Watches eCommerce
https://github.com/Jamal40/AwesomeWatchesAwesomeWatches is a simple eCommerce app. I set it up so the user can add items to the cart and view cart items. They can see how much the items cost in total. The project has another section, which is the admin pages. The admins must be authorized to manipulate the item data on these pages. The project utilizes two major ASP web app models (ASP and MVC Razor). ASP.NET Core was used to build the application( MVC and Razor Pages).
The database used is Microsoft SQL Server and Entity Framework Core to access it. The default CSS library used by ASP was initially Bootstrap. However, I removed it and used Materialize instead. It was a very excellent experience. I also used Pixlr to edit images and logos.
