Over the past two moths I have been exploring .net 3.5. I have discovered that developing in Microsofts world there are lots of tools and built in libraries to make developing much faster. Coming from the past three years of lots of open-source, PHP/Linux development Microsoft makes many development chores a lot easier. And you can get into the plumbing and mess around with stuff also to tweak things they way you want to. I am getting more excited about the possiblities all the time.
It is cool too that it is so easy to integrate open-source stuff like jQuery into ASP.net. All of that stuff just makes developing easier and faster. It is cool too that jQuery has build stuff to make intellisense work with Visual Studio.
