List of namespaces and dll

Is there a list of dll and namespaces vs control and objects included in a page?

For example, I yet lerned that if I use a DataBase componets it is necesary to use:

System

System.Data

System.Data.SQLClient

I also lerned that the first two are dll and are located in the Framework directory, and that SQLClient is not a dll but it is included in System.Data.

I would like to have a complete list of dll, its uses and what each one contains

Included with my VS2005 Professional was a poster intitled "Microsoft .NET Framework 2.0 - Commonly Used Types and Namespaces." I have it up on the wall behind my desk and refer to it for questions like that. You might search the kb or msdn for the same thing online.

You don't need to know the name of each dll. System and System.Data are namespace. If you want to use a class that is in SQLClient you have to write System.Data.SQLClient.AClass. This would be long to write every time so to speed things up you can import the namespace and everything in that namespace can be used. If you want to have the entire list for quick reference, use the chart. If you don't know in which namespace a class is in, check the help file.
