Description
In custom collections generated code, the code generated for the following snippet contains byte* as a generic argument, causing a compiler error.
Input Code:
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.Marshalling;
[assembly:DisableRuntimeMarshalling]

[MarshalUsing(CountElementName = "pRefSize")] ref System.Byte[] pRef,
[MarshalUsing(CountElementName = "pOutSize")] out System.Byte[] pOut,
out int pOutSize);
