We moved from Devforce 2010 to Devforce 2012 and updated to the latest version of cocktail. Now I am unable to log in. I am getting this error:

{IdeaBlade.EntityModel.EntityServerConnectionException: Unable to connect to EntityServer. Unable to start EntityServer.svc service: The service '/EntityServer.svc' cannot be activated due to an exception during compilation.  The exception message is: Type 'C5.HashSet`1+Feature[T]' cannot be exported as a schema type because it is an open generic type. You can only export a generic type if all its generic parameter types are actual types.. ---> System.ServiceModel.FaultException`1[IdeaBlade.EntityModel.EntityServerFault]: Unable to start EntityServer.svc service: The service '/EntityServer.svc' cannot be activated due to an exception during compilation.  The exception message is: Type 'C5.HashSet`1+Feature[T]' cannot be exported as a schema type because it is an open generic type.

I have no idea what 'C5.HashSet`1+Feature[T]' is?? We are logging in using html and then in the silverlight we are passing a null credential to pick up the logged in user. The login is working on the html but when we pass the null credentials we get the error.

I think DevForce is finding the C5.Hashset<T> in its enum search and then failing due to it.  You can set the CompositionHost.IgnorePatterns to exclude the C5 assembly from DevForce probing to work around the issue.  See http://drc.ideablade.com/devforce-2012/bin/view/Documentation/discovery for how to specify the IgnorePatterns.  This problem is occurring on the EntityServer so you can set the IgnorePatterns in the global application_start logic.  If you're also using the SL version of C5 you'll also need to set the IgnorePatterns in your Cocktail bootstrapper.
 
We'll take a look to see what we can do to fix this problem with over eager DevForce enum probing.

Ok I got this working for my silverlight but I am getting the same error in WPF. I added:

IdeaBlade.Core.Composition.CompositionHost.IgnorePatterns.Add("C5.*");


To my bootstrapper in the OnStartup method. But when I look at the log it is not removing the C5.dll from the list of items being probed.
Probe Assemblies: C5, Version=1.1.0.0, Culture=neutral, 
PublicKeyToken=06a1b38866503b69 :: Caliburn.Micro, Version=1.4.0.0, 
Culture=neutral,blah, blah blah
Am I putting the ignore patterns in the right place? Why isnt it working?

John,
OnStartup is too late. IgnorePatterns have to be set in a static ctor in the bootstrapper, so they are set before Cocktail accesses the CompositionHost.
