Yeah, that's the standard way to write comments. It looks terrible but it's not bad to write because Visual Studio auto-generates the comment skeleton for you.
What's even worse is that Visual Studio 2015 just vomits out that the XML is malformed when I have C++ headers with Doxygen style comments in them. It detects the three slashes and tries to apply C# XML docs parsing to them and that of course fails. Meanwhile NetBeans can handle them no problem and display parsed docs in pop ups.
