Client Crud

I need add/Update/delete/list Client. Option to export to excel, PDF, csv Code will be using 4 different Projects 1. ASP.NET MVC Razor 4 or 5 for Presentation Layer. Ajax Calls. Validation will be in Model only. 2. MVC Web API using SQLCommand classes. This will return Json data. 3. Business Logic Layer. This will have function . Each function will call WebAPI url. 4. Object Model. All classes will be defined in this project. You will return Model from Business Logic layer which doing deserialization of Json data. Multiple users will access this page. So it should not hang the application. Use [login to view URL]
