I'm trying to share a resource file (.resx file) from my web (RIA Service?Silverlight Host) to client (Silverlight) by linking the resource file into my client. When I try to access resources using the ResourceManager object I get the following error:

System.Resources.MissingManifestResourceException was caught
  Message=Could not find any resources appropriate for the specified culture or the neutral culture.  Make sure "PPCa.Modules.ProjectManager.Client.ViewModels.ResourceStrings.resources" was correctly embedded or linked into assembly "PPCa.Modules.ProjectManager.Client" at compile time, or that all the satellite assemblies required are loadable and fully signed.

  InnerException: 

Edit:

When I say I was linking the resource file, I mean I am using the 'Add as Link' option when adding the existing resx file to my project.
