dotnet-restore - Man Page

Restores the dependencies and tools of a project.

Examples (TL;DR)

Restore dependencies for a .NET project or solution in the current directory: dotnet restore
Restore dependencies for a .NET project or solution in a specific location: dotnet restore path/to/project_or_solution
Restore dependencies without caching the HTTP requests: dotnet restore --no-cache
Force all dependencies to be resolved even if the last restore was successful: dotnet restore --force
Restore dependencies using package source failures as warnings: dotnet restore --ignore-failed-sources
Restore dependencies with a specific verbosity level: dotnet restore --verbosity quiet|minimal|normal|detailed|diagnostic

dotnet restore -h|--help

The dotnet restore command uses NuGet to restore dependencies as well as project-specific tools that are specified in the project file. In most cases, you don’t need to explicitly use the dotnet restore command, since a NuGet restore is run implicitly if necessary when you run the following commands:

dotnet new
dotnet build
dotnet build-server
dotnet run
dotnet test
dotnet publish
dotnet pack

Sometimes, it might be inconvenient to run the implicit NuGet restore with these commands. 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 the implicit NuGet restore, you can use the --no-restore flag with any of these commands to disable implicit restore.

Signed package verification during restore operations requires a certificate root store that is valid for both code signing and timestamping. See NuGet signed package verification for details.

Specify feeds

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 .NET SDK is installed. To specify additional feeds, do one of the following:

Create your own nuget.config file in the project directory. For more information, see Common NuGet configurations and nuget.config differences later in this article.
Use dotnet nuget commands such as dotnet nuget add source.

You can override the nuget.config feeds with the -s option.

For information about how to use authenticated feeds, see Consuming packages from authenticated feeds.

Global packages folder

For dependencies, you can 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: on Windows.

Project-specific tooling

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.

nuget.config differences

The behavior of the dotnet restore command is affected by 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.

There are three specific settings that dotnet restore ignores:

bindingRedirects
Binding redirects don’t work with <PackageReference> elements and .NET only supports <PackageReference> elements for NuGet packages.
solution
This setting is Visual Studio specific and doesn’t apply to .NET. .NET doesn’t use a packages.config file and instead uses <PackageReference> elements for NuGet packages.
trustedSigners
Support for cross-platform package signature verification was added in the .NET 5.0.100 SDK.

Workload manifest downloads

When you run this command, it initiates an asynchronous background download of advertising manifests for workloads. If the download is still running when this command finishes, the download is stopped. For more information, see Advertising manifests.

Arguments

ROOT
Optional path to the project file to restore.

Options

--configfile <FILE>
The NuGet configuration file (nuget.config) to use. If specified, only the settings from this file will be used. If not specified, the hierarchy of configuration files from the current directory will be used. For more information, see Common NuGet Configurations.
--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.
--force-evaluate
Forces restore to reevaluate all dependencies even if a lock file already exists.
-?|-h|--help
Prints out a description of how to use the command.
--ignore-failed-sources
Only warn about failed sources if there are packages meeting the version requirement.
--interactive
Allows the command to stop and wait for user input or action. For example, to complete authentication.
--lock-file-path <LOCK_FILE_PATH>
Output location where project lock file is written. By default, this is PROJECT_ROOT.lock.json.
--locked-mode
Don’t allow updating project lock file.
--no-cache
Specifies to not cache 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.
-s|--source <SOURCE>
Specifies the URI of the 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.
--use-lock-file
Enables project lock file to be generated and used with restore.
-v|--verbosity <LEVEL>
Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic]. The default is minimal. For more information, see <xref:Microsoft.Build.Framework.LoggerVerbosity>.

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 showing detailed output:
```
dotnet restore --verbosity detailed
```
