The new thing in MS web development is Razor, which at its base a templating engine.
It would be really cool if: - It would expose programmatic API (with c#5 going to Compiler-As-Service it would be a real shame if Razor would not behave the same way) - It would not enforce an over bloated base-class (like, erm, System.Web.UI.Page). I wouldn’t go as far as an Interface (since looks like they do not believe in Design By Contract over there), but a super-simple abstract base class with minimal pre-set behaviour would be nice. It is doable with still supporting Webforms/MVC integration using wrappers (like the HttpContextBase approach)
These things would allow using it as a true templating engine, which then can be embedded as a view engine for other web frameworks (like Monorail and Fubu, and more), use it for off-line email templates processing, maybe even for emitting customised setting files for automated deployment scenarios.
I need to try and explore into there and sniff around.
