I recently posted about how to integrate Git with Visual Studio. Of course Git is not the only DVCS out there.
Mercurial is another source control system similar to Git that is having more and more relevance. Google code have been supporting it for quite a while and recently Microsoft announced that Codeplex is adding it as an option for new projects. (Codeplex already supported TFS and Subversion).
I sign up for the beta and have been running a pilot project on it. Since I really like it I decided to start moving all our projects to Kiln and ditch Subversion. The piece that I was missing was a good integration into VS for the rest of my team.
A few day ago I found Mercurial VSS an integration package for Mercurial into VS.
The installation is very simple, just select the version of VS you want to install against (version 1.0.7 released today integrates without problems with both VS 2008 and 2010 RC).
After installed go to Tools ??"> Options and make sure you select display all options (only in VS 2008).
Select the Source Control option and in the Plug-in Selection option change it to Mercurial.
After open a project (even one that is already under source control) you will need to select the Add to source control option from the contextual menu inside the Solution explorer.
After added you will se a tilde besides each project.
This are the options available from the contextual menu.
And a few screen captures of the different options.
With the support from Codeplex and Google code to Mercurial and the tight integration that this plug in presents I see no reason why people will not use it as the DVCS of choice for .net open source projects hosted on those sites.
