Extension of WCF-classes

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :SharePoint

For the client-application of a webservice we have the following requirements:

  • Client with WCF
  • SOAP-messages are signed and encrypted
  • The outgoing message should be logged. The logging must take place when the message is in the state signed and NOT encrypted.

We would like to use the AsymmetricSecurityBindingElement as base.


There is no configuration where you can only encrypt. 

Unfortunately it is also not possible to inherit from AsymmetricSecurityBindingElement, as AsymmetricSecurityBindingElement is marked as "sealed".



How do I get a "EncryptOnlyBindingElement" without implementing all the stuff from the beginning?

Actually all would be ready in WCF - but the relevant classes are marked "sealed" or "internal" :-(


The question considers only the client. The webservice is same Java stuff an can be considered as blackbox.


We would like to focus a solution like this:


class Ext_AsymmetricSecurityBindingElement : A

The Decorator Pattern & Extension Methods

The decorator pattern provides a formal way to add new functionality to an existing type, without sub-classing. First question: What is wrong with classical inheritance? In and of itself, nothing is wrong with the good old Is-A relationship. It is very common to derive a new class from an existing base class in order to override a few virtual members, and add a pinch of new functionality.

Learning C# and OOP, Classes

This is the second lesson in a miniseries designed to teach you how to write object-oriented programs using C#. This miniseries will describe and discuss the necessary and significant aspects of object-oriented programming (OOP) using C#.

The Decorator Pattern & Extension Methods

Numerous design patterns exist in the software world today, and ultimately nothing is preventing you from making your own (if people buy into it or not is another question). Furthermore, there is no 'master list' of patterns that all developers agree upon. While this is true, if you pick up any book on the subject, you will find a set of very common patterns most programmers agree are very useful. Many of these patterns were first formalized in the seminal book on the subject, Design Patterns: Elements of Reusable Object-Oriented Software (aka, the Gang of Four [GOF] book; not to be confused with the UK punk band of the same name).

C# 2.0: Create Elegant Code with Anonymous Methods, Iterators, and Partial Classes


C# 2.0 introduces a wealth of exiting new features, such as generics, iterators, partial classes and anonymous methods. While generics are the most talked-about feature especially for former classic C++ developers, the rest of the new features are important additions to your .NET development arsenal, enhancing power and improving overall productivity. This article is dedicated to all the new C# 2.0 capabilities besides generics to give you a good overall picture of the upcoming features.

Timers: Comparing the Timer Classes in the .NET Framework Class Library


Timers often play an important role in both client applications and server-based components (including Windows services). Writing effective timer-driven managed code requires a clear understanding of program flow and the subtleties of the .NET threading model. The .NET Framework Class Library provides three different timer classes: System.Windows.Forms.Timer, System.Timers.Timer, and System.Threading.Timer. Each of these classes has been designed and optimized for use in different situations. This article examines the three timer classes and helps you gain an understanding of how and when each class should be used.

Zip Your Data: Using the Zip Classes in the J# Class Libraries to Compress Files and Data with C#


Zip compression lets you save space and network bandwidth when storing files or sending them over the wire. In addition, you don't lose the directory structure of folders you Zip, which makes it a pretty useful compression scheme. The C# language doesn't have any classes that let you manipulate Zip files, but since .NET-targeted languages can share class implementations, and J# exposes classes in the java.util.zip namespace, you can get to those classes in your C# code. This article explains how to use the Microsoft J# class libraries to create an application in C# that compresses and decompresses Zip files. It also shows other unique parts of the J# runtime you can use from any .NET-compliant language to save some coding.
