I think XML is not bad. Parsing and tooling (for intellisense and stuff) should be easier to implement.

While XML is more verbose it has the advantage of being more descriptive. XML is also a better archival format. JSON is intended to be lightweight and ephemeral such as when passing small bits of data on a web service. If JSON is really a better format, then not only is Microsoft doing it wrong with .csproj and XAML but Apple is doing it wrong with Interface Builder and Google is doing it wrong with layout files. The W3C is even doing it wrong with HTML. At some point, archived files will need to be read by a human and XML is better suited for that. Just my two cents.

@whitlockjc, that hand edited YAML example almost brings me to tears of joy. If that was how project files in Visual Studio looked like, and the .sln file just disappeared (or turned into YAML as well), I'm sure my life would be lengthened by a few years. I at least know that currently, the horror of .sln, .csproj and MSBuild as a whole, is shortening my life expectancy due to heightened stress levels by a lot. I'm gnashing teeth just writing that last sentence.
