The 1201.8 build is extremely slow. Although I don't get crashes as compared to the Feb 17 build. The Feb 17 is much much faster.
I really hope you don't actually plan on that being a beta candidate.
Clicking view designer in an ASP.NET project inside a solution with 10 or more projects creates a delay of 2 minutes before I can type anything.
Build times have increased by 300% since the Feb 17 build.
This FYI and doesn't need a response.
