Icreon being an early adapter of the .NET framework was perhaps the first to presenta paper on the .NET framework in a conference hosted by Wiretrade and Microsoft inMauritius. Starting from system requirement to technologies, security issues andfuture of .Net framework was also discussed. Following points were discussed withthe team members, project managers so that they remain updated and ahead in thistech savvy database driven corporate world.
The .NET 3.0 is the latest version of the .NET Framework released by Microsoft. Itconcatenates .NET 2.0 Framework with other technologies resulting in uniformcommunication across various technologies that have visually alluring userexperiences. It can be used in combination with the following technologies:Â Windows Presentation Foundation (WPF) Â The API that is based on XML and vectorgraphics and aids in the development of the User Interface aspect of an application.
 Windows Communication Foundation (WCF)  The API which enables computers remainconnected by a network to communicate with each other. It combines Web Services,.NET Remoting, Distributed Transactions and Message Queues into a singe model.
 Windows Workflow Foundation (WF)  This technology enables developers to build andmanage workflow based applications. XAML a XML based language is used to define theworkflow structure.
 Windows CardSpace (WCS)  WCS is used to store and secure digital identities ofusers transacting over the Internet.SYSTEM REQUIREMENTSOperating Systems: Microsoft Windows 2003 SP1 or later, Windows XP SP2 or later,Windows Vista Hardware Requirements: 500 MB free hard disk space, 256 MB RAM, 1 GHz Pentium Processor
Enterprise Infrastructure
.NET provides a platform-independent structure for software development, withnumerous built-in features. It completely depends on software components and thecomponent based programming models.
The two principal components of .NET are the Common Language Infrastructure (CLI)and the Common Language Runtime (CLR). The CLI is a set of terms for a runtimeenvironment, which includes a common type system, Common Intermediate Language (CIL)code, which is machine independent and a base class library. The CLR offers aplatform for managing code that conforms to the CLI. The CLR translates the CIL intoa local machine code before its execution.
CIL is self-describing through .NET metadata. The metadata is checked by CLR to makesure that the correct method is being deployed. Developers are enabled to generatemetadata; though it is also generated by the language compilers in some cases. If alanguage implementation generates CIL, it can be hosted using the CLR and can theninteract with data produced by any other .NET language.
.NET Security mechanism has two basic features:
Code access security is evidence (the source of the assembly) oriented, which islinked with a particular assembly. It is either directly installed on the nativemachine or can be downloaded from the internet. Evidence is used by code accesssecurity to verify the permissions granted to the code. Other code can demand thatcalling code is granted a specified permission.
Validation & Verification are the two tests performed by CLR when the assembly isloaded. During the validation process the CLR verifies the presence of metadata &CIL and also verifies for the validity of internal tables. By deploying a fewalgorithms the verification mechanism checks if the code does any thing that is'unsafe'.
.NET LanguagesThe CLI has been designed in a way that it supports any OOP language by sharing acommon object model and a large common class library. Some of the languagessupported in .Net Framework are: C# 2.0, VB.NET 2005, J# 2.0, XAML, ASP.NET 2.0
Professionals also focused on the latest version, .NET 3.5 Orcas Beta 1 Framework.It features were summarized as: 3.5version includes a new compiler that supports Language Integrated Query(LINQ), as well as new language features in C# and VB.NET. ASP.NET AJAX can be deployed for creating more competent, effective andmore interactive and highly-personalized Web experiences that work across differentbrowsers. The new 3.5 beta version supports new web protocol for building WCFservices including AJAX, JSON, REST, POX, RSS, ATOM and several new WS-* standards Tools fully support for WF, WCF and WPF including the new workflow-enabledservices technology. New classes in the base class library (BCL) for the .NET Framework 3.5address the most common customer requests.
About Dot NET Framework, The .NET Framework is a software development platformdeveloped by Microsoft and is based on the use of a virtual machine that runs anIntermediate Language (IL). Codes/Programs are written to produce IL which isfurther distributed to users to run on virtual machines. C#, VB.NET and C++compilers are accessible from Microsoft for developing IL. .NET has given newfunctionalities and tools to the application programming interface. Theseimprovisations facilitate the process of developing applications for Windows, aswell as for web services. .NET framework provides a contemporary, insightful,object-oriented API. High flexibility standards have been implemented in its designto make it multi-language compatible. It has eased development of applications andreduced the security threats.
