Your ISP must first create an IIS application and apply the Front Page Server Extensions to it. Then in Visual Studio.NET, select the "Project | Copy Project" menu. Then enter the URL and select the FrontPage web access method. The "Copy Project" feature copies all of the necessary files to your ISP's machine for your ASP.NET application to run.

What Is The Difference Between Src And Code-behind?
Src attribute means you deploy the source code files and everything is compiled JIT (just-in-time) as needed. Many people prefer this since they don't have to manually worry about compiling and messing with dlls -- it just works. Of course, the source is now on the server, for anyone with access to the server -- but not just anyone on the web.
CodeBehind attribute doesn't really "do" anything, its just a helper for VS.NET to associate the code file with the aspx file. This is necessary since VS.NET automates the pre-compiling that is harder by hand, and therefore the Src attribute is also gone. Now there is only a dll to deploy, no source, so it is certainly better protected, although its always decompilable even then.

You can do this using assembly directives.

<%@ assembly src="test2.cs" %>
However, note that each source file will be compiled individually into its own assembly, so they cannot have dependencies on each other.
