Check out this suggestion posted over on MSDN Product Feedback (LadyBug).
What I don’t understand is why people think they are entitled to the most current bits. It amazes me that people actually believe they should be plugged into the build process at Microsoft. People actually have the nerve to demand current bits because they can’t get VSTS to perform stable enough for them to use it. Come on people, it’s a beta… deal with it. You have zero recourse if it doesn’t work. Just because you report a show-stopper bug doesn’t mean you are entitled to the updated bits fresh from the devs change-set. Everyone please, go login to LadyBug and mod this stupid suggestion down.
If you haven’t noticed I tend to have issues with beta testers. Actually, I have issues with the “not-so-intelligent” people that tend to live within every public beta. It reminds me of a book I remember reading my kids… “If you give a mouse a cookie, he's going to ask for a glass of milk.”
