Extension method for adding export hbm from fluent nhibernate when in a debug environment

Came up with a useful little extension method today. I wanted the fluent nhibernate configuration to export the hbm files when the site is being run in debug mode.

   1: /// <summary>

   2: /// Export hbm to path if debug environment

   3: /// </summary>

   4: /// <param name="fluentMappingsContainer">Container</param>

   5: /// <param name="path">Path</param>

   6: /// <returns>container</returns>

   7: public static FluentMappingsContainer ExportPathIfDebug(this FluentMappingsContainer fluentMappingsContainer, string path)

   8: {

   9:     #if DEBUG            

  10:     if (ConfigurationManager.AppSettings[path] != null)

  11:     {

  12:         if (!Directory.Exists(ConfigurationManager.AppSettings[path])) Directory.CreateDirectory(ConfigurationManager.AppSettings[path]);

  13:         fluentMappingsContainer.ExportTo(ConfigurationManager.AppSettings[path]);

  14:     }

  15:     #endif

  16:     return fluentMappingsContainer;

  17: }

Where the path refers to an application setting in the app.config.
