Talvolta l'installazione di "Windows Communication Foundation" (a.k.a.
Indigo) su Windows XP può fallire almeno in parte, anche se il setup dichiara
che è tutto ok. Da cosa ce ne accorgiamo? Indubbiamente dal fatto che
qualcosa va storto ...
Infatti, mi si è presentato questo errore in fase di compilazione:
Unhandled Exception: System.TypeInitializationException: The type initializer for 'System.ServiceModel' threw an exception. ---> System.Configuration.ConfigurationErrorsException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException: Unrecognized configuration section system.serviceModel. () at System.Configuration.BaseConfigurationRecord.ThrowIfInitErrors() at System.Configuration.ClientConfigurationSystem.EnsureInit(String configKey) --- End of inner exception stack trace --- at System.Configuration.ClientConfigurationSystem.EnsureInit(String configKey) at System.Configuration.ClientConfigurationSystem.System.Configuration.Internal.IInternalConfigSystem.GetSection(String sectionName) at System.Configuration.ConfigurationManager.GetSection(String sectionName) at System.Configuration.ConfigurationManager.get_AppSettings() at System.ServiceModel.DiagnosticTrace..cctor() --- End of inner exception stack trace --- at System.ServiceModel.DiagnosticTrace.ShouldTrace(TraceEventType type) at System.ServiceModel.ServiceHost.TraceCreation(TraceEventType eventType) at System.ServiceModel.ServiceHost..ctor(Uri[] baseAddresses) at System.ServiceModel.ServiceHost`1..ctor(Uri[] baseAddresses) at Service.Program.Main(String[] args) ....
Questo perchè l'installazione non è riuscita a registrare le sezioni di
indigo nel machine.config. E' sufficiente aggiungere al machine.config, nella
sezione configSections, il seguente codice:
