When I created a strong view using the Quickfix context it blew up, because it was trying to associate a class that did not exists in the model. So by deleting all the extra DAL and Model Context, creating my view using the Entity.context that showed up in the Strong view menu everything worked just fine.
通过文本模板自动生成类能解决该问题。
The entity type <type> is not part of the model for the current context
