Hi,

My project architecture is as follows.
1- BE (Business Entites)
2- Web Application( Presentation Layer)
3- Wcf (Services Layer used to call dal and return result in the form of BE objects to presentation layer)
4 - Dal

I have class in the business entity layer which is used in the WCF layer too for input parameters and return types. When i add service reference to my web project and checked the check box reused types in referenced assemblies. Firstly , i got an issue service reference not found. If i unchecked this check box reused types in refulgence assemblies then service reference add but generated a class of business entity on its own. I do want to use only business entity objects in all application and why it is creating the new class on its own.
