MicroORM - A Dynamically Typed ORM for VB and C# in about 160 Lines

Using the new DLR features in VB 10 and C# 4 you can build a configuration-free ORM that works well with legacy stored procedures. Though accessed using normal object-dot-property syntax, all the data objects are built at runtime based solely on the information returned by the database.

A Detailed look at Overriding the Equality Operator

It is surprisingly easy to make a mistake when overriding the equality operator. Not only does the equality operator bring along with it a lot of baggage, there is a lot of flawed guidance out there, even on the MSDN website. So we are going to try to clear the air by presenting a systematic breakdown of both a reference type and a value type that supports equality.
