You can use CodeSmith or T4 Templates to generated the required code. Unfortunately OpenAccess does not provide any templates for MVVM infrastructure out of the box.
In case you decide to build your own templates, we at OpenAccess team and the whole community will be happy if you share the results.
If you need any assistance in creating the template you are welcome to post your questions here in the forum or in our customer support forum.
