Baffling static property issue.

[Steve]

I'm currently running into a problem, and I have no idea what to make of it.

I have a class with nested clases and static properties that I'm using
to store configuration information using a custom configuration section.
When my code accesses one of the static properties the static
constructors are fired, and the code goes in and pulls the data from the
configuration section.

In the current instance, I'm getting a connection string. The call is
made to the static property. When the code returns the property value,
it is an empty string. If I type
Config.Connecti onStrings.Authe nticatedUser in the Command Window while
debugging the proper connection string value is present.

I have tried placing multiple calls to the property in my code to see if
something wasn't be initialized properly on the first call.
Unfortunately the behavior is the same everytime. Call from code, get an
empty string. Call from the Command Window, get the expected value.

Does anyone have any idea what might be going on here? Below is the code
that I'm using.

Thanks,
Steve
public class Config {

static Config() {
object config = ConfigurationSe ttings.GetConfi g("SystemConfig ");

if (config == null) {
throw new ConfigurationEx ception("No SystemConfig section was
specified.");
}
}

public object Create(object parent, object configContext,
System.Xml.XmlN ode section) {
//Get the connection strings
string authenticatedUs er = ConfigurationPa rser.GetAttribu te(section,
"AuthenticatedU ser", true);
string unauthenticated User =
ConfigurationPa rser.GetAttribu te(section, "Unauthenticate dUser", true);
ConnectionStrin gs.SetConnectio nStrings(authen ticatedUser,
unauthenticated User);

return true;
}

internal static void Load() {}

public class ConnectionStrin gs {
private static string _AuthenticatedU ser = "";
private static string _Unauthenticate dUser = "";

static ConnectionStrin gs() {
//Used to get the static Config constructor to fire.
Config.Load();
}

internal static void SetConnectionSt rings(string authenticatedUs er,
string unauthenticated User) {
_AuthenticatedU ser = authenticatedUs er;
_Unauthenticate dUser = unauthenticated User;
}

public static string AuthenticatedUs er {
get {return _AuthenticatedU ser;}
}

public static string Unauthenticated User {
get {return _Unauthenticate dUser;}
}
}
}

Steve,

Config.Create, which does the actual loading of the config data, is
never called by either Config or ConnectionStrin gs.

Config.Create does not need to be called manually. It is called when
ConfigurationSe ttings.GetConfi g(string) is called, dependent on what is
configured in the application's config file, in the configSections block.

I'm able to watch the code go through the Create routine everytime while
in the debugger, so that doesn't appear to be the problem.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

Steve,

Sorry about that. I'm not as well informed about dynamic
configuration properties as I like to think I am :-).

I believe the custom section handler class Config needs to explicitly
declare it is implementing IConfigurationS ectionHandler in order for
its Create method to be called. Something like this:

public class Config : IConfigurationS ectionHandler
