I'm working as an InteractionDesigner with Blend5 inside a huge WPF-Project. The performance of this application is just horrible mainly because of the communication with TFS. Every 2-3 minutes Blend tries to communicate with TFS and blocks the UI. Productive work with Blend 5 is nearly impossible. Are there any tricks to speed up Blend 5 when working inside TFS projects?
(If you want people to build awesome applications for your ecosystem you have to provide them with tools in order to do so. I'm really sorry but the current developer experience is really, really frustrating.)
