Hello Garry Clark,
Currently the functionality you require is not directly exposed through the new context. However, you can create a partial class which extends the generated Entity Diagrams context and expose the protected method GetScope() to retrieve an instance of the old scope.
NorthwindContextWithScope : NorthwindContext
Here we assume that NorthwindContext is the generated class which extends OpenAccessContext. With the IObjectScope available you can make use of the GetSqlQuery method as well as some other functionality which you feel is missing.
Should you want to know something else, do not hesitate to contact us.
