Let me start with the difference between synchronous process and asynchronous process.
As the above image depicts, we usually consider asynchronous process in case of a time taking task. Making an asynchronous call, we will execute the tedious task on a separate thread and will continue with remaining process on initial thread. Thus we will be able to execute both the tasks paralelly.
Until now we have been using a standard process of calling a function or method asynchronously.
Until .Net framework 4.0 below is the typical process of executing a method asynchronously.
I created a small sample application in Visual Studio 2013.
Before we go into more details, i would like to highlight a simple fact.
"Until .Net Framework 4.0 we call a non-asynch method asynchronously, but from .Net Framework 4.5 we have asynch methods which reduces lot of efforts in development perspective."
