Developing with DFS in an IDE

My friend and colleague Paul Warren recently posted content that talks about the creation of Enterprise Content Services (like those in DFS) in the context of an integrated development environment (IDE):

WTP support is something the Composer team is hard at work on, and this will change the nature of DFS tooling, too.

Essentially we’re working together to promote more standard developer workflow and development lifecycle by embracing tools developers already use to build services. While WTP assumes Eclipse and Composer is indeed powered by Eclipse, that doesn’t mean that Eclipse is the only IDE for Enterprise Content Service development. We’re working on changing the nature of the DFS SDK, too, to better emphasize, for example, how to use Visual Studio and Windows Communication Foundation directly to build service consumers.

What tools, including IDEs, do you use to build Enterprise Content Services and ECS-based solutions?
