.NET is a free, cross-platform, open source developer platform for building many different types of applications.
What is DOT NET?
The .NET is the technology from Microsoft, on which all other Microsoft technologies will be depending on in future. It is a major technology change, introduced by Microsoft, to catch the market from the SUN’s Java. Few years back, Microsoft had only VC++ and VB to compete with Java, but Java was catching the market very fast. With the world depending more and more on the Internet/ Web and java related tools becoming the best choice for the web applications, Microsoft seemed to be loosing the battle. Thousands of programmers moved to java from VC++ and VB. To recover the .market, .Microsoft announced .NET.
Microsoft’s VC++ was a powerful tool. But it was too complex. It has too many data types, and developers had to learn many libraries including Windows SDK, MFC, ATL, COM etc. There were many data type compatibility issues while exchanging data between different layers. Visual Basic was too easy, and many serious programmers hated it just for that reason. Even though Visual basic was very easy to use, it was not very flexible to develop serious applications. SUN’s Java became a very good choice for these reasons. It had the flexibility and power of C++ and at the same time easy enough to catch the attention of VB programmers. It is used for:
FEATURES OF DOT NET
Whether you’re working in C#, F#, or Visual Basic, your code will run natively on any compatible OS. Different .NET implementations handle the heavy lifting for you: .NET Core is a cross-platform .NET implementation for websites, servers, and console apps on Windows, Linux, and macOS. .NET Framework supports websites, services, desktop apps, and more on Windows. Xamarin/Mono is a .NET implementation for running apps on all the major mobile operating systems.
To extend functionality, Microsoft and others maintain a healthy package ecosystem built on .NET Standard. NuGet is a package manager built specifically for .NET that contains over 90,000 packages.
Browser compatibility can be easily overlooked. Even the websites of some of the most reputable companies suffer from this problem due to neglect. This is bad for branding and has a negative affect on website usability. Although modern browsers have evolved and become more efficient, some inconsistencies still exist in how a website is interpreted by different browsers.
One consistent API
.NET Standard is a base set of APIs that are common to all .NET implementations. Each implementation can also expose additional APIs that are specific to the operating systems it runs on. For example, .NET Framework is a Windows-only .NET implementation that includes APIs for accessing the Windows Registry.
Active community and open-source
.NET is open source and under the .NET Foundation. The .NET Foundation is an independent organization to foster open development and collaboration around the .NET ecosystem. Because .NET is open source, you can join the 60,000 developers and 3,700 companies already contributing to the .NET platform.
