Have to use the Type overload as they can't be used as a generic parameter; however fails due to MakeGenericType I assume for same reason?

Unhandled Exception: System.TypeLoadException: The generic type 'SizeComputer`1' was used with an invalid instantiation in assembly 'ObjectLayoutInspector, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
   at System.RuntimeType.MakeGenericType(Type[] instantiation)
   at ObjectLayoutInspector.InspectorHelper.GetSizeOfValueTypeInstance(Type type)
   at ObjectLayoutInspector.InspectorHelper.GetSize(Type type)
   at ObjectLayoutInspector.TypeLayout.<GetLayout>g__DoGetLayout|24_0(<>c__DisplayClass24_0& )
   at ObjectLayoutInspector.TypeLayout.GetLayout(Type type, TypeLayoutCache cache, Boolean includePaddings)

Hey, @benaadams , sorry for the late reply, I completely missed this bug.

It seems that MakeGenericType just "works" on .NET Framework for ref structs, but fails on .NET Core.

I'm not sure what can I do here, unfortunately, besides failing with more appropriate error message.

I'll think about other approaches though...
