Unable to generate model from database in Visual Studio 2017 RC

Question

I followed the official Microsoft tutorial for Entity Framework Core database first approach available in this link.

When I try to execute the below command to generate the model from the database:

Scaffold-DbContext "Server=Data Source=DESKTOP-COJD62N;Initial Catalog=TrainGameDB;Integrated Security=True" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -context TrainGameContext -Verbose

I am getting the following output:

Build started...
Build succeeded.
dotnet exec needs a managed .dll or .exe extension. The application specified was 'F:_IIT Level 6\UX\CW2 Backend\App2\TrainGameAPI\src\TrainGameAPI\bin\Debug\netcoreapp1.0\TrainGameAPI.runtimeconfig.json'
Process finished with non-zero exit code

I am using:

Visual Studio 2017 RC

SQL Server 2016 Developer

.NET Core 1.1.0 (I uninstalled version 1.0.1 and installed this)

ASP.NET Core Web API Application

Windows 10 Education
