During my two days NAV ALM using TFS training I got the question how I did configure my Visual Studio client to work with Araxis instead of the built-in compare tool. I easily could show them how it was configured.
Nevertheless I had to admit I didn’t think up this myself. So I googled for TFS how to set Araxis as compare tool and directly did hit the blog post that helped me so much ever since I am using TFS:
He does not only give settings for Araxis but for many more compare tools including Beyond Compare. And … also settings to use external tools for merging. But I never have used that as the internal tool has an important advantage over Araxis Merge: it’s much easier to select/include code into the result from either source or destination.
