architecture of project
i make a new web site and add new project classlibraryinto it and named it as test.datalayer
then i add new class library and name it as test.businesslayer
i added one more inbuilt folder in web site Bin
then i built project
i added reference of test.datalayer into test.businesslayer and after this when i add reference of businesslayer into web site then in bin folder both both business alyer and datalaer's dll added.
Now i can access classes of both businesslayer as well as datalayer in my web site which i donot want. i want only of business layer.
