Hello there,
I just unpacked my new laptop on Windows 8, and installed the latest version of Visual Studio Ultimate 2013. Through the server explorer view I tried to add a new connexion to a sql-server database. (Connect to database button)
Each attempts to log-in finished by a crash of visual studio.
Then I tried to get more information about the issue using VS as a debugger for itself. It seems that msvcr110_clr0400.dll thrown an exception. 
Just in case here is the disassembly : 
I tried and re-tried several times, checked for updates, installed an other version of vs (Ultimate2012).Any clue how to fix this ?
Regards,
