Name

dotnet run - Runs source code without any explicit compile or launch commands.

Synopsis

dotnet run [-c|--configuration] [-f|--framework] [--force] [--launch-profile] [--no-build] [--no-dependencies]
    [--no-launch-profile] [--no-restore] [-p|--project] [--runtime] [-v|--verbosity] [[--] [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.

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 Core 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.

Note

Starting with .NET Core 2.0, you don't have to run dotnet restore because it's run implicitly by all commands, such as dotnet build and dotnet run, that require a restore to occur. It's still a valid command in certain scenarios where doing an explicit restore makes sense, such as continuous integration builds in Azure DevOps Services or in build systems that need to explicitly control the time at which the restore occurs.

This command also supports the dotnet restore options when passed in the long form (for example, --source). Short form options, such as -s, are not supported.

Options

--

Delimits arguments to dotnet run from arguments for the application being run. All arguments after this delimiter are passed to the application run.

-c|--configuration {Debug|Release}

Defines the build configuration. The default value is Debug.

-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 short help for the command.

--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, 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.

-p|--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.

--runtime <RUNTIME_IDENTIFIER>

Specifies the target runtime to restore packages for. For a list of Runtime Identifiers (RIDs), see the RID catalog.

-v|--verbosity <LEVEL>

Sets the verbosity level of the command. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic].

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 (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: (.NET Core SDK 2.0 and later versions):

dotnet run --verbosity m
