# .NET Core Roadmap

We aim to continuously deliver updates to the .NET Core Runtime and Tools.
We are primarily focused on delivering UWP 6.0 (.NET Standard 2.0 for UWP) and .NET Core 2.1.

We shipped .NET Core 2.0 and .NET Standard 2.0 - you can try it by installing [Visual Studio 2017 (15.3)][vs2017] and [.NET Core 2.0 SDK][Core20Sdk].

[vs2017]: https://www.visualstudio.com/downloads
[Core20Sdk]: https://www.microsoft.com/net/download/core

# Components

.NET Core is a general purpose, modular, cross-platform and open source implementation of .NET.
It includes a runtime, framework libraries, compilers and tools that support a variety of chip and OS targets.
These components can be used together or separately.

Major .NET Core components are listed below.
Please note that this is not meant to be an exhaustive list.

* [Runtime](https://github.com/dotnet/coreclr)
* [Libraries](https://github.com/dotnet/corefx)
* [.NET Standard](https://github.com/dotnet/standard)
* [C#/VB compiler](https://github.com/dotnet/roslyn)
* [F# compiler](https://github.com/microsoft/visualfsharp)
* [SDK](https://github.com/dotnet/sdk)
* [CLI tools](https://github.com/dotnet/cli) / [CLI documentation](https://docs.microsoft.com/en-us/dotnet/articles/core/tools/index)
* [NuGet](https://github.com/NuGet/Home)
* [ASP.NET](https://github.com/aspnet)
* [MSBuild](https://github.com/microsoft/msbuild)
* [Docker Images](https://github.com/dotnet/dotnet-docker)

This roadmap is intended to communicate project priorities for evolving and extending the scope of .NET Core.

There will be packages available for the native package managers for each OS.
(e.g. apt-get, rpm, pkg, msi) as well as zips.

Microsoft provides commercially reasonable support for ASP.NET Core 1.0, .NET
Core 1.0 and Entity Framework Core 1.0 on the OS and Version detailed in the
table above. Microsoft provides support for ASP.NET Core 1.0, .NET Core 1.0 and

# Project Goals

Broad goals:

* .NET Core code is high quality, has compelling performance, and is highly reliable.
* .NET Core can be ported to a broad set of OS platforms and chip architectures.
* .NET Core can be deployed with the application, side-by-side with other versions.
* .NET Core has a broad API surface that makes it suitable for most payloads.
* Developers can acquire a .NET Core developer environment quickly and intuitively.
* Developers can productively and intuitively build apps, using documentation, samples, community resources, and NuGet packages.

# Contributions

Contribution goals:

* Encourage an active community welcoming contributions from all.

The .NET Core maintainers have taken a liberal approach to contributions since the outset of the .NET Core open source project.

# Microsoft Distro

Microsoft ships multiple .NET Core distros.
It is important that Microsoft can successfully ship .NET Core at quality and meet its desired dates.

# Other Distros

.NET Core will ship as part of many Linux distros and we are actively working with key partners in the Linux community to make it natural for .NET Core to go everywhere people need it.
We are constantly looking to expand our distro support and welcome contributions and collaborations in this direction.

## Goals

* There are high-quality ports for Linux, macOS and Windows.
* There are high-quality ports for X64, X86, ARM32, and ARM64.
* .NET Core ships stable releases multiple times a year.
* Contributions should be prioritized that align with these goals.

## Workloads

The Microsoft distro currently supports the following workloads:

* Console Apps
* ASP.NET Core
* Windows 10 UWP
