ASP.NET MVC 4 Custom Fields

The project is an ASP.NET MVC 4 project with jQuery. The backend consists of an SLQ Server 2008 R2. All data access is done through Entity Framework Code First. This project is an extension to an already existing site for event/category management + participant registration. The event organizer now want to add custom fields to the list of standard properties (name, description...). An example of such a custom field could be that the event organizer now required the participant to enter his shoe size. This project should therefore deliver the tables/models/views to allow the creators to add these custom fields to an event/category. Another part of this project to develop is the extension of the participant registration form for a category. This extension partial view is based on the list of custom fields defined for the event & category. So expected deliverables: SQL script for table certain + necessary models + Views (administrative view + participant view) Details will be provided.
