Like all Microsoft development tools ASP.NET is huge and designed to do just about everything for you - provided you are happy to build web sites as they were envisaged by the tool designers. There lies the problem - the folks that built the tool set were not web site architects but tool set architects. Thus its abstractions leak as soon as you start to head off in your own design directions. I regularly use ASP.NET to build complex Ajax powered interactive web sites BUT (and this is important) I take from the tool set what helps with my sites and ignore the rest. I write (just about) all my own client side scripts and use the normal techniques for building parts of pages on the fly from JSON objects but server side the ASP.NET framework is near perfect and provides just what I need to build my apps.
