I'm attaching a presentation and code for developing an assembly connector for SharePoint 2010 BCS. I plan to do a series of blogs about different elements of the solution, but wanted to get this posted for those that attended my talk. It illustrates a connector that supports streaming, configuration, and secure store. Unfortunately the code won't actually work without setting up some additional sharepoint sites and a web service. I've included the code for the web service, but the SharePoint site i just setup manually. The following are included in the attached zip:
Code Camp - BCS.ppt - The presentation
AssemblyConnectorDemo.completed.zip - the connector implementation
Customer Service and Sales Site.zip - a wsp containing the SharePoint site that is being accessed through the connector, and a zip of the solution implementing the service being accessed by the connector in the demo.
