Grab it from inside of Visual Studio's Extension Manager, or via the Extension Gallery link

Or use the Chocolatey installation



Thanks to Sam Harwell @sharwell for all the improvements

Thanks to Rick Sladkey @ricksladkey for the fixes

Thanks to @Iristyle for the chocolatey package

Let's take a quick look at the Solution (and of course, use it, to play with the extension itself... :)


On a related note, I love NuGet. I cloned the repo, fired off a build and with the power of NuGet, in just seconds I had a successful build.


You remember the time before NuGet? When we had to hunt down and install all of a Project's dependences? Or bloat our repo's with all the bin's? It used to make my life, writing this blog "interesting".

A project like this, with this many dependacneys would have likely been a major pain to get to compile.


Today? Clone, build, complete. Woot!

So anyway... I install the Extension and used it on its project.


It was quick, easy and nicely intuitive. I love the ability to roll back the specific change. Kind of like an uber-smart undo (Not that we ever need something like that... um... yeah... )

If you're using any modern Visual Studio version, 2010-"14", using it the Git, you owe it to your self to check out this extension...

    Great post, great tool but I can't install GitDiffMargin on my Visual Studio 2012 Express :< When we can expect release for VS Express?

  • User profile image

    @TrustMe00 I wouldn't count on that happening. The Express editions are very locked down and restricted when it comes to third party extensions, whereas Visual Studio versions you pay for are not. I've seen it where it's sometimes hard for even internal to Microsoft extensions to be available in Express versions.

    @TrustME00 It is not possible to have it in Express due to Microsoft restrictions
