We updated the Dynamic Data Preview 4 release last week to fix a couple of bugs that people in the forum have run into mainly around the DomainDataSource. You can download the new release here: http://aspnet.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27026.

Here is a list of the bugs that we fixed:

• DomainDataSource had errors updating foreign keys
• Cannot edit many to many relationship with table per type inheritance
• Better exception handling

Better exception handling

Hi, just curious, does this fix the incorrect behaviour that the ImprovedDynamicValidator solved?

I've been missing the ASP.NET Dynamic Data 4.0 Preview 4 (UPDATED 7/24) on CodePlex. Now that I have it, I fired off VS2008 SP1, to checkout one of the projects but then I ran into my first stumbling block on running the project :
 
Error 1 Could not load file or assembly 'System.ComponentModel.DataAnnotations, Version=99.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
C:\Documents and Settings\ujser\Desktop\ASP.NET Dynamic Data 4.0 Preview 4 Refresh\DynamicDataVNextSamples\DynamicDataSamples\web.config 44
 
The line 44 of web.config :
 
<add assembly="System.ComponentModel.DataAnnotations, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
 
What did I do wrong, or what do I need to do?

P.S. Has anybody done any videos to show off the new features of this Preview?
 
Thanks,
 
Mark
 

 Hi Mark, you need to load the Solution not the project as the missing referenced dll's are in the CommonFiles folder.

I realized that I needed the dlls from CommonFiles folder of the preview and so I dragged all of them to a bin folder of my project, after which those errors disappeared. But now I face another :-
 
Error 1 Could not load type 'DynamicDataProject.Global'. 
 
C:\Documents and Settings\ujser\Desktop\ASP.NET Dynamic Data 4.0 Preview 4 Refresh\DynamicDataVNextSamples\DynamicDataSamples\Global.asax 1 
 
Offending line was :-
 
<%@ Application Language="C#" CodeBehind="Global.asax.cs" Inherits="DynamicDataProject.Global" %>
 
I really think someone in the DD Team should do some videos to show off the new features as none of the videos in http://www.asp.net/dynamicdata show these features.
 
What do you say?
 
Mark

 Yes I had similar probs when I first downloaded, I now just unzip the whole thing and then open each part up by opening each solution file NOT the project files.

Steve,

That did it! Thanks
