Custom TypeEditors in external assembly

Question

Hi, I'm having some types implemented in C++/CLI that I want to be editable via a property panel with a custom type editor (derived from UITypeEditor). The problem is, I want to implement the type editor in C#, hance in a different assembly. This of course implies a circular dependency (the C++/CLI has to reference the C# assembly to specify the custom type editor to be used and the C# assembly has to reference the C++/CLI assembly to be able to use the type implemented there). My question now is: is there any way to implement a custom type editor in an external assembly while avoiding a circular dependency (late binding via reflection is no solution for me)?
