title: App.config - encrypted section error:
body: <p>I have an application that encrypts a section in the configuration file. In the first time that I try to read the encrypted section from the config file I get an error message: "Unrecognized attribute 'configProtectionProvider'. Note that attribute names are case-sensitive. "     </p>
  
  <pre><code>config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);  
  // Get the section in the file.   
  ConfigurationSection section = config.GetSection("EncryptedSection");
  
  
  if (section != null)      
  {           
      // Protect the section.
      section.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");
      section.SectionInformation.ForceSave = true;
  
      // Save the change.
  
      config.Save(ConfigurationSaveMode.Modified);  
  }  
  ConfigurationManager.RefreshSection("EncryptedSection");  
  Properties.Settings.Default.Reset();
  
  //This is the part where I read the encrypted section:
  
  ConfigurationManager.RefreshSection("EncryptedSection");
  System.Collections.IDictionary HSMMasterKeyConfig = (System.Collections.IDictionary)System.Configuration.ConfigurationManager.GetSection("EncryptedSection");
  </code></pre>
  
  <p>This only happens in the first time that I try to read the encrypted section. I have noticed that the .config file is getting updated immediately after the first save but from some reason I need to restart the application in order to use the encrypted section.</p>
