Awesome, great work. Now all you have to do is get XPO Linq to support subqueries and I and a lot of people will be very happy!

Is there a way to connect to Sybase ASA11? Or any way to get my own ConnectionProvider into the XPOContextDriver?

Hello Yaron,

We developed and tested XPOContextDriver with both v4.31.0 and v2.31.0 versions of LINQPad, and it worked fine. If you have any difficulties using our XPOContextDriver, please contact our support team at devexpress.com/.../Center. We will do our best to help you.

The driver is not working with LINQPad 4.31 (latest version). LINQPad says it loads it successfully, but it is nowhere to be found in the list of available drivers. After poking around the LINQPad forums, it seems that this is a problem with the DevExpress assembly, and it needs to be updated.

DevExpress.Xpo.XPCollection' does not contain a definition for 'Where' and no extension method 'Where' accepting a first argument of type 'DevExpress.Xpo.XPCollection' could be found (press F4 to add a using directive or assembly reference)

Did you modify the business objects of MainDemo assembly?

I am afraid the Auto-generated Int64 keys do not work with PostgreSQL (we are using the Ngpgsql ODBC provider v2.0.11.92 + PostgreSQL 9.1.2).

The table column for the auto-generated primary key of type int64 in the base class is incorrectly generated as integer, although in all inherited classes the table column for this field is correctly generated as bigint.

Nevertheless, even though the above sample does not work with PostgreSQL I must point out that the auto-generated primary key of type int64 is correctly generated as bigint in Microsoft SQL Server as advertised (i.e. the above sample code works flawlessly with MS SQL, just not with PostgreSQL).

Hi guys, i would like to know if some can point me to some examples of using WCF + the Noemax library and use it with XPO.

i has been able to work with IDataStore and WCF and i would like to use the Noemax library to improve performance.

Thanks
