Roslyn is only usable from VS 2015.
Roslyn being developed in the open at github.com by Microsoft.
It is multi-threaded.
Roslyn makes implementing new language features much easier.
Jimmy showed how C# 6.0 is used in his project AutoMapper.
Here are my unedited random notes on new features in C# 6.0:
0. private setter:
public Type SourceType {get; } //implies setting only in constructor
1. auto-initialize
public string FirstName { get; set; } = "Joe";
public string CreationDate {get;set;} = DateTime.Now;
field or property? if using variable outside a class use property
2. Expression Body Function Members:
public string FullName { get { return FirstName + " " + LastName; }
replaced with
public string FullName => FirstName + " " + LastName;
Can be used for methods as well:
public string GetFullName() => FirstName + " " + LastName;
3. Using Static - pulls in all possible methods from class to be used in class
using static System.Console;
WriteLine("....");
using static system.math;
Round()
using System.Linq.Enumerable
4. Null Propagating Operator (The Elvis Operator) ?.
var x = source?.GetType() ?? sourceType;
5. String Interpolation - use instead of string.Format()
return $"Trying to map {SourceType.Name} to {DestinationType.Name}";
6. nameof()
throw new ArgumentNulException(nameof(context));
7. Index Initializer
static Customer() {
Dictionary
[0] = new Customer(),
[10] = new Customer()
}
}
8. Exception Filter
catch(Exception ex) when System.Threading.Thread.CurrentPrincipal.Indent.Name != "asdf"
9. await/catch/finally
