Visual Studio Compatibility

This update for .NET Core 2.1 includes multiple SDK builds. If you are a Visual Studio 2019, Visual Studio 2017 or Visual Studio for Mac user, there are MSBuild version requirements that are satisfied by specific, matching .NET Core SDK versions. See the table below to select the correct download.

OS	Development Environment	.NET Core SDK
Windows	Visual Studio 2017	2.1.524
macOS	Visual Studio for Mac	Visual Studio for Mac .NET Core Support

Docker

The .NET Core Docker images have been updated for this release. The .NET Docker samples show various ways to use .NET and Docker together.

Installing .NET Core on Linux

Install using Snap

Snap is a system which installs applications in an isolated environment and provides for automatic updates. Many distributions which are not directly supported by .NET Core can use Snaps to install. See the list of distributions supported Snap for details.

After configuring Snap on your system, run the following command to install the latest .NET Core SDK.

sudo snap install dotnet-sdk --channel 2.1/stable –-classic

When .NET Core in installed using the Snap package, the default .NET Core command is dotnet-sdk.dotnet, as opposed to just dotnet. The benefit of the namespaced command is that it won't conflict with a globally installed .NET Core version you may have. This command can be aliased to dotnet with:

sudo snap alias dotnet-sdk.dotnet dotnet

Note: Some distros require an additional step to enable access to the SSL certificate. If you experience SSL errors when running dotnet restore, see Linux Setup for a possible resolution.

Install using a Package Manager

Before installing .NET, you need to register the Microsoft key, register the product repository, and install required dependencies. This only needs to be done once per machine. Refer to Setting up Linux for .NET Core for the requirements.

The following commands don't specifically include package managers to help with readability. Here are the package managers typically used by the distros on which .NET Core is supported.

Distro	Package Manager
CentOS, Oracle	yum
Debian, Ubuntu	apt-get
Fedora	dnf
OpenSUSE, SLES	zypper

Develop applications

To develop applications using the .NET Core SDK, run the following command. The .NET Core runtime and ASP.NET Core runtime are included.

sudo [package manager] update or refresh
sudo [package manager] install dotnet-sdk-2.1

Run applications

If you only need to run existing applications, run the following command. The .NET Core runtime and ASP.NET Core runtime are included.

sudo [package manager] update or refresh
sudo [package manager] install aspnetcore-runtime-2.1

Installation from a binary archive

Installing from the packages detailed above is recommended or you can install from binary archive, if that better suits your needs. When using binary archives to install, the contents must be extracted to a user location such as $HOME/dotnet, a symbolic link created for dotnet and a few dependencies installed. Dependency requirements can be seen in the Linux System Prerequisites document.

mkdir -p $HOME/dotnet && tar zxf dotnet.tar.gz -C $HOME/dotnet
export PATH=$PATH:$HOME/dotnet

.NET Core Runtime-only installation

If only the .NET Core Runtime is needed, install dotnet-runtime-2.1 using your package manager. If you also need ASP.NET Core functionality, installing aspnetcore-runtime-2.1 will install both the ASP.NET Core Runtime and .NET Core Runtime.

Windows Server Hosting

If you're looking to host standalone apps on servers, the following installer can be used on Windows systems.

Windows

You can download the Windows Server Hosting installer and run the following command from an Administrator command prompt:

• dotnet-hosting-2.1.28-win.exe

This will install the ASP.NET Core Module for IIS.
