[NonController]Subclassing.md

This doesn't work.

Base class:

/// <summary>
/// Handles the Administration Form API backend tasks
/// </summary>
[Route("api/LocalizationAdministration")]
[UnhandledApiExceptionFilter]    
[NonController]
public class LocalizationAdministrationController : Controller
{
    public LocalizationAdministrationController(IHostingEnvironment host, DbResourceConfiguration config)
    {
        Host = host;
        DbIRes = new DbResInstance(config);
    }

    [HttpGet]
    [Route("GetResourceList")]
    //public IEnumerable<ResourceIdItem> GetResourceList(string resourceSet)
    public ActionResult GetResourceList(string resourceSet)
    {
        var ids = Manager.GetAllResourceIds(resourceSet);
        if (ids == null)
            throw new ApplicationException(DbIRes.T("ResourceSetLoadingFailed", STR_RESOURCESET) + ":" +
                                           Manager.ErrorMessage);
        return Json(ids, jsonSettings);
    }

    ...
}

Subclassed:

[Controller]
public class LocalizationAdminController : LocalizationAdministrationController
{
    public LocalizationAdminController(IHostingEnvironment host, DbResourceConfiguration config) : base(host, config)
    {

    }
    public override void OnActionExecuting(ActionExecutingContext context)
    {
        base.OnActionExecuting(context);
        Debug.WriteLine("executing subclassed controller");
    }
}

the subclassed controller never fires and client gets a 404.

AbstractBaseClassWorks.md

This works with an abstract class:

Base class:

/// <summary>
/// Handles the Administration Form API backend tasks
/// </summary>
[Route("api/LocalizationAdministration")]
[UnhandledApiExceptionFilter]    
public abstract class LocalizationAdministrationController : Controller
{
    public LocalizationAdministrationController(IHostingEnvironment host, DbResourceConfiguration config)
    {
        Host = host;
        DbIRes = new DbResInstance(config);
    }

    [HttpGet]
    [Route("GetResourceList")]
    //public IEnumerable<ResourceIdItem> GetResourceList(string resourceSet)
    public ActionResult GetResourceList(string resourceSet)
    {
        var ids = Manager.GetAllResourceIds(resourceSet);
        if (ids == null)
            throw new ApplicationException(DbIRes.T("ResourceSetLoadingFailed", STR_RESOURCESET) + ":" +
                                           Manager.ErrorMessage);
        return Json(ids, jsonSettings);
    }

    ...
}

Subclassed:

// [Authorize]
[Controller]
public class LocalizationAdminController : LocalizationAdministrationController
{
    public LocalizationAdminController(IHostingEnvironment host, DbResourceConfiguration config) : base(host, config)
    {
    }
    
    public override void OnActionExecuting(ActionExecutingContext context)
    {
        base.OnActionExecuting(context);
        Debug.WriteLine("executing subclassed controller");
    }
}

This allows the user to manage the controller themselves with an [Authorized] attribute or whatever logic they want to add. It also allows overriding of behavior which is nice.
