Trying to use Prism 8, ContainerLocator, IHttpClientFactory and Platform-Specific Service registration with DryIoc Extensions (not Magician) in a Xamarin Forms application
I have these nuget packages installed
Prism.DryIoc.Extensions
Prism.Forms
My main Xamarin Application inherits from PrismApplicationBase.
In platform code (eg Android) I have IPlatformInitializer implented by MainActivity and for platform-specific services I use:
LoadApplication(new App(this));
as documented here: https://prismlibrary.com/docs/dependency-injection/platform-specific-services.html
This line causes the IContainerExtension to be resolved in the shared code
protected override IContainerExtension CreateContainerExtension()
...but I can't find a way to successfully return a valid IContainerExtension implementation.
I've attempted:
https://prismlibrary.com/docs/dependency-injection/container-locator.html
var createContainerExtension = () => new DryIocContainerExtension();
ContainerLocator.SetContainerExtension(createContainerExtension);
But the code given here can't even compile - the DryIocContainerExtension class created is defined INTERNAL and isn't available to my application code.
If I use...
PrismContainerExtension.Init();
or
return ContainerLocator.Current;
...as worked previously (eg Prism 7.2) I get a runtime error as described here: https://githubmemory.com/repo/dansiegel/Prism.Container.Extensions/issues/180
ValueFactory attempted to access the Value property of this instance.
Please can someone advise what I'm doing wrong, or do I have to get my company to pay for Magician to resolve my issue?
