I am a rookie for .NET.

I am using a class library for a web application.
If I make any change to library code and compile, do I need to replace the dll in application bin directory explicitely every time?
Is there any other work around for this, like - when I change library code, appropriately latest dll is referred?

Moreover, when I try to debug the project, F11 doesnt take me to library function. Instead, control goes to next line immediately executing that function. I've set both Library and Project to Debug mode and both are in the same solution.

Also, Please tell me fundamentals of dll.
I understand that, when I compile any project, dll is created/refreshed. Is this related to only classes in that project or some other components also?
