.NET 5.0.0

.NET 5.0.0 comprises:

  • .NET Runtime 5.0.0-rtm.20519.4
  • ASP.NET Core 5.0.0-rtm.20526.5
  • .NET SDK 5.0.100-rtm.20526.5

See the Release Notes for details about what is included in this update.

Docker

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

Install .NET on Linux

Install using Snap

Because of the isolated environment, using Snap is the preferred way to install and try .NET on Linux distributions that support Snap.

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

sudo snap install dotnet-sdk --channel=5.0/stable --classic

Some systems require that you restart the terminal session so the Snap install location can be added to the path. If this is the case, you will see a warning once the dotnet-sdk Snap installation is complete.

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

Note: Some distributions 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 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

Note: Before updating to .NET 5.0, uninstall any preview versions of .NET 5.0 you have previously installed.

Develop applications

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

sudo [package manager] update or refresh
sudo [package manager] install dotnet-sdk-5.0

Run applications

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

sudo [package manager] update or refresh
sudo [package manager] install aspnetcore-runtime-5.0

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

Windows Server Hosting

If you are looking to host stand-alone 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:

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