DESCRIPTION

       The  dotnet  workload  install  command installs one or more optional workloads.  Optional
       workloads can be installed on  top  of  the  .NET  SDK  to  provide  support  for  various
       application    types,    such    as    .NET    MAUI    and    Blazor    WebAssembly    AOT
       (https://devblogs.microsoft.com/aspnet/asp-net-core-updates-in-net-6-preview-4/#blazor-
       webassembly-ahead-of-time-aot-compilation).

       Use dotnet workload search to learn what workloads are available to install.

   When to run elevated
       For  macOS  and  Linux  SDK installations that are installed to a protected directory, the
       command needs to run elevated (use the sudo command).  On  Windows,  the  command  doesn’t
       need  to  run  elevated  even if the SDK is installed to the Program Files directory.  For
       Windows, the command uses MSI installers for that location.

   Results vary by SDK version
       The dotnet workload commands operate in the context of specific SDK versions.  Suppose you
       have  both  .NET 6.0.100 SDK and .NET 6.0.200 SDK installed.  The dotnet workload commands
       will give different results depending on which SDK  version  you  select.   This  behavior
       applies  to  major  and  minor  version and feature band differences, not to patch version
       differences.  For example, .NET SDK 6.0.101 and 6.0.102 give  the  same  results,  whereas
       6.0.100  and 6.0.200 give different results.  You can specify the SDK version by using the
       global.json file or the --sdk-version option of the dotnet workload commands.

   Advertising manifests
       The names and versions of the assets that a workload installation requires are  maintained
       in  manifests.   By  default,  the  dotnet  workload  install command downloads the latest
       available manifests before it installs a workload.  The local  copy  of  a  manifest  then
       provides the information needed to find and download the assets for a workload.

       The  dotnet  workload  list  command compares the versions of installed workloads with the
       currently available versions.  When it finds that  a  version  newer  than  the  installed
       version  is available, it advertises that fact in the command output.  These newer-version
       notifications in dotnet workload list are available starting in .NET 6.

       To enable these  notifications,  the  latest  available  versions  of  the  manifests  are
       downloaded  and stored as advertising manifests.  These downloads happen asynchronously in
       the background when any of the following commands are run.

       • dotnet build

       • dotnet pack

       • dotnet publish

       • dotnet restore

       • dotnet run

       • dotnet test

       If a command finishes before the manifest download finishes, the download is stopped.  The
       download  is  tried  again  the  next  time  one  of  these  commands is run.  You can set
       environment variables to disable these background downloads or  control  their  frequency.
       By default, they don’t happen more than once a day.

       You can prevent the dotnet workload install command from doing manifest downloads by using
       the --skip-manifest-update option.

       The dotnet workload update command also downloads advertising  manifests.   The  downloads
       are  required  to  learn  if an update is available, so there is no option to prevent them
       from running.  However, you  can  use  the  --advertising-manifests-only  option  to  skip
       workload updates and only do the manifest downloads.  This option is available starting in
       .NET 6.

ARGUMENTS

       • WORKLOAD_ID...

         The workload ID or multiple IDs to install.  Use dotnet workload search  to  learn  what
         workloads are available.

OPTIONS

       • --configfile <FILE>

         The  NuGet  configuration  file  (nuget.config) to use.  If specified, only the settings
         from this file will be used.  If not specified, the  hierarchy  of  configuration  files
         from  the  current  directory  will  be  used.   For  more information, see Common NuGet
         Configurations.

       • --disable-parallel

         Prevents restoring multiple projects in parallel.

       • -?|-h|--help

         Prints out a description of how to use the command.

       • --ignore-failed-sources

         Treats package source failures as warnings.

       • --include-previews

         Allows prerelease workload manifests.

       • --interactive

         Allows the command to stop and wait for user input or action.  For example, to  complete
         authentication.

       • --no-cache

         Prevents caching of packages and http requests.

       • --skip-manifest-update

         Skip  updating  the  workload  manifests.  The workload manifests define what assets and
         versions need to be installed for each workload.

       • -s|--source <SOURCE>

         Specifies the URI of the NuGet package source to use.  This setting overrides all of the
         sources  specified  in  the  nuget.config  files.   Multiple  sources can be provided by
         specifying this option multiple times.

       • --temp-dir <PATH>

         Specify the temporary directory used to download and extract  NuGet  packages  (must  be
         secure).

       • -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.   If  you  specify
         detailed  or  diagnostic  verbosity,  the  command  displays information about the Nuget
         packages that it downloads.

EXAMPLES

       • Install the maui workload:

                dotnet workload install maui

       • Install the maui-android and maui-ios workloads:

                dotnet workload install maui-android maui-ios
