When I add my provider and consumer web parts to a web part page (following Walkthrough: Creating Connectable Web Parts in SharePoint Foundation) I find that the 'Connections' option on my webpart is disabled. I hover over the option to see the tooltip

The Web Part you are connecting from does not allow authoring of connections.

What causes this message to appear, and how can I fix it?

This error simply means that the web part being edited does not support connections - it has not been coded correctly.

In this case I was receiving the error because I placed the ConnectionProvider and ConnectionConsumer attributes and methods on the UserControl objects inside the Web Parts, rather than the Web Parts themselves.
