Hi, I'm trying to use the DatabaseFactory.CreateDatabase() method, but I keep getting an exception:

VB Code:
  1. at Microsoft.Practices.EnterpriseLibrary.Data.DatabaseConfigurationView.get_DefaultName()

  2.    at Microsoft.Practices.EnterpriseLibrary.Data.DatabaseMapper.MapName(String name, IConfigurationSource configSource)

  3.    at Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.ConfigurationNameMappingStrategy.BuildUp(IBuilderContext context, Type t, Object existing, String id)

  4.    at Microsoft.Practices.ObjectBuilder.BuilderBase`1.DoBuildUp(IReadWriteLocator locator, Type typeToBuild, String idToBuild, Object existing, PolicyList[] transientPolicies)

  5.    at Microsoft.Practices.ObjectBuilder.BuilderBase`1.BuildUp(IReadWriteLocator locator, Type typeToBuild, String idToBuild, Object existing, PolicyList[] transientPolicies)

  6.    at Microsoft.Practices.ObjectBuilder.BuilderBase`1.BuildUp[TTypeToBuild](IReadWriteLocator locator, String idToBuild, Object existing, PolicyList[] transientPolicies)

  7.    at Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.EnterpriseLibraryFactory.BuildUp[T](IReadWriteLocator locator, IConfigurationSource configurationSource)

  8.    at Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.EnterpriseLibraryFactory.BuildUp[T](IConfigurationSource configurationSource)

  9.    at Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.NameTypeFactoryBase`1.CreateDefault()

  10.    at Microsoft.Practices.EnterpriseLibrary.Data.DatabaseFactory.CreateDatabase()

  11.    at DAL.Controller.Country_Add(String name, String code) in ...\Controller.cs:line 83

This is my app.config, and I'm pretty sure it is correct:

Code:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<configSections>
		<section 
			name="dataConfiguration"
			type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null"/>
	</configSections>
	<dataConfiguration 
		defaultDatabase="mydb" />
	<connectionStrings>
		<add 
			name="mydb"
			connectionString="Data Source=(local);Initial Catalog=mydb;Integrated Security=True;"
			providerName="System.Data.SqlClient" />
	</connectionStrings>
</configuration>
Any ideas on what the problem might be?
