Error 00816: Tool is not valid

I have a custom GP tool that I've written in C# for 10.1.  I've compiled it, registered it, used it to build a model, and it runs it desktop.  Now I want to publish it as a GP service.  I go through that process and it publishes.  But it won't run as a published tool.  I get the 816 error stating that it's not valid.  I've validated it in model builder, I've analyzed it before publishing and those are all fine.  What else do I need to do????  This model worked in 10.0 but not in 10.1.
