The latest version of CR_Documentor, 220.127.116.11, has been released.
This version is an update to .NET 4 in preparation for a VSIX-based installer (think Visual Studio Gallery) so it will only support Visual Studio 2010.
It also resolves a small issue where some interfaces changed in DXCore 11.2.8 and the plugin was throwing exceptions. You will need the latest CodeRush/Refactor/DXCore (11.2.8) or things may not work. (I admittedly haven't tried it on earlier versions.)
Free, as always, so go get it! And watch for the VSIX installer, coming soon!
