Will the generated classes (and collections of them) implement IQueryable and be able to be used with LINQ?

Reply to comment question: Will the generated classes (and collections of them) implement IQueryable and be able to be used with LINQ?

In the current CTP, Linq To Objects is supported over the Jasper API. This is comparable to what is currently offered with Linq over DataSet and Linq over XML.

We did a bunch of work to hook up the Queryable support in Jasper – essentially the ability to translate the Linq queries to the backend query language, however due to limitations in VB9 and Python 1.1 we were not able to include this feature in the CTP release. Essentially the problem bolis down to the fact Linq (as currently is) requires queries to be statically typed - and Jasper is based on runtime type generation. Supporting Linq in Dynamic Languages (VBX, IronRuby, IronPython) is very important and currently there is a ongoing cross team effort to get this working.

The CTP release does fully support Entity Sql. Since this query language applies to the conceptual model and not the runtime types, it is not hampered by the need for static types.

As far as I could see in the sample code, the way queries are performed in Jasper are not too different to the "list comprehension" fetures of python.

Would it be possible to use this syntax instead?

That would be great and way more intuitive for python programmers...
