Call PLSQL Procedure in ASP.NET in Visual Studio 2013

Hi all,
Please someone help me how to call PLSQL in VS 2013 using ASP.NET. I have surfed plenty of sites on Oracle connection but still I could not come up with a solution. I have to call Get_Added_Request_ID procedure and return he value of Return_ID which is the parameter of that procedure. Then the Request_ID should be parsed into another procedure- Get_Request_Details to get details on the particular Request_ID. I have created a web application in ASP.NET project and please guide me how to call each procedures and where to call which files.
