I am currently using Mercurial via Tortoise Hg for some of my side projects. I was wondering if there is tighter integration of Mercurial with Visual Studio 2010 via a plugin or some similar mechanism. What I'm thinking about is very similar to the git extensions which provide a plugin for VS. The plan is to eventually host the projects on Codeplex which supports Mercurial.
sure there is visualHG which works for 2005 to 2013 including 2010 .
another alternative (useful if you are in an environment where you don't have control over what is installed) is to use VS's external tools menus/buttons to launch tortoiseHg windows via thg
