Second .. JSON is it for ready data retrieving or for insistent data ?? .. 

 

Not trying to be rude, but I (and I'm pretty sure others) do not understand what you are saying.

 

But basically, you need to create a web service (google WCF Web Services). You then use Javascript in you web app to make ajax calls. For this, you'd probably want to use a higher level library like JQuery. Everything else, you just build on top of these fundamental components. You can configure the web service to spit out JSON and to receive JSON. For e.g, the web service sends the JSON data to the web app when the web app requests it by making a call using an endpoint "http://myservice/users". You can also have the web app send the data as JSON back to the web service through another service endpoint "http://myservice/user".

So, google JQuery ajax and WCF web services.

As Zippy said, don't do SPA unless you can get the basics correct.
