dotnet command

This article applies to: ✔️ .NET Core 2.1 SDK and later versions

Name

dotnet - The generic driver for the .NET CLI.

Synopsis

To get information about the available commands and the environment:

dotnet [--version] [--info] [--list-runtimes] [--list-sdks]

dotnet -h|--help

To run a command (requires SDK installation):

dotnet <COMMAND> [-d|--diagnostics] [-h|--help] [--verbosity <LEVEL>]
    [command-options] [arguments]

To run an application:

dotnet [--additionalprobingpath <PATH>] [--additional-deps <PATH>]
    [--fx-version <VERSION>]  [--roll-forward <SETTING>]
    <PATH_TO_APPLICATION> [arguments]

dotnet exec [--additionalprobingpath] [--additional-deps <PATH>]
    [--fx-version <VERSION>]  [--roll-forward <SETTING>]
    <PATH_TO_APPLICATION> [arguments]

--roll-forward is available since .NET Core 3.x. Use --roll-forward-on-no-candidate-fx for .NET Core 2.x.

Description

The dotnet command has two functions:

  • It provides commands for working with .NET projects.

    For example, dotnet build builds a project. Each command defines its own options and arguments. All commands support the --help option for printing out brief documentation about how to use the command.

  • It runs .NET applications.

    You specify the path to an application .dll file to run the application. To run the application means to find and execute the entry point, which in the case of console apps is the Main method. For example, dotnet myapp.dll runs the myapp application. See .NET application deployment to learn about deployment options.

Options

Different options are available for dotnet by itself, for running a command, and for running an application.

Options for dotnet by itself

The following options are for dotnet by itself. For example, dotnet --info. They print out information about the environment.

  • --info

    Prints out detailed information about a .NET installation and the machine environment, such as the current operating system, and commit SHA of the .NET version.

  • --version

Prints out the version of the .NET SDK used by dotnet commands. Includes the effects of any global.json

  • --list-runtimes

    Prints out a list of the installed .NET runtimes. An x86 version of the SDK lists only x86 runtimes, and an x64 version of the SDK lists only x64 runtimes.

  • --list-sdks

    Prints out a list of the installed .NET SDKs.

  • -?|-h|--help

    Prints out a list of available commands.

SDK options for running a command

The following options are for dotnet with a command. For example, dotnet build --help.

  • -d|--diagnostics

    Enables diagnostic output.

  • -v|--verbosity <LEVEL>

    Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic]. Not supported in every command. See specific command page to determine if this option is available.

  • -?|-h|--help

    Prints out documentation for a given command, such as dotnet build --help.

  • command options

    Each command defines options specific to that command. See specific command page for a list of available options.

Runtime options

The following options are available when dotnet runs an application. For example, dotnet myapp.dll --roll-forward Major.

  • --additionalprobingpath <PATH>

    Path containing probing policy and assemblies to probe.

  • --additional-deps <PATH>

    Path to an additional .deps.json file. A deps.json file contains a list of dependencies, compilation dependencies, and version information used to address assembly conflicts. For more information, see Runtime Configuration Files on GitHub.

  • --depsfile <PATH_TO_DEPSFILE>

    Path to the deps.json file. A deps.json file is a configuration file that contains information about dependencies necessary to run the application. This file is generated by the .NET SDK.

  • --runtimeconfig

    Path to a runtimeconfig.json file. A runtimeconfig.json file is a configuration file that contains run-time settings. For more information, see .NET runtime configuration settings.

  • --roll-forward <SETTING> Available starting with .NET Core SDK 3.0.

    Controls how roll forward is applied to the app. The SETTING can be one of the following values. If not specified, Minor is the default.

    • LatestPatch - Roll forward to the highest patch version. This disables minor version roll forward.
    • Minor - Roll forward to the lowest higher minor version, if requested minor version is missing. If the requested minor version is present, then the LatestPatch policy is used.
    • Major - Roll forward to lowest higher major version, and lowest minor version, if requested major version is missing. If the requested major version is present, then the Minor policy is used.
    • LatestMinor - Roll forward to highest minor version, even if requested minor version is present. Intended for component hosting scenarios.
    • LatestMajor - Roll forward to highest major and highest minor version, even if requested major is present. Intended for component hosting scenarios.
    • Disable - Don't roll forward. Only bind to specified version. This policy isn't recommended for general use because it disables the ability to roll forward to the latest patches. This value is only recommended for testing.

    With the exception of Disable, all settings will use the highest available patch version.

    Roll forward behavior can also be configured in a project file property, a runtime configuration file property, and an environment variable. For more information, see Major-version runtime roll forward.

  • --roll-forward-on-no-candidate-fx <N> Available in .NET Core 2.x SDK.

    Defines behavior when the required shared framework is not available. N can be:

    • 0 - Disable even minor version roll forward.
    • 1 - Roll forward on minor version, but not on major version. This is the default behavior.
    • 2 - Roll forward on minor and major versions.

    For more information, see Roll forward.

    Starting with .NET Core 3.0, this option is superseded by --roll-forward, and that option should be used instead.

  • --fx-version <VERSION>

    Version of the .NET runtime to use to run the application.

    This option overrides the version of the first framework reference in the application's .runtimeconfig.json file. This means it only works as expected if there's just one framework reference. If the application has more than one framework reference, using this option may cause errors.
