.exe
 - Void .ctor(System.String, ICSharpCode.SharpZipLib.Zip.StringCodec)
 - Void .ctor(System.IO.FileStream)
 - Void .ctor(System.IO.FileStream, Boolean)
 - Void .ctor(System.IO.Stream)
 - Void .ctor(System.IO.Stream, Boolean, ICSharpCode.SharpZipLib.Zip.StringCodec)

$ mono-service zipTest.exe --debug
 - Void .ctor(System.String)
 - Void .ctor(System.IO.FileStream)
 - Void .ctor(System.IO.Stream)

I'v created discussion on MONO project.
If I get an answer I'll update.
Thank you.
