When will SQLClient be fully implemented?

[FredyWenger]

For new webservice-project, I want to use MVC6 (WebApi).
I work with Microsoft Visual Studio Professional 2015, Version 14.0.24720.00 Update 1, ASP.NET and Webtools 2015 (RC) 14.1.11116.0
I have still invested a few days and then seen, that SqlClient seems to bee implemented only "half" yet.
I have added the NuGet: System.Data.SqlClient (4.0.0.0.beta-23516) (latest available version) and added: using System.Data.SqlClient;
Some objectes like SqlCommand and SqlConnection are known, but other important objects like DataTable and SqlDataAdapter are not found.
As to access a SQL-Server from a webservice is a main reason ti build a webservice and we talk about a RC-version with support, SqlClient should be added fully ASAP.
**So my question:

• Is it planned to add full-support for SqlClient in the very near time?
  **
  Else I have to rebuild my webservice from scratch on the "old" plattform :-(
  *Thanks for a fast answer.

@FredyWenger the SqlClient library is part of CoreFX, so I recommend logging an issue at https://github.com/dotnet/corefx/issues/ to find out the latest info. Thanks!

It looks like you may have found some related issues discussing this already:

@Eilon
Thanks for your posting.
Unfortunately the first linked thread is closed already.
On the second linked thread, I have posted already a view days ago and received no answer :-(
I don't understand that... such an important thing is not included in a RC version...
However, as I don't receive any answer (I also have opened a MSDN-ticke with no usable answer), it seems as I have to stay away from MVC 6 (and loose my already done work to the web service!)
