IDataPortalFactory DI error - tweak to make it work gives a clue

[swegele]

Using your latest preview from Nuget...when I try to use the IDataPortalFactory in my business class factory like so:

public class BetaInfoListFactory : DemoReadOnlyListBaseFactory<BetaInfoList, BetaInfo>, IBusinessObjectListFactory
{
    public BetaInfoListFactory(IDataPortalFactory portal, ApplicationContext applicationContext)
    {
        Portal = portal.GetPortal<BetaInfoList>();

I get this error:
System.InvalidOperationException: A suitable constructor for type 'Csla.IDataPortal`1[BusinessLayer.BetaInfoList]' could not be located. Ensure the type is concrete and all parameters of a public constructor are either registered as services or passed as arguments. Also ensure no extraneous arguments are provided.

Based on some SO answers...I changed this (line 388) in your ApplicationContext.cs:

result = ActivatorUtilities.CreateInstance(CurrentServiceProvider, objectType, parameters);

to be this:

result = CurrentServiceProvider.GetService(objectType);

Then it works. Figured I would share with you my findings.

EDIT:

@rockfordlhotka Confirmed I get the same error in your BlazorExample, by changing as follows:

@inject Csla.IDataPortalFactory portalFactory

and below OnParametersSetAsync() to this:

var personListPortal = portalFactory.GetPortal<PersonList>();
await vm.RefreshAsync(() => personListPortal.FetchAsync());

Your latest PR fixes this :-)
