C# 6.0 is auto-property initializers

The next new feature of the C# 6.0 is auto-property initializers and get-only auto property. The main problem that they suppose to solve is immutable type declaration. Before C# 6.0, if you want to create immutable type with properties, you have no possibility to use auto property:

1	public string Property { get; set; }

So, you were forced to use regular get-only (read-only) property with read-only backing field:

1 2 3 4 5 6 7

private readonly string prop; public string Prop { get { return prop; } }   public Ctor() {     prop = "value"; }

Now, with C# 6.0, you can write:

1	public string Prop { get; } = "value";

Of course, you can use property initialization not only with read-only auto property. Regular one is also working well:

1	public string Prop { get; set; } = "value";

The same as static one:

1	public static string Prop { get; set; } = "value";

You can even use expressions to initialize property:

1 2 3 4 5

public string Prop { get; set; } = InitializeProperty(); public static string InitializeProperty() {     return "value"; }
