Hmm, in what sense, or do you mean it's feasible now? I was thinking that whenever I press F5 it should instantly run. It's insane that the computer just loiters around and doesn't compile until you explicitly tells it to, when it could do incremental background compiling... especially since the editor pretty much does that anyway to provide its intellisense and stuff. The build process seems very separated from the editor. Guess it's more complicated with app that's deployed to devices though.
Live-editing I was thinking more like I could change parameters and methods and have the reflect directly in an running app. Edit-and-continue has been around for a while but doesn't work on apps ... for probably natural reasons. Eclipse seems to have stuff like that
Roslyn is a new compiler built in C# and faster. When using VS2015 (and confirmed working with asp.net 5 projects), the solution is compiled using Roslyn and completely in memory (meaning it doesnt build and then write out assemblies to disk just to read them back into memory and reset the app).
The whole cycle is way faster and there's a lot less pause time between editing a c# file, hitting save and then just hitting refresh in the browser. I'm not sure about mobile app dev but that probably has more latency due to the emulator setup.
