Complex .NET Remoting is the 1st publication out there that provides in-depth assurance of the .NET Remoting Framework. The ebook is split into sections&emdash;the first detailing the specifics of the framework and its functions in real-world functions. themes comprise formatters, channels, lifetime concerns, safeguard, configuration records, and the fundamentals of server-activated items as opposed to client-activated gadgets. additionally lined intimately are home windows providers, IIS, and server-side webhosting of remotable parts in console applications.
The moment a part of the publication offers an remarkable view of .NET Remoting internals. writer Ingo Rammer indicates how the framework makes use of message sinks and sink services, and offers in-depth guideline on find out how to enforce message and channel sinks. those chapters additionally provide perception into the synchronous and asynchronous message processing in the framework.
Going some distance past the data you are going to assemble from Microsoft's documentation, Rammer explains how .NET Remoting fairly works, and the way it may be prolonged. The publication additionally contains a bankruptcy at the improvement technique and resource code for numerous real-world message sinks, and indicates you ways to increase a customized Remoting delivery channel from scratch. It concludes with exact assurance of the ContextBoundObject classification and .NET contexts, crucial for utilizing the expertise inside of person, client-only purposes.

Sample text

Implimenting the Shared Assembly In the shared assembly, which is shown in Listing 3-19, you have to change the approch from using interfaces (which have been used in the prior examples) to abstract base classes because of the reasons stated previously. These are the superclasses of the classes you will implement in the two servers, therefore they have to descend from MarshalByRefObject as well. Listing 3-19: Using Abstract Base Classes in the Shared Assembly using System; Namespace General { public abstract class BaseRemoteObject: MarshalByRefObject { public abstract void setValue(int newval); public abstract int getValue(); } public abstract class BaseWorkerObject MarshalByRefObject { public abstract void doSomething(BaseRemoteObject usethis); } } The BaseRemoteObject's descendant is a Singleton located on the first server, and it allows the client to set and read an int as state information.

This gives you a huge advantage in that you don't have to distribute the implementation to the client system or manually tweak the output from SoapSuds -gc. Note Distributing the implementation to the client is not only a bad choice due to deployment issues, it also makes it possible for the client user to disassemble your object's codes using ILDASM or some other tool. You have to design your factory SAO using a shared assembly which contains the interface information (or abstract base classes) which are implemented by your remote objects.

This approach also gives you the huge advantage of being able to use configuration files for channels, objects, and the corresponding URLs (more on this in the next chapter) so that you don't have to hard code this information. In the following example, you can use the same server as in the previous example, only changing 58 Chapter 3: Remoting in Action Chapter 3: Remoting in Action 59 the SoapSuds command and implementing the client in a different way. Generating the Metadata with SoapSuds As you want to generate a metadata-only assembly, you have to pass the -nowp parameter to SoapSuds to keep it from generating a wrapped proxy (see Figure 3-34).
