Immutable types are a best practice nowadays. However, when a C# class has a lot of properties it means ctor will have lots of parameters. Property initializers are easier to read and understand as well.
Can we have a way of initializing properties on immutable types? I have read about C# 6 auto-property initializers and unless I am mistaken they only help with compile-time constants.

PS: please don't do this by introducing new types (e.g. why have some sort of 'record' when we already have classes and structs?).
