Google has launch GO Contact Sync Mod

The newest versions of Google APIs client Library for .NET dropped support for .NET 4.0.

Minimum requirement for GO Contact Sync Mod (starting with v3.10.0) is .NET 4.5 which is not working on Windows XP.

If you want to support the project please email us!
At the moment we have not enough free time to continue the development and answering of your questions.
GO Contact Sync Mod synchronizes your Microsoft Outlook contacts with your Google Mail address book, including pictures, categories and notes.
Since version 3.7.0 it also syncs your Outlook Calendar Appointments on demand to Google Calendar. This Mod fork adds many enhancements and bug fixes to the obviously dead project 'Go Contact Sync'.
