I am responsible for a team of developers who will are about to start development of a light weight insurance claims system. The system involves a lot of manual tasks and business workflows and we are looking at using Windows Workflow (.NET 4.0).

I'm working with Windows Workflow 4, and I need to create a C# activity that, basically, inherits from the Sequence activity. I want it to look just like the Sequence activity, so a user can drag and drop other activities onto it from the designer.
