Description Widagdo Setiawan 2016-03-14 00:21:31 UTC
- Compiles under Visual Studio 2015 update 1
- But failed on mono 4.3.2.467/ba2e5e4
  error CS0842: Automatically implemented property `Cs0842ExpressionBodyGetterBug.MyGetter' cannot be used inside a type with an explicit StructLayout attribute

-Sample code
    [StructLayout(LayoutKind.Explicit, Size = 8)]
    public struct Cs0842ExpressionBodyGetterBug
    {
        [FieldOffset(0)]
        public int DummyVariable;

        public int MyGetter => 5;
    }

I think MyGetter should not be implemented as Automatically implemented property. Instead, it should be implemented as a normal getter with body "return 5;"

Fixed in master and Mono 4.4
