ASP.NET also acts as a host for remoted components. The Remoting handler is automatically mapped to requests of files with extensions of .soap or .rem via a configuration document that gets added to the root of your web application, requests of specific network endpoints are mapped to types living in assemblies in the application s bin directory. Discussions about Remoting internals are beyond the scope of this book (see Tom Barnaby s book, Distributed .NET Programming in C# (Apress, 2002) for excellent coverage). However, in this chapter, we ll still take a look at a couple of ways .NET types can be exposed via Remoting. Here s a simple type that by inheriting from MarshalByRefObject is pinned in the process it s created within; and so it can be called via Remoting. class BookService : MarshalByRefObject { public DataTable getBookList() { SqlConnection cn = new SqlConnection(connStr); SqlCommand cm = new SqlCommand( "select BookID, Title From Book Order by Title", cn); DataTable dt = new DataTable(); try { cn.Open(); dt.Load(cm.ExecuteReader()); return dt; } catch { } finally { if (cn.State == ConnectionState.Open) cn.Close(); } } }

This component then can be exposed via ASP .NET using the following entry in the web.config of an IIS application: <system.runtime.remoting> <application> <service> <wellknown mode="Singleton" type="BookLib.BookService, BookLib" objectUri="BookService.soap" /> </service> <channels> <channel port="13101" ref="http" /> </channels> </application> </system.runtime.remoting> The client requires a configuration file to use the remoted type. Here s a configuration file you can use as the app.config for a simple console application: <system.runtime.remoting> <application> <client displayName="BookService"> <wellknown type="BookLib.BookService, BookLib" url="http://localhost:13101/BookHost/BookService.soap" /> </client> <channels> <channel ref="http" /> </channels> </application> </system.runtime.remoting> And here s the code for a console application consuming this remoted type: static void Main(string[] args) { // Load the remoting config file RemotingConfiguration.Configure("BookClient.exe.config"); // Now connect to the remote object by simply using its constructor! BookLib.BookService b = new BookLib.BookService(); DataTable dt = b.getBookList(); foreach (DataRow dr in dt.Rows) Console.WriteLine(dr["Title"]);

The limitation of exposing remoted types via ASP .NET is that you must use HTTP as the transport protocol. If you want to use TCP you have to write your own listener instead of rely, ing on ASP .NET. See the section Custom Listeners later in this chapter for an example of doing this with a Windows Service.

When you re using Serviced Components, you ll want to consider how they ll be exposed. You can do this via either Web Services or Remoting. These choices are independent from one another; that is, there is nothing in a decision to use Serviced Components that ties you to using either Web Services or Remoting. These are your choices when exposing your Serviced Components via ASP .NET. However, they are not your only choices. As you ll see in the sections that follow, you still have the option of using traditional DCOM and COM interop to get to Serviced Components; and with Windows XP and Windows 2003, they can be exposed directly as Web Services. The salient point in hosting Serviced Components always comes back to the ApplicationActivation attribute. This is the assembly-level attribute we discussed in 7. //Use this for DllHost.exe [assembly: ApplicationActivation(ActivationOption.Server)] //or this for hosting in the process of the creator [assembly: ApplicationActivation(ActivationOption.Library)] This is the attribute that determines how your Serviced Components will be hosted. Keep in mind that a server application can call components in a library application, and those types will then be created in the DllHost process dedicated to the server application. DllHost.exe actually hosts an instance of the Common Language Runtime (CLR), within which it can execute Serviced Components. When calling a Library application from IIS, types are created in process with the calling worker process (w3wp.exe for IIS6, aspnet_wp.exe for IIS5.x). If you have several IIS applications calling library applications in COM+, they will each be created in the process of the caller, resulting in thread pools, connection pools, and object pools for each of your IIS applications.
