dotnet run -h|--help
The dotnet run
command provides a convenient option to run your application from the source code with one command. It's useful for fast iterative development from the command line. The command depends on the dotnet build
command to build the code. Any requirements for the build apply to dotnet run
as well.
Note
dotnet run
doesn't respect arguments like /property:property=value
, which are respected by dotnet build
.
Output files are written into the default location, which is bin/<configuration>/<target>
. For example if you have a netcoreapp2.1
application and you run dotnet run
, the output is placed in bin/Debug/netcoreapp2.1
. Files are overwritten as needed. Temporary files are placed in the obj
directory.
If the project specifies multiple frameworks, executing dotnet run
results in an error unless the -f|--framework <FRAMEWORK>
option is used to specify the framework.
The dotnet run
command is used in the context of projects, not built assemblies. If you're trying to run a framework-dependent application DLL instead, you must use dotnet without a command. For example, to run myapp.dll
, use:
dotnet myapp.dll
For more information on the dotnet
driver, see the .NET Command Line Tools (CLI) topic.
To run the application, the dotnet run
command resolves the dependencies of the application that are outside of the shared runtime from the NuGet cache. Because it uses cached dependencies, it's not recommended to use dotnet run
to run applications in production. Instead, create a deployment using the dotnet publish
command and deploy the published output.
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
, dotnet run
, dotnet test
, dotnet publish
, and dotnet pack
. To disable implicit restore, use the --no-restore
option.
The dotnet restore
command is still useful in certain scenarios where explicitly restoring makes sense, such as continuous integration builds in Azure DevOps Services or in build systems that need to explicitly control when the restore occurs.
For information about how to manage NuGet feeds, see the dotnet restore
documentation.
This command supports the dotnet restore
options when passed in the long form (for example, --source
). Short form options, such as -s
, are not supported.
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.
--
Delimits arguments to
dotnet run
from arguments for the application being run. All arguments after this delimiter are passed to the application run.
-a|--arch <ARCHITECTURE>
Specifies the target architecture. This is a shorthand syntax for setting the Runtime Identifier (RID), where the provided value is combined with the default RID. For example, on a
win-x64
machine, specifying--arch x86
sets the RID towin-x86
. If you use this option, don't use the-r|--runtime
option. Available since .NET 6 Preview 7.
-c|--configuration <CONFIGURATION>
Defines the build configuration. The default for most projects is
Debug
, but you can override the build configuration settings in your project.
-f|--framework <FRAMEWORK>
Builds and runs the app using the specified framework. The framework must be specified in the project file.
--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 description of how to use the command.
--interactive
Allows the command to stop and wait for user input or action. For example, to complete authentication. Available since .NET Core 3.0 SDK.
--launch-profile <NAME>
The name of the launch profile (if any) to use when launching the application. Launch profiles are defined in the launchSettings.json file and are typically called
Development
,Staging
, andProduction
. For more information, see Working with multiple environments.--no-build
Doesn't build the project before running. It also implicitly sets the
--no-restore
flag.--no-dependencies
When restoring a project with project-to-project (P2P) references, restores the root project and not the references.
--no-launch-profile
Doesn't try to use launchSettings.json to configure the application.
--no-restore
Doesn't execute an implicit restore when running the command.
--os <OS>
Specifies the target operating system (OS). This is a shorthand syntax for setting the Runtime Identifier (RID), where the provided value is combined with the default RID. For example, on a
win-x64
machine, specifying--os linux
sets the RID tolinux-x64
. If you use this option, don't use the-r|--runtime
option. Available since .NET 6.
--project <PATH>
Specifies the path of the project file to run (folder name or full path). If not specified, it defaults to the current directory.
The
-p
abbreviation for--project
is deprecated starting in .NET 6 SDK. For a limited time starting in .NET 6 RC1 SDK,-p
can still be used for--project
despite the deprecation warning. If the argument provided for the option doesn't contain=
, the command accepts-p
as short for--project
. Otherwise, the command assumes that-p
is short for--property
. This flexible use of-p
for--project
will be phased out in .NET 7.--property:<NAME>=<VALUE>
Sets one or more MSBuild properties. Specify multiple properties delimited by semicolons or by repeating the option:
--property:<NAME1>=<VALUE1>;<NAME2>=<VALUE2> --property:<NAME1>=<VALUE1> --property:<NAME2>=<VALUE2>
The short form
-p
can be used for--property
. If the argument provided for the option contains=
,-p
is accepted as short for--property
. Otherwise, the command assumes that-p
is short for--project
.To pass
--property
to the application rather than set an MSBuild property, provide the option after the--
syntax separator, for example:dotnet run -- --property name=value
-r|--runtime <RUNTIME_IDENTIFIER>
Specifies the target runtime to restore packages for. For a list of Runtime Identifiers (RIDs), see the RID catalog.
--tl:[auto|on|off]
Specifies whether the terminal logger should be used for the build output. The default is
auto
, which first verifies the environment before enabling terminal logging. The environment check verifies that the terminal is capable of using modern output features and isn't using a redirected standard output before enabling the new logger.on
skips the environment check and enables terminal logging.off
skips the environment check and uses the default console logger.The terminal logger shows you the restore phase followed by the build phase. During each phase, the currently building projects appear at the bottom of the terminal. Each project that's building outputs both the MSBuild target currently being built and the amount of time spent on that target. You can search this information to learn more about the build. When a project is finished building, a single "build completed" section is written that captures:
- The name of the built project.
- The target framework (if multi-targeted).
- The status of that build.
- The primary output of that build (which is hyperlinked).
- Any diagnostics generated for that project.
This option is available starting in .NET 8.
-v|--verbosity <LEVEL>
Sets the verbosity level of the command. Allowed values are
q[uiet]
,m[inimal]
,n[ormal]
,d[etailed]
, anddiag[nostic]
. The default isminimal
. For more information, see LoggerVerbosity.
Run the project in the current directory:
dotnet run
Run the specified project:
dotnet run --project ./projects/proj1/proj1.csproj
Run the project in the current directory, specifying Release configuration:
dotnet run --property:Configuration=Release
Run the project in the current directory (the
--help
argument in this example is passed to the application, since the blank--
option is used):dotnet run --configuration Release -- --help
Restore dependencies and tools for the project in the current directory only showing minimal output and then run the project:
dotnet run --verbosity m
