Hi folks,
Marco says on page 52 of his book that ArticleProvider (which is a base class to sqlArticleProvider has an Instance static method that
returns an actual instance of the correct class
"according to what's specified in the configuration file"

however I stepped through this and when I get to the Instance property:

           _instance = (ArticlesProvider)Activator.CreateInstance(
                  Type.GetType(Globals.Settings.Articles.ProviderTyp e));
            return _instance;
         }
      }


the Globals.Settings.Articles.ProviderType in the immediate window returns

"MB.TheBeerHouse.DAL.SqlClient.SqlArticlesProvider "

but this string isn't in any configuration file that I can find...it's in a class called ConfigSections in ConfigSections.cs in app_code folder

  [ConfigurationProperty("providerType", DefaultValue = "MB.TheBeerHouse.DAL.SqlClient.SqlArticlesProvider ")]
      public string ProviderType
      {
         get { return (string)base["providerType"]; }
         set { base["providerType"] = value; }
      }

is this a typo on Marco's behalf or is this fully qualified classname in a configuration file as well and I just can't find it

I understand the elegance of what he's trying to do with the abstract classes and separating the DAL from the BLL etc...it's just that I want to make sure that I'm not missing something as to exactly where this setting is stored...


Many thanks in advance for any clarifications,
Regards

He plugged in a custom configuration provider via web.config. It's a cool idea.

It's a little overkill for a site like this, but he did it to teach us how its done.

thanks for answering englere, but that was my exact question, as I can't find the string in the config file, because it's not there, but it is in the default value of the attribute in the class that inherits from configurationSection...any ideas?
