DefaultResourceManager Error

I am gettng an error trying use the DefaultResourceManager.
Here is the initialization (no errors thrown):
'Set the default resource manager before calling initialize component
GoImage.DefaultResourceManager = New ResourceManager("MIEGraphicalWorkflow.Resources1", Me.GetType().Assembly)
Here is the attempt to use an image:
ap.PortImage = GoImage.DefaultResourceManager.GetObject("smallfail")
Throws this error:
"An error occurred creating the form. See Exception.InnerException for details. The error is: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "MIEGraphicalWorkflow.Resources1.resources" was correctly embedded or linked into assembly "MIEGraphicalWorkflow" at compile time, or that all the satellite assemblies required are loadable and fully signed."
Any ideas?

Well… not sure. Make sure the .resx file is set to “Build Action” of “Embedded Resource”.

I will note that any place in the samples where we use GetObject, we cast it to (Bitmap) or (Image).
