XSD to C# class or VB.net class

While working with biztalk using web services i found this as a must to have tool.
The XSD.exe from microsoft can be used for this.

The Sample Code Generator (XSDObjectGen) tool takes an XSD schema as input and generates sample code showing how to mark up C# and VB.Net classes so that when serialized with the XML serializer, the resulting XML will be valid according to the original schema.
