.NET Core - Version History

In this article, I will explain the ASP.NET Core web API Versions and new features. The American multinational technology corporation Microsoft recently announced the latest version of .NET, which is .NET 7.

.NET Core Web API Introduction

.NET Core is a free, open-source, cross-platform framework developed by Microsoft for building modern applications. It is a modular and lightweight platform that allows developers to build applications that run on Windows, macOS, and Linux.

Here are some key Characteristics or features of .NET Core.

  1. Cross-platform - .NET Core is designed to be cross-platform, meaning you can develop and run applications on multiple operating systems, including Windows, macOS, and Linux. This allows for greater flexibility and reach for your applications.
  2. Open-source - .NET Core is an open-source framework and is developed in collaboration with the .NET community. This means that developers have access to the source code, can contribute to the framework, and benefit from community-driven enhancements and bug fixes.
  3. Modular and Lightweight - .NET Core follows a modular design, with its functionality split into smaller packages called NuGet packages. This modular approach allows developers to include only the necessary components in their applications, resulting in smaller and more efficient deployments.
  4. High Performance - .NET Core is optimized for performance and is known for its fast startup times and efficient resource utilization. It includes features such as Just-in-Time (JIT) compilation, which dynamically compiles code for execution, and Ahead-of-Time (AOT) compilation, which pre-compiles code for even faster startup.
  5. Language Support - .NET Core supports multiple programming languages, including C#, F#, and Visual Basic. This allows developers to choose their preferred language for application development while leveraging the power and capabilities of the .NET platform.
  6. Integration with Visual Studio - .NET Core integrates seamlessly with Microsoft's popular integrated development environment (IDE), Visual Studio. Developers can leverage Visual Studio's rich set of tools and features for code editing, debugging, testing, and deployment of .NET Core applications.
  7. Long-Term Support (LTS) Versions - Starting with .NET Core 3.1, Microsoft introduced Long-Term Support (LTS) versions of .NET Core. These LTS versions receive three years of support and are recommended for applications that require stability and long-term maintenance.
  8. Migration Path from .NET Framework - For developers with existing .NET Framework applications, Microsoft provides tools and guidance for migrating to .NET Core. This allows you to modernize your applications and take advantage of the benefits and features offered by .NET Core.
