How to fix "satellite assemblies required are loadable and fully signed" error?

[Dave Kennedy]

Hi,
Env:
Windows XP,
Visual Studio 2008,
Target Framework: .Net Framework 3.5
C#,
POS for .NET v1.12 SDK

I am developing a custom MSR Service Object (PoshMsr.cs) based on ExampleMsr.cs.

There is an issue with the TargetInvocatio nException exception:

1. Make sure "Strings.resour ces" was correctly embedded or linked into assembly "POSH_MSR_S O" at compile time,
2. or that all the satellite assemblies required are loadable and fully signed.

I don't know if it is 1. or 2.
The exception is thrown after this code in the Service Object (PoshMsr.cs)

    public PoshMsr()
    {
      // Initialize ResourceManager for loading localizable strings
      rm = new ResourceManager("Strings", Assembly.GetExecutingAssembly() );

      // Initialize device properties
      Properties.CapIso = true;
      Properties.CapTransmitSentinels = true;
      Properties.DeviceDescription = rm.GetString("IDS_MSR_DEVICE_DESCRIPTION");
    }

The default SO Microsoft.Point OfService.Examp leServiceObject s.dll is signed
but POSH_MSR_SO.dll is not signed.

Does the dll need to be signed and How can I sign the dll ?

Thanks
