Starting with SQL Console app

Starting using VS 2017 console app:

 A site to look at:

https://ef.readthedocs.io/en/staging/platforms/full-dotnet/existing-db.html

In console app… using the Package Manager

Install-Package Microsoft.EntityFrameworkCore.SqlServer
Install-Package Microsoft.EntityFrameworkCore.Tools
Install-Package Microsoft.EntityFrameworkCore.SqlServer.Design

Database 1st – Scaffold it…

Scaffold-DbContext "Server=Orion;Database=ScottDB;Integrated Security=False;
User ID=sa;Password=****" Microsoft.EntityFrameworkCore.SqlServer

**Note nvarchar types have issues in the Entity definition, and regardless what the “InterTubes” say- .HasColumnType and .HasColumnSize – does NOT work.

Sample Connect string

Data Source=ORION;Initial Catalog=ScottDB;Integrated Security=False;
User ID=sa;Password=********;Connect Timeout=30;Encrypt=False;
TrustServerCertificate=True;ApplicationIntent=ReadWrite;MultiSubnetFailover=False

Don’t forget Migrations. These can still be useful to keep your code and DB in sync.
