Exception: Object of type 'Csla.Rules.AddObjectAuthorizationRulesContext' cannot be converted to type 'Csla.ApplicationContext'.

CSLA 8 get the error message when calling HasPermission. Here's the HasPermissioin method being called in CSLA:

//
// Summary:
// Checks per-type authorization rules.
//
// Parameters:
// applicationContext:
//
// action:
// Authorization action.
//
// objectType:
// Type of business object.
public static bool HasPermission(ApplicationContext applicationContext, AuthorizationActions action, Type objectType)
{
if (applicationContext == null)
{
throw new ArgumentNullException("applicationContext");
}

Here's the calling function from the business object:

public static bool CanGetObject(ApplicationContext appContext)
{
return Csla.Rules.BusinessRules.HasPermission(appContext, Csla.Rules.AuthorizationActions.GetObject, typeof(AddressAddressTypeList));
}

The method signatures match and ApplicationContext is valid. What could be happening to get the exception:

Object of type 'Csla.Rules.AddObjectAuthorizationRulesContext' cannot be converted to type 'Csla.ApplicationContext'.

Call Stack only shows what I've posted. Help! :-)

Hi. A mwe works correctly. Here's the code I'm using:

using Csla;
using Csla.Configuration;
using Csla.Rules;
using Csla.Rules.CommonRules;
using Microsoft.Extensions.DependencyInjection;

using var sp = new ServiceCollection()
    .AddCsla()
    .BuildServiceProvider();

var appContext = sp.GetRequiredService<ApplicationContext>();
Console.WriteLine(Csla.Rules.BusinessRules.HasPermission(appContext, AuthorizationActions.GetObject, typeof(TestList)));

[Serializable]
public class TestList : BusinessListBase<TestList, Test>
{
    [ObjectAuthorizationRules]
    public static void AddObjectAuthorization()
    {
        BusinessRules.AddRule(typeof(TestList), new IsInRole(AuthorizationActions.GetObject, "Krznbf"));
    }
}

[Serializable]
public class Test : BusinessBase<Test>;

I've added CSLA 8.2.9 and the HasPermission line works as expected - returning false.

Can you give more information about the calling code and AddressAddressTypeList?
