Illegal property declarations

I've been trying to figure out which of these is illegal:

public int MyProperty { get; set;}

public int MyProperty { get; protected set; }

public int MyProperty { get; }

public int MyProperty { get{ return 0; } }

public int MyProperty { get { return 0; } set { ; } }

None of them returns an error for me but one of them is supposed to be illegal. Can someone tell me which one and why?

public int MyProperty { get; }

is illegal.

you could simply write 

public int MyProperty { get; private set; }

to archive that

In C# 6.0 all are legal, in prior versions

   public int MyProperty { get; }

is illegal - you can't assign (i.e. set) the returned value. In C# 6.0, however, you can either put

  public int MyProperty { get; } = 0;

or assign value in a constructor

  public MyClass() {
    MyProperty = 0;
  }
