# MenuControllerBase

Extends `WebContextControllerBase` to additionally decorate the current view model with the session-cached Business Online menu, the current menu item, the controller's declared category, and whether the current user is external.

## Purpose
- Extends `WebContextControllerBase` to additionally decorate the current view model with the session-cached Business Online menu, the current menu item, the controller's declared category, and whether the current user is external.
- Every consuming application's controllers ultimately derive from this class to get menu rendering support.

## Context
- Namespace: `SAIF.Web.Mvc.Controllers`
- Assembly/package: `SAIF.Framework.Web.Mvc (source-shipping NuGet package)`
- Kind: abstract class

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| ApplicationUser | `protected IApplicationUserProfile ApplicationUser { get; }` | Lazily resolved and request-memoized current user, used to determine `IsExternalUser`. |
| UserProfileService | `public IUserProfileService UserProfileService { get; set; }` | Property-injected service used to resolve `ApplicationUser`. |
| MenuCategory | `protected abstract string MenuCategory { get; }` | Category code the derived controller must supply; used to filter `RenderTopMenu` output. |
| MenuControllerBase(IMenuService, IWebContextService, IUserProfileService) | `protected MenuControllerBase(IMenuService menuService, IWebContextService webContextService, IUserProfileService userProfileService)` | Constructor-injects the services this base class and its parent need. |
| OnActionExecuted(ActionExecutedContext) | `protected override void OnActionExecuted(ActionExecutedContext filterContext)` | Builds/reuses the cached menu and decorates the view model; see the "Build and attach the Business Online menu" operation. |
