Visual Studio Ultimate 2015 Preview
Download and installation pretty standard, havent noticed anything exceptionally different, lambda debugging looks like it will be pretty cool. Will spend a bit more time playing with the features after I have played with C#6.
List of features
Roslyn (The new C# compiler platform)
Pretty easy to install in to a project just put open a console and type:
Install-Package Microsoft.CodeAnalysis -Pre
Roslyn Website
R#
New platform installer for 9.1 picked up vs2015 and installed, works fine. Looks like some of the c# 6 support is already added as it suggests adding the ?. (Null Propagation) operator.
Resharper Platform Installer
C# 6
Tried out some of the new features including Null propagation, using Static Members ,auto Property Initializers,Getter only auto properties,Exception Filters. Lots of fun :) hopefully will have time to look at a few of these more in depth.

Looks like there is lots of fun ahead for .net!
