I am using VS2015 update 3.

I have .NET Core 1.1.1 installed

Here are contents of related folder.

Problem is that I am not able to reverse engineer the database. Below is what I am getting when I am running command against my ASP.NET Core project.

PM> Scaffold-DbContext "Server=MY-PC;Database=MyDatabase;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models 
Startup project 'src\MyProject' is an ASP.NET Core or .NET Core project for Visual Studio 2015. This version of the Entity Framework Core Package Manager Console Tools doesn't support these types of projects.

What I am doing wrong here?

Answer 1

You cannot use Scaffold-DbContext PM because this tool doesn't support VS 2015 project but you can use dotnet ef dbcontext scaffold instead
Entity Framework Core Scaffold DbContext from Existing Database

sample :

dotnet ef dbcontext scaffold "Server=MY-PC;Database=MyDatabase;Trusted_Connection=True;" -o Models Microsoft.EntityFrameworkCore.SqlServer
