From desktop (forms) application which were very popular in Windows XP users move to SOA and now completely start using web based solution hosting in a cloud . Of course such evolution is not something bad, just the opposite in my opinion because web based application are highly scalable, better secured and available from each place in the Earth where user has an Internet connection. Such a big changes in software architecture cause that also programming model has to change. As response for this need, IT companies start working for on new technologies and improving existing ones. APIs became very popular tool  in a developer hands and whole communication became much more lightweight (by switching from XML to JSON) - mainly because the emerging market of mobile devices. In a new MVC version 4 also Microsoft introduce some improvements which allow developers creating web service...

An asynchronous operations become very popular in modern programming because by using its developers can take full advantage of multicore processors and perform several operation at the same time. Multithreding exists in ASP.NET since 2.0 version but it was very sophisticated to use it. However starting from .NET 4.5, ASP.NET is fully compatible with all these great features .

AsyncPageWebsite - main ASP.NET website. Contracts - contains shared type between service and website. Picture 1. Solution projects. In my solution data is served by very simple REST web service, which is build by using  ApiController  from ASP.NET MVC. Inside this I`ve created two controllers (first return N random intege...
