.net - Expression bodied get / set accessors feature in c# 7.0

Question

I'm having this code in a class

private string test;
public string Test
{
    get =>  test;
    set => test = value;
}

But the compiler won't let me compile. It says

CS1043 { or ; expected 
CS1513 } expected

I'm using VS 2017 and targeting .NET FW 4.6 with a MVC 5 Project

Any idea why it isn't working?

Answer 1

You have to set the compiler to version 7 in your project.

Project properties → (tab) Build → Advanced → Language version = C# 7.0

UPDATE BY @gsharp

check also your (NuGet) reference to the .NET Compiler platform Microsoft.Net.Compilers.
