How to declare a C# Record Type?

Question

I read on a blog that C# 7 will feature record types

class studentInfo(string StudentFName, string StudentMName, string StudentLName);

However

Answer 1

There is a way if you're looking for record-like, lazy way of implementing constructors using currently available C# 7 functionality:

class Lazystructor
{
    int a;
    float b;
    WebClient c;

    public Lazystructor(int a, float b, WebClient c)
        =>  (this.a, this.b, this.c) = (a, b, c);
}

A bit of consideration if you're using this on a performance-sensitive scenario, as it's a process of ValueTuple creation and extraction.
