Name

dotnet new install - installs a template package.

Synopsis

dotnet new install <PATH|NUGET_ID>  [--interactive] [--add-source|--nuget-source <SOURCE>] [--force] 
    [-d|--diagnostics] [--verbosity <LEVEL>] [-h|--help]

Description

The dotnet new install command installs a template package from the PATH or NUGET_ID provided. If you want to install a specific version or prerelease version of a template package, specify the version in the format <package-name>::<package-version>. By default, dotnet new passes * for the version, which represents the latest stable package version. For more information, see the Examples section.

If a version of the template package was already installed when you run this command, the template package will be updated to the specified version. If no version is specified, the package is updated to the latest stable version. Starting with .NET SDK 6.0.100, if the argument specifies the version, and that version of the NuGet package is already installed, it won't be reinstalled. If the argument is a PATH and it's already installed, it won't be reinstalled.

Prior to .NET SDK 6.0.100, template packages were managed individually for each .NET SDK version, including patch versions. For example, if you install the template package using dotnet new --install in .NET SDK 5.0.100, it will be installed only for .NET SDK 5.0.100. Templates from the package won't be available in other .NET SDK versions installed on your machine.

Starting with .NET SDK 6.0.100, installed template packages are available in later .NET SDK versions installed on your machine. A template package installed in .NET SDK 6.0.100 will also be available in .NET SDK 6.0.101, .NET SDK 6.0.200, and so on. However, these template packages won't be available in .NET SDK versions prior to .NET SDK 6.0.100. To use a template package installed in .NET SDK 6.0.100 or later in earlier .NET SDK versions, you need to install it using dotnet new install in that .NET SDK version.

Note

Starting with the .NET 7 SDK, the dotnet new syntax has changed:

The --list, --search, --install, and --uninstall options became list, search, install, and uninstall subcommands.
The --update-apply option became the update subcommand.
To use --update-check, use the update subcommand with the --check-only option.

Other options that were available before are still available to use with their respective subcommands. Separate help for each subcommand is available via the -h or --help option: dotnet new <subcommand> --help lists all supported options for the subcommand.

Additionally, tab completion is now available for dotnet new. It supports completion for installed template names and for the options a selected template provides. To activate tab completion for the .NET SDK, see Enable tab completion.

Examples of old syntax:

Install the latest version of Azure web jobs project template package:
```
dotnet new --install Microsoft.Azure.WebJobs.ProjectTemplates
```

Arguments

<PATH|NUGET_ID>

The folder on the file system or the NuGet package identifier to install the template package from. dotnet new attempts to install the NuGet package from the NuGet sources available for the current working directory and the sources specified via the --add-source option. If you want to install a specific version or prerelease version of a template package from NuGet source, specify the version in the format <package-name>::<package-version>.

Options

--add-source|--nuget-source <SOURCE>

By default, dotnet new install uses the hierarchy of NuGet configuration files from the current directory to determine the NuGet source the package can be installed from. If --nuget-source is specified, the source will be added to the list of sources to be checked.
To check the configured sources for the current directory use dotnet nuget list source. For more information, see Common NuGet Configurations

Note

Following NuGet's Https Everywhere initiative, dotnet new is phasing out http feeds. If an http feed is passed, it isn't queried for packages and a warning is displayed. The --force option can be used to override this behavior if necessary.
-d|--diagnostics

Enables diagnostic output. Available since .NET SDK 7.0.100.
--force

Allows installing template packages from the specified sources even if they would override a template package from another source. Available since .NET SDK 7.0.100.
-h|--help

Prints out help for the install command. Available since .NET SDK 7.0.100.

--interactive

Allows the command to stop and wait for user input or action. For example, to complete authentication. Available since .NET 5.0 SDK.

-v|--verbosity <LEVEL>

Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], and diag[nostic]. Available since .NET SDK 7.0.100.
