About Dynamic Data in Visual Studio 2010 / .NET 4



Does anybody here have any pointers to screencasts, demos, webcasts for the latest enhancements in Dynamic Data as listed in above link? I'm repeating them here for ready reference :


  • EnableDynamicData method which enables Dynamic Data features in existing ASP.NET applications and DataSource controls
  • A new QueryExtender control, contained in the sample projects to simplify common data filtering operations. It supports a rich ASP.NET declarative query syntax that makes it easy to do things like search data for text or have filters based on ranges
  • A new Dynamic Data filter model that enables the developers to apply templates to pages just like field templates (including user defined filters)
  • New field templates of Email, URL and Enum columns
  • Support for inheritance in Entity Framework and Linq to SQL
  • Support for many to many relationships in Entity Framework
  • New Entity Templates which allow fine control over how an object is displayed and edited
  • DynamicHyperLink control for building links to tables and actions
  • Declarative support for D

Linq qry with order by basic questions


I have never tried a group by with linq, now I do and I'm stuck.

I try to convert this sql statement to its linq counterpart :

SELECT COUNT(tb_Mailer_Smses.Id) AS [cnt], tb_Mailer_mailing.Id As [Id]
,SUM( CASE WHEN tb_Mailer_smses.DLRStatus = 200 THEN 1 ELSE 0 END) As [Delivered]
FROM tb_Mailer_mailing INNER JOIN
tb_Mailer_Smses ON tb_Mailer_mailing.Id = tb_Mailer_Smses.MailingId
WHERE tb_Mailer_mailing.ApplicationId = 1
GROUP BY tb_Mailer_mailing.Id

Is there some one who can me show me the convertion process ?
