Need an API controller ASP.net which will be used for mobile devices as well as on main page as charts require json. I'm total out of my element with this so, I may be stating some obvious points, sorry.
We currently have a VB file that contains functions and Subs for connection to the stored procedure in the database.
All data is based on the users information which is used to get the AccountID, then the SP can be called.
For the mobile part both directions will be required as they will be pushing data for calculations
