See their site for more details.

The common problem with re-throwing exceptions is that you often lose stack trace information that can be extraordinarily useful for debugging purposes. I'll explain a technique that can be used to force the entire stack to be propagated when an exception is re-thrown.

In attempting to build source from an XML schema using the XSD command line tool, I kept getting an error about an element missing.

I created an HTML Helper for rendering a dropdownlist aka select element from the name/value pairs in an enum and thought I would share.
