We are about to develop an enterpirse WebApplication for online ticket reservation, scheduling, managing suppliers, accepting online customer registeration & reservation, online payment and opening acounts for our agents (in different countries) to handel there tansactions in the system.
1. And now VS2012 officialy released .. I'm asking about its stability since its new to the commerical area, is it safe to start with it or shall we give it more time in the market & start now the project in VS2010?
2. For such WebApp, what technologies and tools suggested to be used in terms of speeding up the development time, avoiding SQL injections, stability .. etc, (HTML5, MVC, linq, entity framework .. others )
My experience in developping Enterprise web apps with Microsoft Visual studio lineup, is that its suitable for scalable mission critical web apps. My advice would be to thouroughly test the MVC concept. I dont know the size/experience of your development team, but TEAM FOUNDATION development is guaranteed. The programminglanguage (c++, c#, etc) is ofcourse an aspect not to be overlooked!
First make a solid functional and architectural design eg. 1. how many foreign offices, cultural aspects, how many customers, how many transactions etc.
Make a good functional design, as this is imperative to have a good start!
So you will gain better insight of your userinterface, your middleware and backend.
There are a few Codegenerators as well suitable which can be integrated tp VS2012 (e.g.CodeOnTime)
As a start i would suggest to make a small prototype system based on your needs.
