Hello all,
We are receiving the No metadata has been registered error on our Windows 7 64-bit machines running the Q1 2012 version of Telerik ORM, VS 2008 and .NET 3.5, 4.0 is installed on the machine but is not being used. I checked for the enhancer code and it exists in the .csproj file.

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

If I go to a test box and recreate the same model using VS2010 there is no error and the project works fine. This appears to be a compatibility issue. 

Error
No metadata has been registered for class ClassLibrary2.Address. (This usually indicates, that either this class is not declared persistent or it is declared persistent but not enhanced. The class was loaded from file:

Any help you are able to provide is greatly appreciated.

Thank You
Jeff

Hello all,
We resolved this issue. The OpenAccess.targets file included with the Q1 2012 install for VS2008 uses the old venhancer and not the new enhancer. To fix this issue you have to get a copy of the OpenAccess.targets file that calls the enhancer. To do this I installed ORM on a VS2010 box and copied the file to my VS2008 box. Once this is done open the model again and switch from XML to attribute or the go the other way then save the model and rebuild the class. Once the class rebuild you can switch it back an rebuild it again. The issue should now be resolved.

Thanks
Jeff
