title: SQLConnection not part of System.Data.SqlClient in VS 2019?
body: <p>I am using Visual Studio 2019, C#, and added</p>
  <pre><code>Using System.Data.SqlClient;
  </code></pre>
  <p>When I use the following code:</p>
  <pre><code>SqlConnection cnn;
  </code></pre>
  <p>I get the error:</p>
  <blockquote>
  <p>Severity  Code    Description Project File    Line    Suppression State
  Error CS1069  The type name 'SqlConnection' could not be found in the
  namespace 'System.Data.SqlClient'. This type has been forwarded to
  assembly 'System.Data.SqlClient, Version=4.6.1.0, Culture=neutral,
  PublicKeyToken=b03f5f7f11d50a3a' Consider adding a reference to that
  assembly</p>

  <p>Is the SqlConnection type no longer part of the Data SQLClient in Visual Studio 2019?</p>
