NET Core and Microsoft's cloud services, the Windows 10 operating system now includes an isolated development environment that enables you to share your Windows 10 PC with developers. ## What's New in.NET Core The.NET Core platform, which is no longer labeled as "preview," has been updated. While the primary goal of.NET Core is to enable you to develop cross-platform apps, there is a lot of new functionality for those who want to develop Windows apps. This includes: * A new Microsoft Visual Studio 2019 tooling experience with tooling that's easy to use and quick to get started. * Full access to.NET Core packages (for example, `HttpClient`). * Significant performance enhancements (for example, the `Stream` implementations), due to the use of the `Mono Framework` and `libuv` library. * Improved interoperability between.NET Core and other.NET platforms, such as.NET Framework, Windows Forms, WPF, and Xamarin. * Support for the Microsoft Azure cloud-service platform. * Improved Windows IoT Core support (especially for the Raspberry Pi). * The.NET Core CLI tool, which provides a native toolchain for cross-platform development. * Cross-platform development in C# and VB.NET in.NET Core 2.0 and Visual Studio 2019. * Added support for.NET Core on Linux. * Improved compatibility with.NET Framework (there is no version of.NET Framework supported for.NET Core). * Expanded accessibility support (for example, for disabled developers). * Cleaned up the API reference, which now uses a more consistent naming convention. * Improved performance of existing features. ## What's New in Visual Studio 2019 Visual Studio 2019 features a new user interface for developers. The updated tooling, known as the Microsoft Visual Studio 2019 experience, supports creating, debugging, and deploying apps across multiple platforms, including Windows, macOS, Linux, and more. It includes features for: * Creating, debugging, and deploying Windows apps. * Editing, testing, and building Windows apps on the desktop. * Debugging macOS and Linux apps on Mac and Linux. * Cross-platform debugging and deployment with macOS, Linux, and Windows.
