Subject RE: Nearing Completion of TypeMapping/Serialization Re-Arch
Date Sat, 26 Jan 2002 00:24:26 GMT

Rich, great job!

I took a scan over the code and it looks like a nice refactoring to me.  I've got some concerns,
mainly centered around performance, but I'm definitely pro checking this in and tackling the
next steps off of this base - do all the tests work with the new code in your sandbox?
