  • Flexible: Convert a small selection, or a whole solution in one go, in either direction.
  • Accurate: Full project context (through Roslyn) is used to get the most accurate conversion.
  • Safe: Conversion runs entirely locally - your code doesn't leave your machine.
  • Completely free and open source GitHub project.
  • Integrated: Uses the Output window to show conversion progress / summary.
  • Actively developed: User feedback helps us continuously strive for a more accurate conversion.

Let us know what needs improving. If you want to get involved in writing the code yourself, even better! We've already had code contributions from several first time GitHub contributors, so don't be shy! See for more info.

Other ways to use the converter


This was previously part of Refactoring Essentials. However, because of the way analyzers are tied to Visual Studio and Roslyn versions made it super-hard to co-evolve the code converter bits. That is why we teased the converters out and they are now a self-contained entity.
