I have created a project called DAL with Class file for accessing data and another web application project (inside same sln file)to consume the above mentioned class project. my class project needs to take connection string from config file and then establish the connection.

i add a reference on my class project file to my application project file and added

"using System.Data.SqlClient;
using System.Configuration; "

still im unable to access my class file inside my application project. Can you please see what else is missing?

should i add reference from class to application or is it the other way??

What do you mean unable?

They name spaces you show probably has nothing to do with your own project you reference. Did you put your own class under one of these name spaces? If not, these uses clauses are irrelevant.

When you add your .NET library to your other project, double click your reference on the Solution Explorer tree. You will be able to browse reflected referenced assembly. Do you see your class and its members you want to use? If not, check up if you use public access specifier for each type and member you need to make accessible to referencing assembly. When all declarations you need are available, use your declarations with fully-qualified names including their name space names. Or add using declarations, appropriate ones.

Good. Thanks for accepting this answer.
Good luck,
You need to be adding a class project reference to the application project.
Also, make sure your class is public and not internal.
