I know that I think that it is pretty crappy that XP is not supported. But you are right, seems to be the MS is shooting itself in the foot these days. Windows 8 apparently sucks as a desktop OS. Of coures MS almost always seems to get OS's wrong the first time. T
Microsoft no longer supports XP. They are trying to get people away from it, and newer features would be hampered by working in the limitations. A lot of people have 64 bit machines now, so it doesn't make sense to stick with XP.

Of course, it just reduces the number of applications that will use 4.5. In my organization there are still xp machines, and there is lots of money in the organization. That does not include the number of XP personal PCs that are in use and will be in use for many years. There will be a lot of people that will resist 4.5 because of this stupidity. There is not a good reason to move up to Win7. Of course they want people to buy win8, which is not a good enough OS of desktop for people to buy (people complain about adapting to Win. Why upgrade when OS works fine. Which means that framework 4.5 will not be readily adopted by many organizations. Microsoft is just pissing people off. Not good for Microsoft. I am definately pissed at this overisght.
Windows XP is over 10 years old. I personally feel Microsoft has done a great job of supporting Windows XP as it is now 3 OSes behind current version. Mainstream support ended in 2009 yet they have still released major updates for it. Windows XP is now in extended support which just covers hotfixes basically.
With regard to orgs not adopting framework 4.5 due to it not supporting Windows XP, I've actually seen that as a pretty good pressure point on management to finally upgrade those machines to more current OSes.

then I wrote a code in a (Silverlight enabled WCF) to read all the data in cDetails table
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public List<cDetail > Get_Candidates()
ttEntities1 db = new ttEntities1();
// Add more operations here and mark them with [OperationContract]
when I tried to consume this service in Silverlight client I got the error (the remote server returned an error Not Found),
I tried to consume it in widows application client and in windows 8 client I got another error
An error occurred while receiving the HTTP response to http://localhost:1552/Candidates_Service.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
the strange thing is when I remove the parent table and work without relations everything work as expected.
and the same code is working when I tried to use it to bind data directly on a web form (without using the service).
also after a lot of google search I found some articles speaking that I have to make the LasyLoadingEnabled = false
and another said it is the data size Issue so a made the LasyLoadingEnabled as false and changed the size to 2GB (there are only 4 records in the table) and the result was the same.
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.
