title: Keyword not supported: 'provider'. Opening SqlConnection
body: <p>I don't know why this error, I tried everything. I want to connect my webForm to the Database .accdb
  and when I use using(){} I got this error "Keyword not supported: 'provider"
  Here is the code:</p>
  
  <p><strong>web.config</strong></p>
  
  <pre><code>&lt;connectionStrings&gt;
      &lt;add name="ConnectionString"
      connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Manuel_2\Documents\Login.accdb"     
      providerName="System.Data.OleDb" /&gt;
  &lt;/connectionStrings&gt;
  </code></pre>
  
  <p><strong>WebForm1</strong></p>
  
  <pre><code>private static string conDB =        
              ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;    
  
  protected void Page_Load(object sender, EventArgs e)
  {    
     using (SqlConnection con = new SqlConnection(connDB))  //here is the error
     {
         // .....                            
     }              
  }
  </code></pre>
