I tend to use Regionerate quite extensively for reorganizing my code files. My only problem is I can't get it registered with VS2012. I've abandoned VS2010 fully in favour of VS2012 and it's galling to have to flip back just to run a macro to reorganize code files. I've never tried writing a VS addin before so I'm not at all familiar with the object model or how to register - seems the old addins are more complicated to install than the VS2010 extensions! I've also looked through the WIX setup XML and tried replicating the registry keys to no avail.
Does anyone know how to either register Regionerate with VS2012, or is there an alternative (free and which is maintained!) extension that provides the same functionality?
