"To property with backing field" and Visual Studio 2015

I'm using the ReSharper 2018.3.1 on "Visual Studio 2017" and "Visual Studio 2015". The problem is that on VS2017 when I convert an Auto Property with a backing filed I obtain:

public bool PropBool
{
    get => _propBool;
    set => _propBool = value;
}

The problem is that on VS2015 this code is not valid (for C# 7.0).

Exist a way to configure 'ReSharper' to works always with a statement body?
