Starting with the .NET 6 Preview 7, which is available now, dotnet format is a built-in SDK command. As part of this move the options have changed a bit.

Invoking the SDKs dotnet format command will fix whitespace, code style, and analyzer issues by default.

There are also 3 subcommands to target specific scenarios:

• dotnet format whitespace: fixes whitespace
• dotnet format style: runs code style analyzers
• dotnet format analyzers: runs third party analyzers

Common options for all commands

• --no-restore: Doesn't execute an implicit restore before formatting.
• --include-generated: Format files generated by the SDK
• --include: A list of relative file or folder paths to include in formatting. All files are formatted if empty.
• --exclude: A list of relative file or folder paths to exclude from formatting.
• --verbosity: Set the verbosity level. Allowed values are q[uiet], m[inimal], n[ormal], d[etailed], and diag[nostic]
• --report: Accepts a file path, which if provided, will produce a json report in the given directory.
• --binarylog: Log all project or solution load information to a binary log file.
• --verify-no-changes: Verify no formatting changes would be performed. Terminates with a non-zero exit code if any files would have been formatted.
