Data Services Wizard fails

[Morgan]

I have a rlinq model I am trying to hook up to a Silverlight application. When I go to Data Services Wizard and hit next (using all defaults), I get the following error:

No description found.
Original error text: 'No metadata has been registered for class xxxxx.Web.EASI2011. (This usually indicates, that either this class is not declared persistent or it is declared persistent but not enhanced. The class was loaded from xxxxx

I am just walking through a tutorial and do not know what declaring something persistent (I do not see any options in the designer) or enhanced actually means. What is the best way to do either of these things?

Hello Morgan,

Can you please check if the following entry exists in your project file (.csproj or .vbproj) for the project where the Domain Model you want to expose through a service resides?

<Import Condition="Exists('$(MSBuildExtensionsPath)\OpenAccess.targets')" Project="$(MSBuildExtensionsPath)\OpenAccess.targets" />

If it doesn't exist, please add it and try again. 

More information about the Enhancer tool can be found here.

I am looking forward to your feedback.
