dotnet publish -h|--help


## Description

dotnet publish compiles the application, reads through its dependencies specified in the project file, and publishes the resulting set of files to a directory. The output includes the following assets:

• Intermediate Language (IL) code in an assembly with a dll extension.
• A .deps.json file that includes all of the dependencies of the project.
• A .runtimeconfig.json file that specifies the shared runtime that the application expects, as well as other configuration options for the runtime (for example, garbage collection type).
• The application's dependencies, which are copied from the NuGet cache into the output folder.

The dotnet publish command's output is ready for deployment to a hosting system (for example, a server, PC, Mac, laptop) for execution. It's the only officially supported way to prepare the application for deployment. Depending on the type of deployment that the project specifies, the hosting system may or may not have the .NET Core shared runtime installed on it. For more information, see Publish .NET Core apps with the .NET Core CLI.

### 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 explicitly control when the restore occurs.

For information about how to manage NuGet feeds, see the dotnet restore documentation.

### MSBuild

The dotnet publish command calls MSBuild, which invokes the Publish target. Any parameters passed to dotnet publish are passed to MSBuild. The -c and -o parameters map to MSBuild's Configuration and PublishDir properties, respectively.

The dotnet publish command accepts MSBuild options, such as -p for setting properties and -l to define a logger. For example, you can set an MSBuild property by using the format: -p:<NAME>=<VALUE>. You can also set publish-related properties by referring to a .pubxml file, for example:

dotnet publish -p:PublishProfile=FolderProfile


The preceding example uses the FolderProfile.pubxml file that is found in the <project_folder>/Properties/PublishProfiles folder. If you specify a path and file extension when setting the PublishProfile property, they are ignored. MSBuild by default looks in the Properties/PublishProfiles folder and assumes the pubxml file extension. To specify the path and filename including extension, set the PublishProfileFullPath property instead of the PublishProfile property.

## Arguments

• PROJECT|SOLUTION

The project or solution to publish.

• PROJECT is the path and filename of a C#, F#, or Visual Basic project file, or the path to a directory that contains a C#, F#, or Visual Basic project file. If the directory is not specified, it defaults to the current directory.

• SOLUTION is the path and filename of a solution file (.sln extension), or the path to a directory that contains a solution file. If the directory is not specified, it defaults to the current directory. Available since .NET Core 3.0 SDK.

## Options

• -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>

Publishes the application for the specified target framework. You must specify the target framework 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.

• --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.

• --manifest <PATH_TO_MANIFEST_FILE>

Specifies one or several target manifests to use to trim the set of packages published with the app. The manifest file is part of the output of the dotnet store command. To specify multiple manifests, add a --manifest option for each manifest.

• --no-build

Doesn't build the project before publishing. It also implicitly sets the --no-restore flag.

• --no-dependencies

Ignores project-to-project references and only restores the root project.

• --nologo

Doesn't display the startup banner or the copyright message. Available since .NET Core 3.0 SDK.

• --no-restore

Doesn't execute an implicit restore when running the command.

• -o|--output <OUTPUT_DIRECTORY>

Specifies the path for the output directory.

If not specified, it defaults to [project_file_folder]./bin/[configuration]/[framework]/publish/ for a runtime-dependent executable and cross-platform binaries. It defaults to [project_file_folder]/bin/[configuration]/[framework]/[runtime]/publish/ for a self-contained executable.

In a web project, if the output folder is in the project folder, successive dotnet publish commands result in nested output folders. For example, if the project folder is myproject, and the publish output folder is myproject/publish, and you run dotnet publish twice, the second run puts content files such as .config and .json files in myproject/publish/publish. To avoid nesting publish folders, specify a publish folder that is not directly under the project folder, or exclude the publish folder from the project. To exclude a publish folder named publishoutput, add the following element to a PropertyGroup element in the .csproj file:

<DefaultItemExcludes>\$(DefaultItemExcludes);publishoutput**</DefaultItemExcludes>

• .NET Core 3.x SDK and later

If a relative path is specified when publishing a project, the output directory generated is relative to the current working directory, not to the project file location.

If a relative path is specified when publishing a solution, all output for all projects goes into the specified folder relative to the current working directory. To make publish output go to separate folders for each project, specify a relative path by using the msbuild PublishDir property instead of the --output option. For example, dotnet publish -p:PublishDir=.\publish sends publish output for each project to a publish folder under the folder that contains the project file.

• .NET Core 2.x SDK

If a relative path is specified when publishing a project, the output directory generated is relative to the project file location, not to the current working directory.

If a relative path is specified when publishing a solution, each project's output goes into a separate folder relative to the project file location. If an absolute path is specified when publishing a solution, all publish output for all projects goes into the specified folder.

• -p:PublishReadyToRun=true

We recommend that you specify this option in a publish profile rather than on the command line. For more information, see MSBuild.

• -p:PublishSingleFile=true

Packages the app into a platform-specific single-file executable. The executable is self-extracting and contains all dependencies (including native) that are required to run the app. When the app is first run, the application is extracted to a directory based on the app name and build identifier. Startup is faster when the application is run again. The application doesn't need to extract itself a second time unless a new version is used. Available since .NET Core 3.0 SDK.

We recommend that you specify this option in a publish profile rather than on the command line. For more information, see MSBuild.

• -p:PublishTrimmed=true

Trims unused libraries to reduce the deployment size of an app when publishing a self-contained executable. For more information, see Trim self-contained deployments and executables. Available since .NET Core 3.0 SDK.

We recommend that you specify this option in a publish profile rather than on the command line. For more information, see MSBuild.

• --self-contained [true|false]

Publishes the .NET Core runtime with your application so the runtime doesn't need to be installed on the target machine. Default is true if a runtime identifier is specified and the project is an executable project (not a library project). For more information, see .NET Core application publishing and Publish .NET Core apps with the .NET Core CLI.

If this option is used without specifying true or false, the default is true. In that case, don't put the solution or project argument immediately after --self-contained, because true or false is expected in that position.

• --no-self-contained

Equivalent to --self-contained false. Available since .NET Core 3.0 SDK.

• -r|--runtime <RUNTIME_IDENTIFIER>

Publishes the application for a given runtime. For a list of Runtime Identifiers (RIDs), see the RID catalog. For more information, see .NET Core application publishing and Publish .NET Core apps with the .NET Core CLI.

• -v|--verbosity <LEVEL>

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

• --version-suffix <VERSION_SUFFIX>

Defines the version suffix to replace the asterisk (*) in the version field of the project file.

## Examples

• Create a runtime-dependent cross-platform binary for the project in the current directory:

dotnet publish


Starting with .NET Core 3.0 SDK, this example also creates a runtime-dependent executable for the current platform.

• Create a self-contained executable for the project in the current directory, for a specific runtime:

dotnet publish --runtime osx.10.11-x64


The RID must be in the project file.

• Create a runtime-dependent executable for the project in the current directory, for a specific platform:

dotnet publish --runtime osx.10.11-x64 --self-contained false


The RID must be in the project file. This example applies to .NET Core 3.0 SDK and later versions.

• Publish the project in the current directory, for a specific runtime and target framework:

dotnet publish --framework netcoreapp3.1 --runtime osx.10.11-x64

• Publish the specified project file:

dotnet publish ~/projects/app1/app1.csproj

• Publish the current application but don't restore project-to-project (P2P) references, just the root project during the restore operation:

dotnet publish --no-dependencies
