System.NotImplementedException: "The method or operation is not implemented." when using the extension library

I am using the extension library to inject httpapi, but System.NotImplementedException: "The method or operation is not implemented."

System.Reflection.TargetInvocationException

You need to provide a sample reproduction of the issue you're facing. I'm guessing most likely that the issue is that you're trying to use Prism.Unity.Forms and Prism.Unity.Extensions and not Prism.Forms.Extended which means you never get the container instance that has the extensions implemented.
