Whenever I insert PredicateFactory into the code the compiler generates an error

"Name 'PredicateFactory' is not declared"

All references are correct including sd.LLBLGen.Pro.ORMSupportClasses

This is a web project.

Any help will be much appreciated as this is driving me up the wall.

Thanks Sumeet

PredicateFactory is in the Factory Classes of your generated project. So If you named your generated classes BL try

BL.FactoryClasses.PredicateFactor

Or at the top of your code put for C#

using BL.FactoryClasses

Or VB.NET

Imports BL.FactoryClasses
