.NET Product Roadmap

This document provides a peek into the work we've planned for .NET through December 2020.

The .NET product roadmap communicates project priorities for evolving and extending the scope of the product. New product experiences and features will include changes in various layers of the product, in some combination of the runtime, framework, language compilers and tools. Each component may have its own component-level roadmap that is available in the repository for that component.

These are some of the high level themes for the .NET 5.0 release. A more comprehensive list of the work we’re doing organized by technology can be found further below in this document.

  • Developers can build great cloud infrastructure components with .NET.
  • Developers can build great mobile apps for new devices with .NET 5 – we will support not only the latest in iOS and Android, but unify the platform and deliver first-class support for delivering cross-platform applications.
  • .NET 5.0 has excellent fundamentals - continue to deliver on reliability, performance, diagnosability, compliance, security, acquisition and deployment.

These are some key moments in our .NET 5.0 roadmap.

Date Moment/Rally Point Key Message
Sep 2020 Ignite
Nov 2020 .NET Conf .NET 5.0 Launch
Nov 2020 .NET 5.0 GA
