title: SqlDataAdapter type or namespace not found
body: <p>I want to connect my SQL Server database from my UWP app, but I keep getting the error that the <code>SqlDataAdapter</code> type or namespace not found and that my datagrid does not have a source. I added the <code>using System.Data.SqlClient</code> and <code>using System.Data;</code> statements. </p>
  
  <pre><code>string cs = "Data Source=.;Initial Catalog=Artist;Integrated Security=True";
  
  SqlConnection con;
  SqlDataAdapter adapt;
  DataTable dt;
  
  //frmSearch Load Event   
  private void frmSearch_Load(object sender, EventArgs e)
  {
      con = new SqlConnection(cs);
      con.Open();
  
      adapt = new SqlDataAdapter("select * from ArtistTable", con);
      dt = new DataTable();
      adapt.Fill(dt);
  
      ArtistGV.DataSource = dt;
      con.Close();
  }
  
  private void txtsearch_TextChanged(object sender, TextChangedEventArgs e)
  {
      con = new SqlConnection(cs);
      con.Open();
  
      adapt = new SqlDataAdapter("select * from ArtistTable where ArtistName like '" + txtsearch.Text + "%'", con);
      dt = new DataTable();
      adapt.Fill(dt);
  
      ArtistGV.DataSource = dt;
      con.Close();
  }
  </code></pre>
