Introduction to .NET Development
.NET is a free, open-source, and cross-platform software development platform created by Microsoft to help developers build a wide range of applications, from web and mobile apps to desktop software and cloud solutions. It is a popular choice among developers because it supports running multiple languages and helps developers to build high-performance and scalable apps.
The .NET was initially introduced in the back 1990s, as NGWS (Next Generation Windows Services). Microsoft created this with the goal of creating a unified platform for building all types of applications.
Then in 2000, .NET Framework’s beta version 1.0 was out and the first official version was launched in 2002.
In 2005, version 2.0 was released with features like Windows Forms 2.0, ASP.NET 2.0, and WCF.
Version 3.0 was released in 2006, and then Microsoft gradually released upgraded versions after a few years with improvements and advanced functions.
Over the years, .NET has evolved into a modern, high-performance, and flexible platform. Today, developers are using it to create powerful applications for Windows, Linux, macOS, Android, and iOS.
What are the main components of the .NET Framework?
CLR and FCL are the two main components of the .NET Framework.
CLR is a common language runtime that is responsible for processing, running the code, and managing other services. It runs two types of code- managed and unmanaged code. The code that CLR compiles and executes is managed code, and the code that is not compiled or managed by CLR is known as unmanaged code.
FCL refers to the framework class library that includes various classes, methods, and libraries that can be reused in code during application development.
Evolution of .NET technologies
Before the final release of .NET technology, it evolved in three phases:
- OLE technology means object linking and embedding. It was used to link components and elements from and to different applications.
- COM technology means Common Object Model. It allows developers to create various reusable components in different programming languages and link each other.
- And then .NET technology was released in feb 2002 as a next-generation web services.
How does .NET align with modern business goals?
