Entity Framework Database First .Net5 (Easy Setup and Usage)

Entity Framework Database First .Net5 setup and usage. I go through a basic MVC project built in .Net5 (dotnet5) and add Entity Framework to it the easy way. Also this will show you how to add additional tables to it later without having to rerun any heavy commands by using an extension that does some reverse-engineering. This works for beginners and those new to dotnet5 and/or dotnet core.
