      "Applicatio n Programming Interface". Often API is used as synonym for the
      Win32 API and 'Declare'/'DllImport' stuff, but in general even the .NET
      Framework is an API.

        As the .Net Framework is a layer from the OS than it cannot be an interface
        to that.

        In see definitly the .Net Framework as a layer from the OS.

          This doesn't mean it's not an API. API simply means "interface used to
          program an application". Check out the Wikipedia article in your post :-).

            Cor just loves to tease... ;-)

            But seriously, I would tend to agree with Cor that the .NET Framework
            does not fall into *generally* accepted meaning of the word API. I
            would distinguish the terms "framework" and "API". What are your
            thoughts on this ?

              Framework simply means a set of libraries, tools, etc. which can be used to
              develop applications, for example. API is more about what we get (an
              interface to parts of a system, application, library, whatever) to develop
              applications against, in other words, it's basically a contract). So, while
              the .NET Framework is a framework that includes libraries (which define an
              API), development and configuration tools, etc., the .NET Framework's class
              library provides an API.

                I would not say it like that, it is a part of the OS where against the CLI
                code can run.

                In my opinion is it the same is for every layer from an OS. That does not
                make them an API.

                The CLI code contains interfaces to that part of the OS but that does not
                make it an API.

                If you tell that inside this definition the classes distributed by the
                development part of the framework are API's than I am in more trouble to
                deny what you wrote. However that makes from every application itself almost
                an API. In my opinion is an API more restricted to one function from the OS.

                But just my thought,

                  The .NET Framework is not part of the OS. It's simply a layer that is built
                  on top of the OS core functionality.

                  It doesn't, but each layer can expose an API! Otherwise it would be
                  impossible to develop drivers, normal applications, etc. for Windows.

                  I am not sure what exactly you are referring to with CLI (typically this
                  stands for "Common Language Infrastructure" ).

                  No, I do not claim that. As I mentioned before, I see APIs as something
                  more abstract. A library is not the same as an API. An API consists of one
                  or more libraries which export functions, classes, etc., and are documented
                  and maybe specified, for example.

                  > However that makes from every application itself almost an API.[/color]

                  Not really. An application typically does not expose interfaces which can
                  be used by other developers to develop applications which inteact with the
                  application. However, there are some applications such as Word and Excel
                  which expose automation and extensibility functionality through APIs.

                    These two guys are so funny - API = Application Programming Interface.
                    It tells the whole story. It is an interface that can be used in the
                    programming of an application. It doesn't say anywhere that it has to
                    be made available by the OS. So, the OS, a component, a custom dll, all
                    can provide an API.

                    If your application is using the interface provided by some other code,
                    in your programming, then that is and API. Code is code. OS is just
                    code. Why get so caught up in insignificant details of where that code
                    resides?

                        We both told that in our first reply, where I gave a link Wikepedi which
                        explains it very good.

                        However there is nothing wrong as in a board something becomes a more
                        theoretical discussion.

                        That is where Usenet (NNTP) was build for.

                          Rather simplifying it, aren't you ! I think both of our veteran
                          specialists (I refrain from using the word "guys") have made such valid
                          points that I'm now confused. But not that it matters much.
