Can we Use Web Methods in Provider hosted app

I am developing a provider hosted app (Web Forms) for SharePoint Online hosted in Azure.

I am trying to implement the Web Method in the provider hosted app, but cant proceed further because all the web Methods are static. How can i get the Context in the Web Method.

If I create a Web Method without using the Context (normal function with static json object) its working fine.

Can we use Web Methods in provider Hosted Apps.?

Anyone suggest a way to move further or other approach to meet my requirement.
