Hi Imar:

I am trying to view the chapter 19 example code in VS 2010 and I get the following error:

Parser Error Message: Could not load type 'System.Data.Entity.Design.AspNet.EntityDesignerBu ildProvider'.

pointing to the following web.config code:

[code]Line 50: <add extension=".edmx" type="System.Data.Entity.Design.AspNet.EntityDesig nerBuildProvider"/[code]

Am I missing something simple?

Thanks,
Clark

Hi Clark,

There was a slight change in behavior between the latest version of VS the source was compiled against and the final release version of Visual Studio. I fixed the source code a few days ago after I found out about the issue and submitted a new version to Wrox. It should be on-line tomorrow.

In the mean time, you can download the latest versions here:

Sorry for the inconvenience...

Cheers,

Hi again Imar,

Many thanks for your quick response. I haven't tried it out yet, but I'm sure it will work for me. I went back to chapter 14 and started over there and ran into another problem.

This may be the same problem. In the Try It Out step 8. where it says

"Enable inserting for the DetailsView control by checking the item Enable Inserting on the same Smart Tasks panel."

There isn't any Enable Inserting on the smart panel. The resultant code doesn't get the following bold underline italic parts:

Code:

<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
      <asp:CommandField ShowInsertButton="True"/>

Code:

 DefaultContainerName="PlanetWroxEntities" EnableFlattening="False"  EnableInsert="True"
    EntitySetName="PhotoAlbums" OnInserted="EntityDataSource1_Inserted">

Excelsior!
Clark
