dotnet build -h|--help


The dotnet build command builds the project and its dependencies into a set of binaries. The binaries include the project's code in Intermediate Language (IL) files with a .dll extension. Depending on the project type and settings, other files may be included, such as:

  • An executable that can be used to run the application, if the project type is an executable targeting .NET Core 3.0 or later.
  • Symbol files used for debugging with a .pdb extension.
  • A .deps.json file, which lists the dependencies of the application or library.
  • A .runtimeconfig.json file, which specifies the shared runtime and its version for an application.
  • Other libraries that the project depends on (via project references or NuGet package references).

For executable projects targeting versions earlier than .NET Core 3.0, library dependencies from NuGet are typically NOT copied to the output folder. They're resolved from the NuGet global packages folder at run time. With that in mind, the product of dotnet build isn't ready to be transferred to another machine to run. To create a version of the application that can be deployed, you need to publish it (for example, with the dotnet publish command). For more information, see .NET Application Deployment.

For executable projects targeting .NET Core 3.0 and later, library dependencies are copied to the output folder. This means that if there isn't any other publish-specific logic (such as Web projects have), the build output should be deployable.

Implicit restore

Building requires the project.assets.json file, which lists the dependencies of your application. The file is created when dotnet restore is executed. Without the assets file in place, the tooling can't resolve reference assemblies, which results in errors.

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.

Executable or library output

Whether the project is executable or not is determined by the <OutputType> property in the project file. The following example shows a project that produces executable code:


To produce a library, omit the <OutputType> property or change its value to Library. The IL DLL for a library doesn't contain entry points and can't be executed.


dotnet build uses MSBuild to build the project, so it supports both parallel and incremental builds. For more information, see Incremental Builds.

In addition to its options, the dotnet build command accepts MSBuild options, such as -p for setting properties or -l to define a logger. For more information about these options, see the MSBuild Command-Line Reference. Or you can also use the dotnet msbuild command.


When dotnet build is run automatically by dotnet run, arguments like -property:property=value aren't respected.

Running dotnet build is equivalent to running dotnet msbuild -restore; however, the default verbosity of the output is different.

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.



The project or solution file to build. If a project or solution file isn't specified, MSBuild searches the current working directory for a file that has a file extension that ends in either proj or sln and uses that file.


  • -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 option. Available since .NET 6 Preview 7.

  • --artifacts-path <ARTIFACTS_DIR>

    All build output files from the executed command will go in subfolders under the specified path, separated by project. For more information see Artifacts Output Layout. Available since .NET 8 SDK.

  • -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.

  • --disable-build-servers

    Forces the command to ignore any persistent build servers. This option provides a consistent way to disable all use of build caching, which forces a build from scratch. A build that doesn't rely on caches is useful when the caches might be corrupted or incorrect for some reason. Available since .NET 7 SDK.

  • -f|--framework <FRAMEWORK>

    Compiles for a specific framework. The framework must be defined in the project file. Examples: net7.0, net462.

  • --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.

  • --no-dependencies

    Ignores project-to-project (P2P) references and only builds the specified root project.

  • --no-incremental

    Marks the build as unsafe for incremental build. This flag turns off incremental compilation and forces a clean rebuild of the project's dependency graph.

  • --no-restore

    Doesn't execute an implicit restore during build.

  • --nologo

    Doesn't display the startup banner or the copyright message.

  • --no-self-contained

    Publishes the application as a framework dependent application. A compatible .NET runtime must be installed on the target machine to run the application. Available since .NET 6 SDK.

  • -o|--output <OUTPUT_DIRECTORY>

    Directory in which to place the built binaries. If not specified, the default path is ./bin/<configuration>/<framework>/. For projects with multiple target frameworks (via the TargetFrameworks property), you also need to define --framework when you specify this option.

    • .NET 7.0.200 SDK and later

      If you specify the --output option when running this command on a solution, the CLI will emit a warning (an error in 7.0.200) due to the unclear semantics of the output path. The --output option is disallowed because all outputs of all built projects would be copied into the specified directory, which isn't compatible with multi-targeted projects, as well as projects that have different versions of direct and transitive dependencies. For more information, see Solution-level --output option no longer valid for build-related commands.

  • --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 to linux-x64. If you use this option, don't use the -r|--runtime option. Available since .NET 6.

  • -p|--property:<PROPERTYNAME>=<VALUE>

    Sets one or more MSBuild properties. Specify multiple properties delimited by semicolons or by repeating the option:

    --property:<NAME1>=<VALUE1> --property:<NAME2>=<VALUE2>
  • -r|--runtime <RUNTIME_IDENTIFIER>

    Specifies the target runtime. For a list of Runtime Identifiers (RIDs), see the RID catalog. If you use this option with .NET 6 SDK, use --self-contained or --no-self-contained also. If not specified, the default is to build for the current OS and architecture.

  • --self-contained [true|false]

    Publishes the .NET runtime with the application so the runtime doesn't need to be installed on the target machine. The default is true if a runtime identifier is specified. Available since .NET 6.

  • --source <SOURCE>

    The URI of the NuGet package source to use during the restore operation.

  • --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], and diag[nostic]. The default is minimal. By default, MSBuild displays warnings and errors at all verbosity levels. To exclude warnings, use /property:WarningLevel=0. For more information, see LoggerVerbosity and WarningLevel.

  • --use-current-runtime, --ucr [true|false]

    Sets the RuntimeIdentifier to a platform portable RuntimeIdentifier based on the one of your machine. This happens implicitly with properties that require a RuntimeIdentifier, such as SelfContained, PublishAot, PublishSelfContained, PublishSingleFile, and PublishReadyToRun. If the property is set to false, that implicit resolution will no longer occur.

  • --version-suffix <VERSION_SUFFIX>

    Sets the value of the $(VersionSuffix) property to use when building the project. This only works if the $(Version) property isn't set. Then, $(Version) is set to the $(VersionPrefix) combined with the $(VersionSuffix), separated by a dash.
