Requirements
Besides understanding the more mundane aspects of C# and the .NET framework, you need to be well familiar with .NET REMOTING, Database (MS SQL), .NET Cryptography, SOAP, XML, ASP.NET and ADO.NET to follow this article and the corresponding code easily. Familiarity with the financial world is advantageous.
Objective
- The advent of C# and .NET has alleviated the design and development of applications to a completely new and MUCH BETTER!! Platform.
- In this article I will discuss some of the design and development issues that one might consider when using .NET framework for developing Network affiliated applications.
- The sample application is developed with the following issues in mind:
- Develop reusable components including the REMOTING and Cryptography modules;
- Provide easily configurable framework for local network access and develop components that could easily be reused to develop web services and applications accessible over the internet; and
- Provide a framework that better addresses performance and post release maintenance and enhancement issues.
Technology Coverage
- The implementation of the sample has touched almost all aspects of C# and .NET. These mainly include:
Serialization, Marshalling By Value and By Reference (MBV and MBR), Call Contexts, Threading, Events, Delegates, Reflection, Custom Attributes, Unsafe code (for including C++ style memory access), Remoting, Cryptography, UI and Configuration.
- For obvious reasons of space and for the sake of avoiding repetition, the detailed account of the underlying technology behind the code is not discussed. The discussion focuses on the design and implementation issues surrounding the overall framework of the application.
Overall Layout
- The application contains three major components; namely; Client side components, Server side components (remote objects) and secured Transport and Messaging components.
- The overall relationship between these components is depicted below:
