According to New Features in C# 6, you should be able to declare strings as such:
var name = "world";
WriteLine("hello, \{name}");
For the output:
hello, world
I have created a new Console application, set the Target Framework to .NET Framework 4.6, and I am getting the error "Unrecognized Escape Sequence"
I am using Visual Studio Ultimate 2015 CTP Version 14.0.22512.0 DP
