We are seeing a lot of great Entity Framework questions (and answers) from the community on Stack Overflow. As a result, our team is going to spend more time reading and answering questions posted on Stack Overflow.
We would encourage you to post questions on Stack Overflow using the entity-framework tag. We will also continue to monitor the Entity Framework forum.
