The CRM SDK team released version 5.0.7 of the SDK and this version includes a lot of new things that incides with UR 5 and the CRM Online November Service Release. You may download the new SDK from MSDN library and also on MSDN download.
Also the CRM Engineering for Enterprise Team and the CRM Content Publishing Team release a white paper today on Deploying Microsoft Dynamics CRM 2011 and CRM Online Solutions from Development through Test and Production Environment, which is available for download from the Microsoft Download Center.
This white paper explores deploying real-world Microsoft Dynamics CRM solutions across test and production environments in reliable and repeatable ways by using automation. The paper also provides some automation example and highlights the specific constraints associated with deploying and testing solutions in a Microsoft Dynamics CRM Online environment.
Thanks to the CRM team for the opportunity to contribute to this white paper. Couple of my colleagues and myself contributed to this paper as well!
