I am newbie in .net.Today I have created a sample. In that sample, I have stored data in database using N Tier architecture. If I want to use to Use BL or DAL method in other project(I mean BL method in UI or DAL method in BL), I found two ways.

First one is – Right click on project << Add Reference << Select Project in Project tab

Second one is – Right click on project << Add Reference << Select DLL in Browse tab

Could anyone tell me that is there any difference between both of them as both works same.Is DLL way better then Project Reference.If yes, then what is the benefits?

Thanks in advance.

Mohit Kumar.

    The correct way to do it is to add a project reference.
    one of the most important differences is that a project reference is updated automatically when you change the referenced project.
    for example- If you change your DAL method from GetEmployees() to GetAllEmployees() then you can use GetAllEmployees() immediately in your BL class, without compiling your DAL first.
