## Overview

MarketPlace is an ASP.NET MVC marketplace for browsing and managing product listings, with account management, user profiles and reviews, chat-related data, and administrator tools. The visible browsing workflow runs from a visitor through Home or product search to product and category repositories backed by the application database. Signed-in users can manage profiles and post reviews; account and admin actions use ASP.NET Identity. Chat and notification modules are present in the tree, but their controller wiring could not be established from the sampled source; the README is empty.

Main entry points: [`MarketPlace/Data/RepositoryWrapper.cs`](https://github.com/khutyu/marketplace/blob/master/MarketPlace/Data/RepositoryWrapper.cs) (Repository wrapper), [`MarketPlace/Data/RepositoryBase.cs`](https://github.com/khutyu/marketplace/blob/master/MarketPlace/Data/RepositoryBase.cs) (Repository base), [`MarketPlace/Data/Services/UserServices.cs`](https://github.com/khutyu/marketplace/blob/master/MarketPlace/Data/Services/UserServices.cs) (User services), [`MarketPlace/Controllers/AccountController.cs`](https://github.com/khutyu/marketplace/blob/master/MarketPlace/Controllers/AccountController.cs) (Account actions)
