CodeFormatter is a tool that uses Roslyn to automatically rewrite the source to follow our coding styles, which are documented here.

FORK NOTE: This fork was created to customize the default behavior of the codeformatter:

• use tabs instead of spaces for code indenting
• no Microsoft-copyright by default (can be activated with param /withcopyright)

In order to build or run this tool you will need to have Microsoft Build Tools 2015 installed. This comes as a part of Visual Studio 2015.

Download binaries from GitHub Releases

In order get the usage, simply invoke the tool with no arguments:

$ .\CodeFormatter.exe
CodeFormatter <project or solution> [<rule types>] [/file:<filename>] [/withcopyright] [/c:<config1,config2> [/copyright:file]
    <rule types> - Rule types to use in addition to the default ones.
                   Use ConvertTests to convert MSTest tests to xUnit.
    <filename>   - Only apply changes to files with specified name.
    <configs>    - Additional preprocessor configurations the formatter
                   should run under.
    <copyright>  - Specifies file containing copyright header.
