I have a data model dll and an seperate admin data model dll. I always get errors when I try to implement DataSource extension.
 
ServerService.exe.config:
 
  <connectionStrings>
    <add name="VisitrackEntities_A1" connectionString="metadata=res://*/VisitTrack.csdl|res://*/VisitTrack.ssdl|res://*/VisitTrack.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=DEVSERVER\DEVSQL;Initial Catalog=Visitrack;User Id=localdev;Password=anotherhotday;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
    <add name="FPServicesEntities_B" connectionString="metadata=res://*/FPServicesEDM.csdl|res://*/FPServicesEDM.ssdl|res://*/FPServicesEDM.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=DEVSERVER\DEVSQL;Initial Catalog=Visitrack;User Id=localdev;Password=anotherhotday;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />

After research and investigation, I find this is caused by the FPServicesEntities domain model. We created the FPServicesEntities model project by using old version of IdeaBlade (possibly 6.0.3). The domain model Visitrackentities is created by using 6.0.4. I got the error above, when I deploy them into the BOS (6.0.4) server. The problem goes away when I re-recreate the FPServicesEntities model using 6.0.4 and deploy to BOS server.
 
It looks there is a problem on version compatible upwards (downwards).

Yes, the same version of DevForce should be used on the client and server.
