No executable found matching command "dotnet-ef" (Csproj) - macos

Question

I started a project on a Mac using VS Code and ASP.NET Core MVC, here is my csproj:
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore" Version="1.1.1" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.2" />
<PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="1.1.1" />
<PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="1.1.1" />
<PackageReference Include="Microsoft.VisualStudio.Web.BrowserLink" Version="1.1.0" />
<PackageReference Include="Microsoft.AspNetCore.Authentication.Cookies" Version="1.1.0" />
<PackageReference Include="System.Data.SqlClient" Version="4.3.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="1.1.1" PrivateAssets="All" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="1.1.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="1.0.0" />
</ItemGroup>
I always get "No executable found matching command "dotnet-ef""
I tried it on Windows 10 and I get the same result.
What am I missing?

Answer 1

Added this to make it work:
<ItemGroup>
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version = "1.0.0"/>
</ItemGroup>

Answer 2

From inside the folder containing the csproj file, Add the following to the csproj file:
<PropertyGroup>
<TargetFramework>netcoreapp2.0</TargetFramework>
<RuntimeFrameworkVersion>2.0.5</RuntimeFrameworkVersion>
</PropertyGroup>
<ItemGroup>
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />
</ItemGroup>
Now include the needed dependencies by executing the following commands:
dotnet add package Microsoft.EntityFrameworkCore
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet add package Microsoft.EntityFrameworkCore.SqlServer
dotnet add package Microsoft.EntityFrameworkCore.Tools.DotNet
Restore the project so that all dependencies are checked upon
dotnet restore
In order to make sure it all went ok, run the following command
dotnet ef
A screen with the basic dotnet ef command usage should appear
Check if the project is still building:
dotnet build
Generate the scaffold from your database with the following command:
dotnet ef dbcontext scaffold "Server=<your_server_address[,port_number]>;Initial Catalog=<your_db>;User Id=<your_user>;Password=<your_password>" Microsoft.EntityFrameworkCore.SqlServer -f -c YourDbContext -o Db --json
The command above can be described as the one responsible for reading out your database and generating your scaffold poco entity classes and the dbcontext file. It requires a basic working connection string, the parameter f forces the overwrite, the c gives the context a name, the o determines the output folder and the namespace for the created classes and the json parameter outputs the command result in json instead of a zero stout.
it is nice to keep this command at hand, it will be used anytime changes from the database must be reflected upon the ORM
