Chapter 2. .NET Core Overview
.NET Core is a general purpose, modular, cross-platform, and open source implementation of .NET that features automatic memory management and modern programming languages. It allows users to build high-quality applications efficiently. .NET Core is available for Red Hat Enterprise Linux (RHEL) 7 and RHEL 8.
This release of .NET Core adds support for C# 8, a new major release of the C# language, and building Windows desktop applications (on Windows). The release improves build and runtime performance. The SDK supports publishing applications into a single file (PublishSingleFile), trimming unused assemblies to reduce the size (PublishTrimmed), and ahead-of-time (AOT) compilation to improve startup time (PublishReadyToRun). New APIs are available for improved performance, including a new JSON API (System.Text.Json) and accessing hardware intrinsics (System.Runtime.Intrinsics).
.NET Core offers:
- the ability to follow a microservices-based approach, where some components are built with .NET and others with Java, but all can run on a common, supported platform in RHEL.
- the capacity to more easily develop new .NET Core workloads on Microsoft Windows. Customers can deploy and run on either RHEL or Windows Server.
- a heterogeneous data center, where the underlying infrastructure is capable of running .NET applications without having to rely solely on Windows Server.
