I have created a Class Library project with the following .csproj:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netcoreapp1.1</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.sqlserver.Design" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="1.1.0" />
</ItemGroup>
</Project>
When running the command:
Add-Migration -Name Test -Context TestContext
I am getting the following error:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.EntityFrameworkCore.Design, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

However Microsoft.EntityFrameworkCore.Design is already installed.
I am using Visual Studio Community 2017 (VisualStudio/15.0.0+26228.9)
What am I missing?
It worked after adding Microsoft.EntityFrameworkCore.Tools.DotNet and changing the versions of dotnet tools to 1.0.0-msbuild2-final, now my .csproj is:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netcoreapp1.1</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.sqlserver.Design" Version="1.1.1" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="1.0.0-msbuild2-final" />
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="1.0.0-msbuild2-final" />
</ItemGroup>
</Project>
