A Detailed Overview of .Net Development

If you are one among those million IT professionals who always hunt for the opportunity to bring the most productive project in your kitty, then you must be quite familiar with the eminence of keeping yourself up to date with the recent technologies knocking hard on the IT door.

Which is the highly preferred and profitable technology:

This is one of the most searched questions on Google and the answer is either .Net technology or iOS development. Further, adding more to this, iOS development is high on competition bars whereas there is always a scarcity of proficient .Net developers in a comparison to the actual requirement. Eventually, this has accelerated the demand of .Net developers on global levels.

Let’s dive deeper and unravel the actual meaning of .Net development.

What is .Net (pronounced as Dot Net) Development?

Just like any other, .Net technology is a programming language used to accomplish the different development tasks including- web application, mobile applications, windows app, and console. It is basically, a framework allowing the developer to construct a code structure for different platforms. It runs on two major frameworks naming-

1.    .Net Framework Class Library (FCL)

2.    Common Language Runtime

And if asked in a layman’s language, it is basically a toolkit for .Net developers having different interface codes and approachable designs to simplify the overall web app, mobile app development process. Just like any plumber may need a pipe holder or mole grips to fix a leaky tap, same is the case with a developer. However, the type, shape or purpose of tools may vary but the reason is similar- to simplify work approach and come up with accurate results. All it demands is, it’s particular framework without which the .Net technology code structure doesn’t work anyhow.

Why .Net is a preferred technology?

Only those who have been associated with this industry know how effective and secured .Net technology is. It simplifies and fastens the process of developing applications for any platform (web, mobile or windows). Apart from speedy results, it assures quick solution to any coding bug, if found.

The background of .Net technology:

This process started in the late 1990s when Microsoft began working on developing .Net technology framework. Initially, the framework was developed as a part of overall .Net strategy under the project name of ‘(NGWS) Next Generation Windows Services.’ Continuing the development process, finally, in late 2000, Microsoft launched the first ever beta version of the .net technology named as ‘.Net 1.0.’

Later, in August, 2000, Intel, Hewlett-Packard and Microsoft collaborated to upsurge CLI (Common Language Infrastructure) and C#. And by December 2011, both the languages (CLI (Common Language Infrastructure) and C#) were acclaimed with (ECMA) ECMA International Standards.

To strengthen the patent protocol, on 3rd October 2007, Microsoft declared that the .Net framework 3.5 libraries source code will be accessible under the Microsoft Reference Source License. Resulting, on 16th January 2008, the source code including ADO.NET, Windows Forms, WPF, XML, BCL, ASP.NET was available, as promised. To this, Scott Guthrie (an Executive Vice President of the Cloud and Enterprise group in Microsoft), added that soon WCF, LINQ and WF libraries will be amended to the overall setup by Microsoft.

On 12th November 2014, Microsoft declared another invention named .Net Core. The industry saw it as an effort to support the cross-platform technology of .Net. To this, Immo Landwerth (Program manager on .NET at Microsoft) explained .Net Core as "the foundation of all future .NET platforms".

Here is a detailed table to explain a crystal-clear outline of Microsoft’s .Net technology releases.

What does the basic architecture of .Net development includes?

Common Language Infrastructure

The basic function of this infrastructure is to provide a language-neutral platform for the applications (developed or under-development) to assist in application execution. Once, CLI (Common Language Infrastructure) is implemented, it gives the developer complete authority to access the developed application in different languages which has been deployed in the .Net framework.

Common Language Runtime

Also known as the execution engine of .Net framework, CLR (Common Language Runtime) opens the gateway to many development aspects including- garbage collection, type safety, memory management, thread management, and exception handling). In order to get access on all such development measures, it is important to deploy them on the .Net framework, first.

Class Library

The overall .net framework includes a number of standard class libraries which are organized in a hierarchical manner under the namespaces segment. In libraries, the highest number of built-in APIs (Application Programming Interface) is a section of either Microsoft.* or System.* namespaces. The basic function of including such libraries in the .Net framework is to simplify the execution of common yet necessary functions including- graphics rendering, reading or writing the script, XML document manipulation, and database interaction. These libraries differ for every language available in the .Net framework and can be chosen accordingly.

In general, the libraries are divided into two different segments including- Framework Class Library (FCL) and Base Class library (BCL).

What is FCL (Framework Class Library)?

FCL is a major set of BCL containing the overall class or library which initiates the .Net framework process. It may also include- Windows Forms, (WPF) Windows Presentation Foundation and ASP.NET.

What is BCL (Base Class Library)?

The grounded function of BCL is to work as the elementary API of CLR (Common Language Runtime). Most of the formations made under BCL are written as- mscorlib.dll, System.dll, and System.Core.dl. BCL is present in almost every sort of .Net development framework and in its different classes including- .Net Core, Mono, Microsoft Silverlight, and Compact Framework.


In a .Net framework, there are different sets of assemblies enabling multiple features or functions. Within each assembly, there are one or more files containing the basic metadata having information on different elements including- simple text name, public key token, version number, and culture.

Adding further, there is a private key used by the developers to create a strong naming assembly if required. With the help of a public key token, the combination of private key and assembly can be analyzed easily. In order to add assemblies to the Global Assembly Cache, the strong naming of each and every assembly available in the .Net framework is mandatory.


With the introduction of C++/CLI in the Visual Studio, 2005, Microsoft launched a new programming language meant to comply programs and make them run fluently within the realms of .Net development framework. There are different assemblies within the .Net framework which is developed using C++/CLI and contains native as well as managed code in a single DLL so they are considered as mixed-mode assemblies. However, it helps to simplify the coding approach but at the same time is a bit tricky as compared to other ordinary assemblies.

App modes:

The basic function of app modes is to assist the mobile app development process. Under .Net framework, app modes support different elements including- Windows Presentation Foundation (WPF), ASP.NET and console.

In order to accomplish a .Net development project successfully, there is a lot more than just working on the .Net framework. Amid all aspects, one basic and necessary element design. Here is a string of design fundamentals which are important to be followed.

Language independence:

.Net framework is eligible to support the exchange of example objects and types revolving between the different libraries and applications developed and written using specifically.Net language.


Usually, the .Net technology framework contains its own security measures and mechanism which includes- validation, verification and CAS (Code Access Security). Basically, CAS collects the database of different assemblies associated with the .Net framework and work as an evidence. If one has to read or see the code used behind the .Net framework, it is CAS which grants the permission, if it is a genuine request. CAS is considered to be important with the intent of safeguarding the trade secrets and code structure of the business website.

Type safety:

CLR (Common Language Runtime) and CTS (Common Type System) are two different types of enforced type safety available in the .Net framework. It is used to eradicate the presence of any wrong approach, inappropriate code method, memory size or any other unusual element present in the overall code structure. But with the invention of .Net framework 4.0, the Dynamic Language Runtime has exaggerated the scope and functioning of CLR making it more prominent component of the entire code structure.

Overall performance:

At the launch of a mobile application, the .net framework combines into CIL code structure with the help of ‘just-in-time compiler’ and then processes the database cache and the leftover execution procedure within the .Net Native Image Cache. With this, the process of launching application fastens. In order to come to ensure its success, developers often use Native Image Generator. Apart from this, including, the garbage collector, in this process is another smart medium to fasten the performance which targets the unanticipated loopholes delaying the process. And the best thing about this garbage collector is that the developer can have direct access to it. .Net framework also helps in integrating the Streaming SIMD Extensions (SSE) through the managed code introduced in Visual Studio 2013.

Memory management:

In the entire .Net framework, it is CLR (Common Language Runtime) that waves off all the worries of a developer, in terms of managing the memory and allocating it safely. Right from, restoring multiple elements to analyzing their exact allocation, CLR solely handles it. Common Language Runtime identifies the loopholes and converts them into the garbage and end up eradicating them from the code structure. To simplify this process, CLR is always in need of a (GC) garbage collector, available within the .Net framework. In the improvised .Net technology frameworks, the garbage collector starts to wipe off the unwanted elements from the code structure, when rectifies the system is detecting high pressure on the memory segment. While the garbage collector automates the process, usually the system stops functioning.


Initially, Microsoft never implemented a full-stack .Net development framework in any specific system (except in the Microsoft Windows) but later, Microsoft created a specific framework for different cross-platform and made it available for the operating systems to access.

The bottom line:

This writes up is purely dedicated to Microsoft introduced .Net (pronounced as Dot Net) development technology. Right from the literal meaning to its origin background, it covers every minutiae detail of .Net. The biggest highlight of this article is the designing principles which smartly adds value to the overall .Net development structure.
