ASP.Net Web API vs WCF, which one should I choose in my project
<p>I have read many articles in the web so far, about the differences between WCF and ASP.Net web API. Unfortunately I could not come up to a clear idea about what will serve my purpose. Most of the Articles I have read highlighted on the design point of view of the two web services. But I am confused what will work best for my project and why? Here is my brief description of the project.</p>

<p>I need to create a communication channel between two servers (both are written in C#). The servers will communicate using messages (certain type of commands). The messages sometimes can be only acknowledgements, and sometimes the messages may contain instructions to do some computation. For example, one message can be draw something, or send an SMS etc. And not necessarily the messages will involve any database transactions. But the messages can sometimes send large text files as payload (around 1-5 MB maxm). What I believe WCF is very will surely do this, but can I do the same with ASP.net web API. Because so far all the example I have seen for ASP.Net web api: they are good for RESTful services that manipulate some kind of DB store (GET, PUT, DELETE). But in my case I will need to expose service points that will </p>

<blockquote>
  <p>do some kind of processing such as return the value of a computation, sending and acknowledging messages, etc. </p>
</blockquote>

<p>Not just manipulating a DB-store.</p>

<p>So, what should be the best and simplest way to do so? It is needed to be mentioned that I did not find any straight forward example of achieving this using ASP.Net web API. </p>
