[Mono-list] Link against a DLL? (System.TypeLoadException)

[Doug]

I'm having some trouble compiling a DLL and linking against it.

Should be trivial, so I must be doing something wrong; I keep getting the
error:
** (./a.out:27535): WARNING **: The class HelloLib.Hello could not be
loaded, used in a, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

Unhandled Exception: System.TypeLoadException: Could not load type
'HelloLib.Hello' from assembly 'a, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null'.

I've written a very basic test case as shown below to illustrate my issue:

hello.cs:
using System;

namespace HelloLib {
  public class Hello {
    public void World() {
      Console.WriteLine("Hello World");
    }
  }
}

assembly.cs:
sing System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

[assembly: AssemblyTitle("HelloLib")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("HelloLib")]
[assembly: AssemblyCopyright("")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

[assembly: AssemblyVersion("1.0.0")]
[assembly: AssemblyFileVersion("1.0.0")]

Compiles ok via:
gmcs /debug- /target:library ./AssemblyInfo.cs ./hello.cs /out:a.dll

--

main.cs:
using System;
using HelloLib;

public class App {
  static public void Main() {
    var h = new HelloLib.Hello();
    h.World();
  }
}

Compiles ok via:
gmcs /debug+ /warn:4 /reference:./a.dll ./main.cs /out:a.out

...

But when I run it I get:
** (./a.out:27535): WARNING **: The class HelloLib.Hello could not be
loaded, used in a, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

Unhandled Exception: System.TypeLoadException: Could not load type
'HelloLib.Hello' from assembly 'a, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null'.

What am I doing wrong?

Obviously this works fine:
gmcs /debug+ /warn:4 ./hello.cs ./main.cs /out:a.out
