/// The Maestro.Local provider (that wraps mg-desktop) and Maestro.LocalNative providers (that wraps the official MapGuide API)
/// are unique in that it has global connection state. What this means is that subsequent connections after the first one for
/// these providers may re-use existing state for the first connection. The reason for this is that creating this connection
/// internally calls MgdPlatform.Initialize(iniFile) and MapGuideApi.MgInitializeWebTier(iniFile) respectively, that initializes
/// the necessary library parameters in the process space of your application. Creating another connection will call
/// MgdPlatform.Initialize and MapGuideApi.MgInitializeWebTier again, but these methods are by-design only made to be called once
/// as subsequent calls are returned immediately.
///
/// Basically, the connection parameters you pass in are for initializing the provider the first time round. Subsequent calls may not
/// (most likely will not) respect the values of your connection parameters.
