The .NET Core Docker images 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".

Installing 3.0 Previews on Linux

Snap is the preferred way to install and try .NET Core previews on Linux distributions that support Snap.

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 for details.

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-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.

You can’t perform that action at this time.
