DI and InstanceContextMode.Single

[chrc2]

Using the WcftQuickStart example, i get the following error when i change the instanceContextMode to Single(ton). Is there another way of starting up the DI container?

Error creating context 'spring.root': root context is currently in creation. You must not call ContextRegistry.GetContext() from e.g. constructors of your singleton objects

Hi,

thanks for reporting this.
We are investigating, and try to fix it for the WCF release.

Looks like there is the same pb with Oran Dennison approach (http://orand.blogspot.com/2006/10/wcf-service-dependency-injection.html).


A solution is to comment the ServiceExporter definition in the configuration file and use the programmatic way :
See Program.cs file in the Spring.WcfQuickStart.ServerApp console project :

// Programmatically (You need to comment 'ServiceExporter' object definition in App.config)
using (ServiceHost serviceHost = new ServiceHost("calculator"))
{
serviceHost.Open();

Console.Out.WriteLine("Server listening...");
Console.Out.WriteLine("--- Press <return> to quit ---");
Console.ReadLine();
}


The problem is that ServiceExporter also start a ServiceHost, and it should not.
