Usage:
  dotnet-format [options] [<workspace>]

Arguments:
  <workspace>  A path to a solution file, a project file, or a folder containing a solution or project file. If a path is not specified then the current directory is used. [default: ]

Options:
  --no-restore                                                             Doesn't execute an implicit restore before formatting.
  -f, --folder                                                             Whether to treat the `<workspace>` argument as a simple folder of files.
  -w, --fix-whitespace                                                     Run whitespace formatting. Run by default when not applying fixes.
  -s, --fix-style <error|info|warn>                                        Run code style analyzers and apply fixes.
