Its C# 6.0. Yes new version of C# which is coming with Visual Studio 2015 has few amazing features. Many of those new features are given below.

Null-Conditional Operator

C# 6.0 includes a new null-conditional operator that helps you write code which handles NullReferenceException more efficiently.

int length = text?.Length;

Also it includes below features.

• Return null if the operand is null
• Short-circuit additional invocations in the call chain if the operand is null
• Return a nullable type (System.Nullable) if the target member returns a value type
• Support delegate invocation in a thread safe manner

Auto-Property Initializers

    public class FingerPrint
	{
		public DateTime TimeStamp { get; } = DateTime.UtcNow;
		public string User { get; } =
		System.Security.Principal.WindowsPrincipal.Current.Identity.Name;
		public string Process { get; } =
		System.Diagnostics.Process.GetCurrentProcess().ProcessName;
	}

Nameof Expressions

	void ThrowArgumentNullExceptionUsingNameOf(string param1)
	{
		throw new ArgumentNullException(nameof(param1));
	}

Primary Constructors

If you specify additional constructors, the constructor call chain must invoke the primary constructor last. This means a primary constructor can’t have a this initializer. All other constructors must have them, assuming the primary constructor isn’t also the default constructor:

	public class Patent(string title, string yearOfPublication)
	{
		  public Patent(string title, string yearOfPublication,
                        IEnumerable<string> inventors)
			...this(title, yearOfPublication)
			  {
				Inventors.AddRange(inventors);
			  }
	}
