When adding Microsoft.EntityFrameworkCore.SqlServer.Design (2.0.0-preview1-final) to a project the following error occors on build:
Cannot find type Microsoft.EntityFrameworkCore.Metadata.RelationalFullAnnotationNames in module Microsoft.EntityFrameworkCore.Relational.dll
When only Microsoft.EntityFrameworkCore.SqlServer (2.0.0) is added the project builds (and runs) fine.
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer">
<Version>2.0.0</Version>
</PackageReference>
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer.Design">
<Version>2.0.0-preview1-final</Version>
</PackageReference>
<PackageReference Include="Microsoft.NETCore.UniversalWindowsPlatform">
<Version>6.0.1</Version>
</PackageReference>
System Info:
Microsoft.EntityFrameworkCore.SqlServer.Design:2.0.0 does not appear in the NuGet Package Manager:

Microsoft.EFCore.SqlServer.Design is not available in version 2.0, the code is included in Microsoft.EFCore.SqlServer 2.0
