1. Includes the .NET Core and ASP.NET Core Runtimes
2. For hosting stand-alone apps on Windows Servers. Includes the ASP.NET Core Module for IIS and can be installed separately on servers without installing .NET Core runtime.

## Docker

The [.NET Core Docker images](https://hub.docker.com/r/microsoft/dotnet/) have been updated for this release. Details on our Docker versioning and how to work with the images can be seen in ["Staying up-to-date with .NET Container Images"](https://blogs.msdn.microsoft.com/dotnet/2018/06/18/staying-up-to-date-with-net-container-images/).

## Installing .NET Core 3.0 Previews on Linux

Snap is the preferred way to install and try .NET Core previews on [Linux distributions that support Snap](https://docs.snapcraft.io/installing-snapd/6735).

After configuring Snap on your system, run the following command to install the .NET Core SDK 3.0 Preview.

`sudo snap install dotnet-sdk --beta --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 will not 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`

Some distros require an additional step to enable access to the SSL certificate. See [Linux Setup](https://github.com/dotnet/core/blob/master/Documentation/linux-setup.md) for details.

### Installation from a binary archive

You can also 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](https://github.com/dotnet/core/blob/master/Documentation/linux-prereqs.md) document.

```bash
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-3.0` using your package manager. If you also need ASP.NET Core functionality, installing `aspnetcore-runtime-3.0` will install both the ASP Runtime and .NET Core Runtime.

## Windows Server Hosting

If you are looking to host stand-alone apps on Servers, the following installers can be used on Windows and Linux systems.

### Windows

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

* [dotnet-hosting-3.0.0-preview-19075-0444-win.exe][dotnet-hosting-win.exe]

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