title: ConnectionString Builder in Entity Framework Core 2
body: <p>I'm trying to convert an old project c# to asp net core and to the EF core 2.0 and I can't find the EntityConnectionStringBuilder.</p>
  
  <pre><code>public string GetEntityConnectionString(string databaseName, string metadata)
  {
      string providerName = "System.Data.SqlClient";
      string providerString = GetConnectionString(databaseName);
  
  
      System.Data.Entity.Core.EntityClient.EntityConnectionStringBuilder entityBuilder =
      new System.Data.Entity.Core.EntityClient.EntityConnectionStringBuilder();
  </code></pre>
  
  <blockquote>
    <p>Error CS0234  The type or namespace name 'Entity' does not exist in the
    namespace  'System.Data' (are you missing an assembly reference?)</p>
