Issue Title

Just published a console app using Microsoft.Data.SqlClient V2.0.0 and runtime fails to run when: <PublishSingleFile>true</PublishSingleFile>

General

I have tried with and without <IncludeSymbolsInSingleFile>true</IncludeSymbolsInSingleFile>

The error is
An assembly specified in the application dependencies manifest (MyApp.deps.json) was not found:
package: 'Microsoft.Data.SqlClient.SNI.runtime', version: '2.0.0'
path: 'runtimes/win-x64/native/Microsoft.Data.SqlClient.SNI.pdb'

For some issues, you will get a quicker and better response if you file it at a more specific .NET repo. For example, if the problem is with ASP.NET Core, you are encouraged to use the aspnet/home repo.
