DynamicProxy apparently doesn't support
System.UIntPtrproperly. This may become more of an issue now that C# 9 has a dedicated keyword for this type (nuint).This short program:
will fail with:
I narrowed this down to just
UIntPtr, which isn't covered here:Core/src/Castle.Core/DynamicProxy/Generators/Emitters/SimpleAST/DefaultValueExpression.cs
