.NET Core is a cross-platform, open-source framework for building modern, high-performance, and scalable applications. It is a redesign of the traditional .NET Framework and is optimized for cloud-based, microservices, and containerized applications. One of the key advantages of .NET Core is its ability to run on Windows, macOS, and Linux, which enables developers to build and run applications on various operating systems. This cross-platform capability enhances the flexibility and portability of .NET Core applications. Here's a code snippet illustrating a simple "Hello World" program in .NET Core: using System; class Program { static void Main() { Console.WriteLine("Hello, .NET Core!"); } } By leveraging .NET Core, developers can create powerful applications that cater to diverse environments and infrastructure. Its extensive support for modern application development, including web and cloud-native applications, makes it an essential framework in the .NET ecosystem.
