I've seen a lot of nopCommerce forums users asking how they can use Entity Framework (EF) Code-First Migrations to customize nopCommerce, add new fields and entites to the core. I actually use a lot of EF Migrations myself when doing nopCommerce customization projects, and I must say it helps a lot in the development.
Today, I'll share with you how you can do that in nopCommerce project! I'll be using nopCommerce 3.20 as an example, but you can easily apply the concept to other vesions!
Setting Up EF Migrations in nopCommerce Solution
The first thing you want to do is to enable migrations in your nopCommerce solution. So fire up nopCommerce in Visual Studio, look at Nop.Web project, and open Web.config. You need to add a connection string to your development database. Note that adding the connection string in Web.config doesn't affect how nopCommerce works, since nopCommerce doesn't look for connection string in Web.config.
