Connected Web Part Series - Part 1

Problem: There is a lot of information relating to web parts however this series is aimed at connected web parts in SharePoint 2010.  This 1st post deals with creating a custom connection between 2 visual web parts (a provider & a consumer).

Overview:  Create a Interface to enable communication between the provider and the consumer web part.  Create Visual User controls to connect to each other. 
Tip: Web Parts are easier to connect than Visual Web Parts, so only use Visual web parts if there is a heavy visual requirement.

 Create an Interface (contract between the provider and consumer web parts)
 Implement the Interface in the Provider web part
Create the Consumer web part as shown below
