Error en plugin luego de actualizar versión de Evolution

Evolution 1.11.0.2
SQL Server

Instalé un desarrollo de plugin en un proyecto de Evolution con version 1.10.1.0, pero ahora que he actualizado su versión a 1.11.0.2, los formularios asociados a dicho desarrollo me arrojan el siguiente error al dar clic al botón Guardar:

System.MissingMethodExceptionMethod not found: 'Microsoft.Practices.EnterpriseLibrary.Validation.ValidationResults Aseinfo.Infrastructure.Base.Entity.IEntityService`2.get_ValidationResults()'.

¿A qué podría deberse este error? ¿Cómo podría resolverlo?

Nota: Ya apliqué el Anexo Hotfix 1.11.0.2

El texto de error registrado en el Elmah es como sigue:

System.MissingMethodException: Method not found: 'Microsoft.Practices.EnterpriseLibrary.Validation.ValidationResults Aseinfo.Infrastructure.Base.Entity.IEntityService`2.get_ValidationResults()'.
