Best Practices for Wrapping Native Code

At our talk on Framework Design Guidelines at the PDC, Krzysztof and I were asked about resources for wrapping a native code library in a nice managed code framework. 

This is an extremely common pattern.  Organizations frequently have large "heritage" investments in C\C++\COM code and now they need to expose that functionality is way that is productive and familiar to .NET developers.   Wrapping the native functionality in a well-designed managed library maximizes the productivity of the breadth of .NET developers. 

I promised to blog a few resources on how to best accomplish this.
