Oliver Sturm's Expert eXpress Persistent Objects (XPO) Class - Bad Ems, Germany + SMALL BONUS

XAF Team Blog
31 January 2013

Join Oliver Sturm in Bad Ems, Germany for 2 days (February 28 - March 01 2013) of expert DevExpress eXpress Persistent Objects (XPO) training:

“This class is a deep dive into DevExpress eXpress Persistent Objects, short XPO. XPO is an object/relational mapping (ORM) tool with a brilliant feature set, lending itself equally well to small and large development projects. With its broad database and platform compatibility, XPO is a valuable proposition for many scenarios that competing tools don't cover. As the basis of the eXpressApp Framework (XAF) product, a business application framework also made by DevExpress, XPO has additional credibility. The class starts with the basics, but moves on quickly to advanced scenarios. As much as the two-day timeframe allows, no question about XPO shall remain unanswered!”.

There will be soon more great news from Oliver, but I would like to keep it secret for now, please stay tuned!:)

BTW, while we are talking about our frameworks, I would like point out the improvements we have made to these products in version 12.2.6 -  just released.

Here you can see the list of fixed issues (it is quite large so I will not post it here).

And below are the implemented suggestions:

eXpress Persistent Objects

  • S170602 - AdvantageConnectionProvider - Support Advantage Database 11.1 and .NET Framework 4.5
  • Q457118 - ORM Designer - Provide the capability to reorder fields
  • S170604 - ORM Designer - Provide the capability to set the UseAssociationNameAsIntermediateTableName property in the designer
  • S170549 - Provide a web service project template for creating an XPO OData Service that can also include a visual data model
  • S170635 - Support System.Data.SQLite v1.0.84.0

eXpressApp Framework

  • S170305 - BO Designer - Add a note to the ~.bo.designer.cs file that its modifications are prohibited
  • S170362 - Chart - Add Entity Framework support
  • Q458006 - Core - Add TargetObjectsCriteriaMode property to DevExpress.Persistent.Base.ActionAttribute
  • Q401329 - Deployment - Certain assemblies required for the deployment are missing in default project templates
  • S170364 - Pivot - Add Entity Framework support
  • S170227 - TreeList - Add Entity Framework support
  • Q442195 - Workflow - Ensure compatibility with WF 4.5 features

As you can see, we are continuing to polish the core, supporting new database engines and frameworks, improving designers and of course, empowering the Entity Framework support in XAF.
I hope you like these features. I look forward to hearing from you!

I have updated the link accordingly. Probably, you would also like to update your forum profile to indicate that you are again a part of the DevExpress family;-)
