Efcore: Error Installing EFCore: This version of the Entity Framework Core Package Manager Console Tools doesn't support these types of projects

Created on 6 Apr 2017 · 2Comments · Source: dotnet/efcore

While trying to install EntityFrameWorkCore for a new MVC-project in VS2015, I get this error. Nuget is updated to version 3.5.

PM> Update-Database
Startup project 'src\G07' 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.

Steps to reproduce

Create new MVC-project, install EFCore packages, updated everything to 1.1.1. Here's my version and project.json. Can anyone assist? Thanks!

PM> dotnet --version
1.0.0-preview2-003131
