What can I do in C# 5 with .Net 4.5 that I couldn't do in C# 4 with .Net 4?
.net, .net-4.5, asp.net-4.5, c#, c#-5.0
Solution
See What's New in the .NET Framework 4.5 and What's New for Visual C# in Visual Studio 2012.
The biggest new feature of C# 5.0 is better support for asynchronous operations, using the new `await` keyword.
Problem
I have Visual Studio 2012 RC installed on Windows 8 Release Preview and my question is are there any useful new features not related to Metro, or is Metro what seperates .Net 4 and .Net 4.5?
