How can you create a Visual Studio extension that references a class library project?

Question

I'm having an issue creating a Visual Studio Extension that calls into another project. I've put a trivial example up on github: https://github.com/craigguest/HelloWorldVSIX

In this example I simply have a "Invoke HelloWorld Command" item in the tools menu that gets it's message from a static property in another project (Message.Text). However, I get this error when clicking the item:

I have added the project as an asset in the manifest, and added the ProvideBindingPath attribute to my package class but I still get the error.

Anything you can do to help would be appreciated, not much is turning up in searches.

You need to sign your class library project with package project key.snk.

right click project named HelloWorld -> Properties -> signing -> enable sign the assembly -> click the dropdownlist below -> Browser... -> select key.snk file in the project named HelloWorld2Parter -> Open -> rebuild your project.
