Entity Framework Core - No executable found matching command "dotnet-ef"

After adding the EntityFramework nuget package to my ASP.NET Core project and creating our DbContext(see below) I was ready to generate a first migration :

	public class BloggingContext : DbContext
	{
	public BloggingContext(DbContextOptions<BloggingContext> options)
	: base(options)
	{ }
	public DbSet<Blog> Blogs { get; set; }
	public DbSet<Post> Posts { get; set; }
	}
	public class Blog
	{
	public int BlogId { get; set; }
	public string Url { get; set; }
	public List<Post> Posts { get; set; }
	}
	public class Post
	{
	public int PostId { get; set; }
	public string Title { get; set; }
	public string Content { get; set; }
	public int BlogId { get; set; }
	public Blog Blog { get; set; }
	}

I opened the Package Manager Console in Visual Studio, browsed to the project folder(!),  and executed dotnet ef. I ended up with the following error message:

dotnet : No executable found matching command "dotnet-ef"

At line:1 char:1

To solve this install the following 2 extra packages:

• Microsoft.EntityFrameworkCore.Tools: Contains the Entity Framework Core Package Manager Console Tools. Includes Scaffold-DbContext, Add-Migration, and Update-Database.
• Microsoft.EntityFrameworkCore.Tools.DotNet: Contains the Entity Framework Core .NET Command-line Tools. Includes dotnet-ef.

Remark: When trying to install the Microsoft.EntityFrameworkCore.Tools.DotNet package, I got the following error message:

I solved it by adding the package directly to the csproj file:

	<ItemGroup>
	<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.2" />
	</ItemGroup>

After doing that run a dotnet restore first. If you now try to execute dotnet ef, it should work:
