A tool to help you manage calendar imports from Microsoft Outlook to Google Calendar.

You will need to setup MongoDB accordingly to http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/ or to http://docs.mongodb.org/manual/tutorial/install-mongodb-on-windows/#manually-create-windows-service otherwise the library won't work.

Also, to compile the library you'll also have to install http://msdn.microsoft.com/en-us/library/15s06t57.aspx (Microsoft Office Interop Assemblies) which are used by the OutlookCalendarManager to interact with Outlook and its calendar service.

Each calendar "manager" derives from ICalendarManager interface, that forces you to implement these generic functions:

• Push
• Pull and Pull with begin date and end date.
• and their Async versions (PushAsync and PullAsync).

Each calendar manager provides an instance (singleton) that lets you pull its calendar into a GenericCalendar object, which is then pushable inside a new calendar manager, without any further modifications:

// take events from outlook and push em to google
var calendar = await OutlookCalendarManager.Instance.PullAsync() as GenericCalendar;
var googleCalId = await GoogleCalendarManager.Instance.Initialize(calId, calName);
if(!GoogleCalendarManager.Instance.LoggedIn)
{
	var login = await GoogleCalendarManager.Instance.Login(clientId, secret);
}
if (login) //logged in to google, go on!
{
	var ret = await GoogleCalendarManager.Instance.PushAsync(calendar);
	if (ret) Log.Info("Success");
}

If you want to integrate your application inside a service or whatsoever a timed event is provided by using a subscription policy:

var googleCalId = await GoogleCalendarManager.Instance.Initialize(calId, calName);
if(!GoogleCalendarManager.Instance.LoggedIn)
{
	var login = await GoogleCalendarManager.Instance.Login(clientId, secret);
}
OutlookCalendarManager.Instance.Subscribers = new List<ICalendarManager>
{
	GoogleCalendarManager.Instance
};
if (login) { OutlookCalendarManager.Instance.StartLookingForChanges(TimeSpan.FromSeconds(10)); }

OutlookCalendarManager now holds a list of subscribed calendar managers and every N milliseconds/seconds/minutes/hours/whatever (see arguments for StartLookingForChanges) it will look for changes inside their managed calendar and push the changes inside their subsribed calendar managers.

• Outlook => Google calendar import works successfully.
• Google => Outlook calendar import is not yet implemented.

If you have any calendar service you would like to implement feel free to contribute.
