title: Change connection string & reload app.config at run time
body: <p>When I change the connection string using this code, it does not reload <code>app.config</code> at runtime. I expected it to reload similarly to how we reload <code>app.config</code>.</p>
  
  <pre><code>config.ConnectionStrings.ConnectionStrings["JVVNL_NEW.Properties.Settings.JVVNL_NEWConnectionString1"].ConnectionString = ConString;
  config.ConnectionStrings.ConnectionStrings["CMS_NEW.Properties.Settings.JVVNL_NEWConnectionString1"].ConnectionString = ConString;
  config.Save(ConfigurationSaveMode.Modified,true);
  ConfigurationManager.RefreshSection(config.ConnectionStrings.SectionInformation.SectionName);
  </code></pre>
