Name

dotnet new - Creates a new project, configuration file, or solution based on the specified template.

Synopsis

dotnet new <TEMPLATE> [--dry-run] [--force] [-i|--install] [-lang|--language] [-n|--name] [--nuget-source] [-o|--output] [-u|--uninstall] [Template options]
dotnet new <TEMPLATE> [-l|--list] [--type]
dotnet new [-h|--help]

Description

The dotnet new command provides a convenient way to initialize a valid .NET Core project.

The command calls the template engine to create the artifacts on disk based on the specified template and options.

Arguments

TEMPLATE

The template to instantiate when the command is invoked. Each template might have specific options you can pass. For more information, see Template options.

If the TEMPLATE value isn't an exact match on text in the Templates or Short Name column, a substring match is performed on those two columns.

The command contains a default list of templates. Use dotnet new -l to obtain a list of the available templates. The following table shows the templates that come pre-installed with the .NET Core SDK 2.2.100. The default language for the template is shown inside the brackets.

Options

--dry-run

Displays a summary of what would happen if the given command were run if it would result in a template creation.

--force

Forces content to be generated even if it would change existing files. This is required when the output directory already contains a project.

-h|--help

Prints out help for the command. It can be invoked for the dotnet new command itself or for any template, such as dotnet new mvc --help.

-i|--install <PATH|NUGET_ID>

Installs a source or template pack from the PATH or NUGET_ID provided. If you want to install a prerelease version of a template package, you need to specify the version in the format of <package-name>::<package-version>. By default, dotnet new passes * for the version, which represents the last stable package version. See an example at the Examples section.

For information on creating custom templates, see Custom templates for dotnet new.

-l|--list

Lists templates containing the specified name. If invoked for the dotnet new command, it lists the possible templates available for the given directory. For example if the directory already contains a project, it doesn't list all project templates.

-lang|--language {C#|F#|VB}

The language of the template to create. The language accepted varies by the template (see defaults in the arguments section). Not valid for some templates.

Note

Some shells interpret # as a special character. In those cases, you need to enclose the language parameter value, such as dotnet new console -lang "F#".

-n|--name <OUTPUT_NAME>

The name for the created output. If no name is specified, the name of the current directory is used.

--nuget-source

Specifies a NuGet source to use during install.

-o|--output <OUTPUT_DIRECTORY>

Location to place the generated output. The default is the current directory.

--type

Filters templates based on available types. Predefined values are "project", "item", or "other".

-u|--uninstall <PATH|NUGET_ID>

Uninstalls a source or template pack at the PATH or NUGET_ID provided. When excluding the <PATH|NUGET_ID> value, all currently installed template packs and their associated templates are displayed.

Note

To uninstall a template using a PATH, you need to fully qualify the path. For example, C:/Users/<USER>/Documents/Templates/GarciaSoftware.ConsoleTemplate.CSharp will work, but ./GarciaSoftware.ConsoleTemplate.CSharp from the containing folder will not. Additionally, do not include a final terminating directory slash on your template path.

Create an F# console application project in the current directory:

dotnet new console -lang F#

Create a .NET Standard class library project in the specified directory (available only with .NET Core SDK 2.0 or later versions):

dotnet new classlib -lang VB -o MyLibrary

dotnet new mvc -au None

Create a new xUnit project:

dotnet new xunit

List all templates available for MVC:

dotnet new mvc -l

List all templates matching the we substring. No exact match is found, so substring matching runs against both the short name and name columns.

dotnet new we -l

Attempt to invoke the template matching ng. If a single match can't be determined, list the templates that are partial matches.

dotnet new ng

Install version 2.0 of the Single Page Application templates for ASP.NET Core (command option available for .NET Core SDK 1.1 and later versions only):

dotnet new -i Microsoft.DotNet.Web.Spa.ProjectTemplates::2.0.0

Create a global.json in the current directory setting the SDK version to 2.0.0 (available only with .NET Core SDK 2.0 or later versions):

dotnet new globaljson --sdk-version 2.0.0
