How to dynamically/programmatically set the Enterprise Library Database Trace Listener connect string

Question

Is there a way to dynamically/programmatically set the connection string the EntLib 5 database trace listener utilizes?

I am hosting my WCF service in Windows Azure, which means I will not have access to the web.config once it is deployed. In order to eliminate the need to redeploy my solution whenever I want to point the DB trace listener at a different DB I was hoping there would be a way I could pull that setting from my service configuration file and set it dynamically.

Yes, you can use the fluent configuration as described in this post:

var builder = new ConfigurationSourceBuilder();
builder.ConfigureData()
        .ForDatabaseNamed("MyDb")
        .ThatIs.ASqlDatabase()
        .WithConnectionString(RoleEnvironment.GetConfigurationSettingValue("MyConnectionString"))
        .AsDefault();

builder.ConfigureLogging()
        .WithOptions
        .LogToCategoryNamed("General")
        .SendTo
        .Database("Formatted Database TraceListener").UseDatabase("MyDb")
        ...;

var configSource = new DictionaryConfigurationSource();
builder.UpdateConfigurationWithReplace(configSource);
EnterpriseLibraryContainer.Current = EnterpriseLibraryContainer.CreateDefaultContainer(configSource);
