## Name

dotnet restore - Restores the dependencies and tools of a project.

## Synopsis

dotnet restore [<ROOT>] [--configfile] [--disable-parallel] [--force] [--ignore-failed-sources] [--no-cache]
[--no-dependencies] [--packages] [-r|--runtime] [-s|--source] [-v|--verbosity] [--interactive]
dotnet restore [-h|--help]


## Description

The dotnet restore command uses NuGet to restore dependencies as well as project-specific tools that are specified in the project file. By default, the restoration of dependencies and tools are executed in parallel.

Note

Starting with .NET Core 2.0 SDK, you don't have to run dotnet restore because it's run implicitly by all commands that require a restore to occur, such as dotnet new, dotnet build and dotnet run. It's still a valid command in certain scenarios where doing an explicit restore makes sense, such as continuous integration builds in Azure DevOps Services or in build systems that need to explicitly control the time at which the restore occurs.

To restore the dependencies, NuGet needs the feeds where the packages are located. Feeds are usually provided via the NuGet.config configuration file. A default configuration file is provided when the CLI tools are installed. You specify additional feeds by creating your own NuGet.config file in the project directory. You also specify additional feeds per invocation at a command prompt.

For dependencies, you specify where the restored packages are placed during the restore operation using the --packages argument. If not specified, the default NuGet package cache is used, which is found in the .nuget/packages directory in the user's home directory on all operating systems. For example, /home/user1 on Linux or C:\Users\user1 on Windows.

For project-specific tooling, dotnet restore first restores the package in which the tool is packed, and then proceeds to restore the tool's dependencies as specified in its project file.

The behavior of the dotnet restore command is affected by some of the settings in the Nuget.Config file, if present. For example, setting the globalPackagesFolder in NuGet.Config places the restored NuGet packages in the specified folder. This is an alternative to specifying the --packages option on the dotnet restore command. For more information, see the NuGet.Config reference.

## Implicit dotnet restore

Starting with .NET Core 2.0, dotnet restore is run implicitly if necessary when you issue the following commands:

In most cases, you no longer need to explicitly use the dotnet restore command.

Sometimes, it might be inconvenient to run dotnet restore implicitly. For example, some automated systems, such as build systems, need to call dotnet restore explicitly to control when the restore occurs so that they can control network usage. To prevent dotnet restore from running implicitly, you can use the --no-restore flag with any of these commands to disable implicit restore.

## Arguments

ROOT

Optional path to the project file to restore.

## Options

--configfile <FILE>

The NuGet configuration file (NuGet.config) to use for the restore operation.

--disable-parallel

Disables restoring multiple projects in parallel.

--force

Forces all dependencies to be resolved even if the last restore was successful. Specifying this flag is the same as deleting the project.assets.json file.

-h|--help

Prints out a short help for the command.

--ignore-failed-sources

Only warn about failed sources if there are packages meeting the version requirement.

--no-cache

Specifies to not cache packages and HTTP requests.

--no-dependencies

When restoring a project with project-to-project (P2P) references, restores the root project and not the references.

--packages <PACKAGES_DIRECTORY>

Specifies the directory for restored packages.

-r|--runtime <RUNTIME_IDENTIFIER>

Specifies a runtime for the package restore. This is used to restore packages for runtimes not explicitly listed in the <RuntimeIdentifiers> tag in the .csproj file. For a list of Runtime Identifiers (RIDs), see the RID catalog. Provide multiple RIDs by specifying this option multiple times.

-s|--source <SOURCE>

Specifies a NuGet package source to use during the restore operation. This setting overrides all of the sources specified in the NuGet.config files. Multiple sources can be provided by specifying this option multiple times.

--verbosity <LEVEL>

Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic].

--interactive

Allows the command to stop and wait for user input or action (for example to complete authentication). Since .NET Core 2.1.400.

## Examples

Restore dependencies and tools for the project in the current directory:

dotnet restore

Restore dependencies and tools for the app1 project found in the given path:

dotnet restore ~/projects/app1/app1.csproj

Restore the dependencies and tools for the project in the current directory using the file path provided as the source:

dotnet restore -s c:\packages\mypackages

Restore the dependencies and tools for the project in the current directory using the two file paths provided as sources:

dotnet restore -s c:\packages\mypackages -s c:\packages\myotherpackages

Restore dependencies and tools for the project in the current directory and shows only minimal output:

dotnet restore --verbosity minimal
