主构造函数未在 C# 6.0 中编译

Primary Constructor is not being compiled in C# 6.0

我正在尝试在 C# 6.0 中编写主构造函数新功能的简单示例,但我无法编译它。 我已将语言版本更改为 c# 6.0,但仍然无法正常工作。

public class Person (string fName, string lName)
{
    public string FName { get; private set; } = fName;
    public string LName { get; private set; } = lName;
}

如何让它编译?

I am trying to write a simple example of the Primary Constructor new feature in C# 6.0 but I am not able to compile it. I have changed the Language version to c# 6.0 but it still doesn't work.

该功能已被删除。
