All that functionality is availble as a stand-alone app whoes name I can't think of at the moment. It is better than doing SQL in emacs and it is better than MySQL's query browser, But I wouldn't say that would be a the showcase item for me. Although I do love the fact it does integrate some great features like this in to the IDE.
The whole process is incredebly refined. Triple comment code meta data is fucking fantastic. (you enter 3 comment delimiters in a row immediatly preceding a procedure signature and it automatically creates the XML to enter in detailed comment metadata.)
It always stays ahead of the curve on code completion with intellesense.
VB.Net's constant precompliation makes finding many errors in code trivial as they are displaye dbefore compile. (Strangley C# doesn't do this though).
The built in web server makes quick tests trivial as well.
Then there is all the team, testing and other shit built in.
