From Mexico, yes I am on vacation, I wanted to let you know that CTP4 is ready for you trlo download and take it for a spin.
The main new thing is the seperation of the project view in to a file based view (Solution Explorer) and a seperate Schema View which is the virtual representation of you parsed SQL Server schema inside the project.
Besides that we did a lot of bug fixing.
Hope you like it.
