r.net and rdotnet refer to the same library and should be merged. Each has slightly fewer than 100 questions, and a fair few of these carry both tags.
rdotnet has slightly more questions but I don’t know whether there’s a “canonical” tag naming style that makes one more appropriate than the other. The actual library itself uses both stylings (“R.NET” and “rdotnet”).
I agree this is a good idea. With the help of the magical unicorn powers bestowed upon me, this merge and synonym mapping is now live on a Stack Overflow near you:
I also wasn't sure which variant of the name to pick as the "master" tag. I arbitrarily chose r.net because that looks nicer and more readable to me. If someone has a compelling reason that I should reconsider, please let me know.
