Are expression-bodied methods automatically inlined?

Are the following equivalent in non-debug compilation?

        public byte[] GetBytes(char value) => GetBytesInternal(value, 2);

        [MethodImpl(MethodImplOptions.AggressiveInlining)]
        public byte[] GetBytes(char value) => GetBytesInternal(value, 2);

Is there any guide to when inlining is done by compiler, so as to avoid these messy attributes?

Why not create a program and see the IL output? – EJoshuaS - Stand with Ukraine Jun 23 '20 at 12:21

@EJoshuaS-ReinstateMonica - Inlining decisions are a JIT compiler decision, not the C# compiler (hence the existence of the attribute). In the IL, the method will not be inlined. – Damien_The_Unbeliever Jun 23 '20 at 12:48
