NAME
dotnet run - Runs source code without any explicit compile or launch commands.
SYNOPSIS
dotnet run [-a|--arch <ARCHITECTURE>] [-c|--configuration <CONFIGURATION>]
[-f|--framework <FRAMEWORK>] [--force] [--interactive]
[--launch-profile <NAME>] [--no-build]
[--no-dependencies] [--no-launch-profile] [--no-restore]
[--os <OS>] [--project <PATH>] [-r|--runtime <RUNTIME_IDENTIFIER>]
[-v|--verbosity <LEVEL>] [[--] [application arguments]]
dotnet run -h|--help
DESCRIPTION
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, such as that the project must be
restored first, 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/net‐
coreapp2.1. 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 out‐
side of the shared runtime from the NuGet cache. Because it uses cached dependencies, it’s not recom‐
mended to use dotnet run to run applications in production. Instead, create a deployment using the dot‐
net publish command and deploy the published output.
Implicit restore
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 explicit‐
ly 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.
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.
OPTIONS
• --
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 to win-x86. If you use this option, don’t use the -r|--runtime op‐
tion. 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 de‐
fined in the launchSettings.json file and are typically called Development, Staging, and Production.
For more information, see Working with multiple environments.
• --no-build
Doesn’t build the project before running. It also implicit 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 Identi‐
fier (RID), where the provided value is combined with the default RID. For example, on a win-x64 ma‐
chine, specifying --os os sets the RID to os-x64. If you use this option, don’t use the -r|--runtime
option. Available since .NET 6 Preview 7.
• --project <PATH>
Specifies the path of the project file to run (folder name or full path). If not specified, it de‐
faults to the current directory.
The -p abbreviation for --project is deprecated starting in .NET 6 Preview 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 repeat‐
ing 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. -r short option available since .NET Core 3.0 SDK.
• -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.Frame‐
work.LoggerVerbosity>.
EXAMPLES
• 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 applica‐
tion, 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
