dotnet clean [<PROJECT>|<SOLUTION>] [-c|--configuration <CONFIGURATION>]

    [--nologo] [-o|--output <OUTPUT_DIRECTORY>]
    [-r|--runtime <RUNTIME_IDENTIFIER>] [-v|--verbosity <LEVEL>]

dotnet clean -h|--help

The dotnet clean command cleans the output of the previous build. It’s implemented as an MSBuild target, so the project is evaluated when the command is run. Only the outputs created during the build are cleaned. Both intermediate (obj) and final output (bin) folders are cleaned.

PROJECT | SOLUTION

The MSBuild project or solution to clean. If a project or solution file is not specified, MSBuild searches the current working directory for a file that has a file extension that ends in proj or sln, and uses that file.

• -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. This option is only required when cleaning if you specified it during build time.

• -f|--framework <FRAMEWORK>

  The framework that was specified at build time. The framework must be defined in the project file. If you specified the framework at build time, you must specify the framework when cleaning.

• -?|-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.

• --nologo

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

• -o|--output <OUTPUT_DIRECTORY>

  The directory that contains the build artifacts to clean. Specify the -f|--framework <FRAMEWORK> switch with the output directory switch if you specified the framework when the project was built.

  • .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 For more information, see Solution-level --output option no longer valid for build-related commands.

• -r|--runtime <RUNTIME_IDENTIFIER>

  Cleans the output folder of the specified runtime. This is used when a self-contained deployment was created.

• -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 normal. For more information, see <xref:Microsoft.Build.Framework.LoggerVerbosity>.

• Clean a default build of the project:

  dotnet clean

• Clean a project built using the Release configuration:

  dotnet clean --configuration Release
