I have developed an application using SDK 4.0 for Microsoft Dynamics. Application is big and komplex and It would take a lot of time to redevelope the whole application with SDK 2011. But since last month new users can register Dynamics crm online only integrated with Office 365 (available on the german version of registration site for crm online). Unfortunately Microsoft says:
"The 2007 service endpoints are not supported in Microsoft Office 365 organizations. The 2007 Discovery service (CrmDiscoveryService.asmx) does not return Office 365 organizations and you cannot use the CrmService.asmx and MetadataService.asmx services with an Office 365 organization." (MSDN)
How can I avoid redevelopment of my application?
