Just got back from the Microsoft Technical Conference 2011 in Nice and attended a lot of Sessions with three of my colleagues. Here are already some interesting things to remember, I’ll try to add more later.
Microsoft Announced Information Source (beta). All users that have access to CustomerSource or PartnerSource can use their login to access this site. The site is a set of tools to make predictable implementations. Also under Services you can find a Beta version for the Intelligent Data Management Framework (IDMF), Code Upgrade Service and the Security Advisor Upgrade Tool for Microsoft Dynamics Ax 2012.
When you make modifications to standard Ax, try to use events where possible. You can use delegates or pre-/post events. This should make upgrading easier in the future.
Also MPF presented a session on how a ISV can creat its solution. You can find part of the demo here.
This is a start and I hope to post more details about the sessions I attended soon.
