MonoTouch: using embedded resx files on iPhone build

I'm able to load and access resx files in Simulator builds of my iPhone app built using MonoTouch. The resx file entry in the csproj file looks like:

  <ItemGroup>
    <EmbeddedResource Include="MapMenu\Resources\MapMenu.resx">
      <Generator>ResXFileCodeGenerator</Generator>
      <LastGenOutput>MapMenu.Designer.cs</LastGenOutput>
    </EmbeddedResource>
  </ItemGroup>

The .resx file itself has an entry like this:

  <data name="Main_Menu" type="System.Resources.ResXFileRef, System.Windows.Forms">
    <value>Main Menu.mm;System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089;Windows-1252</value>
  </data>

and the generated MapMenu.Designer.cs file has开发者_开发问答 this:

    internal static string Main_Menu {
        get {
            return ResourceManager.GetString("Main_Menu", resourceCulture);
        }
    }

As mentioned above, calling the Main_Menu accessor works fine on the simulator. On the device, however, it produces:

<Notice>: Unhandled Exception: System.MissingMethodException: No constructor found for System.Resources.RuntimeResourceSet::.ctor(System.IO.UnmanagedMemoryStream)

<Notice>:   at MapMenu.Resources.MapMenu.get_Main_Menu () [0x00000] in <filename unknown>:0 

Did a few sanity checks, and am wondering at this point if this really is missing functionality in Monotouch.

Thanks,

It looks like a bug in the linker that removes a constructor that is only called through reflection by the resource loader code. As a workaround, you can disable the linker (either using -nolink if you use mtouch directly, or by specifying the linker options in MonoDevelop.

Please file a bug.
