ValueFactory attempted to access the Value property of this instance

See original GitHub issue

.NET 5.0 | Prism.Wpf 8.0.0.1909

While overriding the CreateContainerExtension() method in App.xaml.cs, I get the following error ValueFactory attempted to access the Value property of this instance.

Code:

        protected override IContainerExtension CreateContainerExtension()
        {
            return ContainerLocator.Current;
        }

Trace:

System.InvalidOperationException
  HResult=0x80131509
  Message=ValueFactory attempted to access the Value property of this instance.
  Source=System.Private.CoreLib
  StackTrace:

   at System.Lazy`1.get_Value()
   at Prism.Ioc.ContainerLocator.get_Current()
   at System.Lazy`1.ViaFactory(LazyThreadSafetyMode mode)

  This exception was originally thrown at this call stack:
    [External Code]
    Fss.Searcher.App.CreateContainerExtension() in App.xaml.cs

You should be calling PrismContainerExtension.Init()
