- Initialize a new .NET project:
dotnet new template_short_name
- Restore NuGet packages:
- Build and execute the .NET project in the current directory:
- Run a packaged dotnet application (only needs the runtime, the rest of the commands require the .NET Core SDK installed):
This article applies to: ✔️ .NET Core 3.1 SDK and later versions
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>] [--depsfile <PATH>] [--fx-version <VERSION>] [--roll-forward <SETTING>] [--runtimeconfig <PATH>] <PATH_TO_APPLICATION> [arguments]
dotnet command has two functions:
It provides commands for working with .NET projects.
dotnet buildbuilds a project. Each command defines its own options and arguments. All commands support the
--helpoption for printing out brief documentation about how to use the command.
It runs .NET applications.
You specify the path to an application
.dllfile 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
Mainmethod. For example,
dotnet myapp.dllruns the
myappapplication. See .NET application deployment to learn about deployment options.
Different options are available for:
- Displaying information about the environment.
- Running a command.
- Running an application.
Options for displaying environment information and available commands
The following options are available when
dotnet is used by itself, without specifying a command or an application to run. For example,
dotnet --info or
dotnet --version. They print out information about the environment.
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.
Prints out the version of the .NET SDK used by
dotnet commands, which may be affected by a global.json file. Available only when the SDK is installed.
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.
Prints out a list of the installed .NET SDKs.
Prints out a list of available commands.
Options for running a command
The following options are for
dotnet with a command. For example,
dotnet build --help or
dotnet build --verbosity diagnostic.
Enables diagnostic output.
Sets the verbosity level of the command. Allowed values are
diag[nostic]. Not supported in every command. See specific command page to determine if this option is available.
Prints out documentation for a given command. For example,
dotnet build --helpdisplays help for the
Each command defines options specific to that command. See specific command page for a list of available options.
Options for running an application
The following options are available when
dotnet runs an application. For example,
dotnet --roll-forward Major myapp.dll.
Path containing probing policy and assemblies to probe. Repeat the option to specify multiple paths.
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 (https://github.com/dotnet/sdk/blob/main/documentation/specs/runtime-configuration-file.md) on GitHub.
--roll-forward <SETTING> **
Controls how roll forward is applied to the app. The
SETTINGcan be one of the following values. If not specified,
Minoris 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.
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.jsonfile. 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.
Options for running an application with the exec command
The following options are available only when
dotnet runs an application by using the
exec command. For example,
dotnet exec --runtimeconfig myapp.runtimeconfig.json myapp.dll.
Path to a 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.
Path to a runtimeconfig.json file. A runtimeconfig.json file contains run-time settings and is typically named <applicationname>.runtimeconfig.json. For more information, see .NET runtime configuration settings.

Global, tool-path, and local tools commands
Tools are console applications that are installed from NuGet packages and are invoked from the command prompt. You can write tools yourself or install tools written by third parties. Tools are also known as global tools, tool-path tools, and local tools. For more information, see .NET tools overview.
|dotnet tool install||Installs a tool on your machine.|
|dotnet tool list||Lists all global, tool-path, or local tools currently installed on your machine.|
