ASP.NET Core offers a number of advantages over the original ASP.NET framework, including improved performance, cross-platform support, supported platform, and simplified development. If you're looking to build a web application that is high-performing and can be deployed across multiple platforms, then ASP.NET Core is the framework for you. Improved performance One of the biggest advantages of ASP.NET Core is its performance. Thanks to its smaller footprint and improved architecture, ASP.NET Core applications are able to handle more requests per second and have faster startup times. The great performance of ASP.NET Core was evident in the TechEmpower Round 20 benchmark test. Cross-platform support Another major benefit of ASP.NET Core is its cross-platform support. Unlike the original ASP.NET framework, which could only be used on Windows, ASP.NET Core applications can also be developed and run on macOS, Linux, and Docker. This makes it a great choice for companies that want to deploy their applications across multiple platforms. To help developers across different operating systems, Visual Studio products now includes tools for building .NET applications on any operating system. Supported and innovative platform ASP.NET Core replaces ASP.NET and thus is the version to be used if you want to ensure that your applications run on a supported platform that is continuously developed upon. Some versions of ASP.NET do still receive minor updates, patch releases, and bug fixes, but will no longer receive any major new features. All innovation and further development only happen in ASP.NET Core, and thus it’s the version to use if you want to take advantage of the newest technologies and features available for .NET applications. Simplified development experience Finally, ASP.NET Core offers a simplified development experience. The new framework is easier to learn and use than the older version, making it a good choice for developers who are new to web development.
