Calcium SDK: Replace IShell Implementation

When using the Calcium SDK[^] to replace the shell implementation entirely with your own implementation, use:

void Application_Startup(object sender, StartupEventArgs e)
{
  var container = new UnityContainer();
  ServiceLocatorSingleton.Instance.InitializeServiceLocator(container);
  var shell = new YourCustomShell();
  container.RegisterInstance<IShell>(shell);
}

Or in VB:

Sub Application_Startup(sender As Object, e As StartupEventArgs)
	Dim container As var = New UnityContainer()
	ServiceLocatorSingleton.Instance.InitializeServiceLocator(container)
	Dim shell As var = New RonsShell()
	container.RegisterInstance(Of IShell)(shell)
End Sub
