I get the following exception logged to event viewer when spinning up WCF SVCs for EntityServer and EntityService
 
Event Type: Error

I did a quick object search for RemoteEntityService' in the Entity.Server assembly and no such class was found. What am I missing?

Start with a working IIS Deployment.  Use the 110_Deployment example ("300COR_DeploymentWithIIS") example in the Learning Resources folder.  Unfortunately, this example does not work because the database login will fail as it uses Windows Security.  To fix the problem, change the database connection string by replacing "Integrated Security=True" with a correct SQL Server password string (e,g., "User=sa;Password=foo;"
 
Look at the Deployment.pdf document as well.  The documentation is correct as far as it goes, but unfortunately the discussion of WCF is very sparse.

RemoteEntityService is an internal class in the IdeaBlade.EntityModel.Server assembly.  The EntityService.svc file contents should look something like this:
 
   < mailto:%@ServiceHost - %@ServiceHost language="C#" Service="IdeaBlade.EntityModel.Server.RemoteEntityService" %>
 
(The language can be either C# or VB.)
 
We haven't seen this problem before, but a few things to check -
  • Make sure all required IdeaBlade assemblies are in bin or the GAC.  (These are IdeaBlade.EntityModel, IdeaBlade.EntityModel.Edm, IdeaBlade.EntityModel.Server, IdeaBlade.Linq, IdeaBlade.Valdiation, and possibly IdeaBlade.EntityModel.Web if using ASP.NET security.)
  • If you've precompiled your web site that might be the problem.  This link may help - http://social.msdn.microsoft.com/forums/en-US/wcf/thread/8c897f8e-2143-450e-a9f4-97d1f8702da7/ - http://social.msdn.microsoft.com/forums/en-US/wcf/thread/8c897f8e-2143-450e-a9f4-97d1f8702da7/
