Use when adding RibbonControl, ToolBarControl, MainMenuControl, StatusBarControl, BarManager, or RibbonStatusBarControl to a WPF window; defining bar items (BarButtonItem, BarCheckItem, BarSplitButtonItem, BarSubItem, BarEditItem, BarStaticItem, BarItemSeparator) and bar item links; building Ribbon structure with RibbonPageCategory, RibbonPage, RibbonPageGroup; configuring Quick Access Toolbar, Application Menu, BackstageView, Ribbon Status Bar; using glyphs, ItemDisplayMode, RibbonStyle; merging child window bars/ribbons into the parent (MDI merging via DockLayoutManager). Also use when someone mentions "ThemedWindow", "WindowKind=Ribbon", "DevExpress.Xpf.Ribbon", "DevExpress.Xpf.Bars", "dxr:", "dxb:", "BarItem", or asks about Office-style UIs in WPF. Covers .NET 8+ and .NET Framework 4.6.2+.
Build WPF tabbed UIs with DevExpress DXTabControl — define tabs explicitly as DXTabItem children or generate them from a data collection via ItemsSource + ItemHeaderTemplate / ItemTemplate, pick one of three views (MultiLine, Scroll, Stretch) for how headers overflow, customize colors per tab (AccentColor/BorderColor), and template every region of the control (left/right control box, content header/footer, panel area). Use when building document tabs, settings panes, master-detail editors, or any tabbed-page UI in WPF. Also use when someone mentions "DXTabControl", "DXTabItem", "TabControlMultiLineView", "TabControlScrollView", "TabControlStretchView", "TabContentCacheMode", "AccentColor", "AllowHide", "Glyph", "PinMode", or "DragDropMode". The host window should be ThemedWindow (not Window) for proper visual integration. Covers .NET 8+ and .NET Framework 4.6.2+.

Build WPF applications with the DevExpress TreeList (TreeListControl) — a data-aware control for hierarchical data. Use when adding TreeListControl, binding to self-referential data (Key/Parent fields), hierarchical data (ChildNodesPath/Selector/DataTemplate), or building unbound trees with TreeListNode. Covers TreeListColumn, sorting, filtering, summaries, expand/collapse, drag-and-drop, multi-selection, edit forms, validation, conditional formatting, printing, exporting. Also use when someone mentions "DevExpress WPF tree", "TreeListControl", "TreeListView", "dxg:TreeListControl", "DevExpress.Xpf.Grid.TreeListControl", "self-referential tree", "KeyFieldName ParentFieldName", "unbound tree", or asks about org charts, file trees, project hierarchies, BOM, parent-child collections, or any tree UI in WPF. Covers both .NET 8+ and .NET Framework 4.6.2+.
XPO-specific CRUD and business logic patterns for XAF applications. Sub-skill of devexpress-xaf-business-logic — load this when XPO ORM is detected. Covers UnitOfWork, Session, XPCollection, XPQuery (LINQ to XPO), XPView, NestedUnitOfWork, XPObjectSpace.Session access, AfterConstruction/OnSaving/OnDeleting/OnLoaded overrides, SetPropertyValue, GetCollection, connection pooling, XPInstantFeedbackSource, XPServerCollectionSource. Use when someone mentions "UnitOfWork", "Session", "XPCollection", "XPQuery", "NestedUnitOfWork", "SetPropertyValue", "AfterConstruction", "Session.FindObject", or asks about XPO data operations in XAF.
Design XAF business model classes with EF Core or XPO. Use when creating persistent classes, defining entity relationships (one-to-many, many-to-many, aggregated), applying data annotations and XAF attributes, configuring DbContext, registering types in ModuleBase, supplying initial data in Updater, working with base persistent classes, configuring EF Core migrations, or mapping property types to built-in editors. Also use when someone mentions "XAF business class", "XAF data model", "BaseObject", "IXafEntityObject", "DefaultClassOptions", "XPO persistent object", "SetPropertyValue", "DbSet", "AdditionalExportedTypes", or asks about XAF entity design.
Implement XAF CRUD operations and business logic with IObjectSpace. Use when creating, reading, updating, or deleting objects, calling CommitChanges, handling ObjectSpace events (Committing, Committed, ObjectChanged, ObjectSaving), accessing ObjectSpace in controllers or business classes, using IXafEntityObject lifecycle hooks (OnCreated, OnLoaded, OnSaving), working with NonPersistentObjectSpace, creating Object Spaces via XafApplication.CreateObjectSpace, IObjectSpaceFactory, or INonSecuredObjectSpaceFactory. Also use when someone mentions "ObjectSpace", "CommitChanges", "CreateObject", "FindObject", "GetObjectsQuery", "IObjectSpaceLink", "ModuleUpdater", "Updater", or asks about XAF data manipulation. Covers EF Core and XPO (load the devexpress-xaf-business-logic-xpo sub-skill for XPO-specific patterns).
>- XAF editors covering Property Editors, List Editors, and View Items; data-type-to-editor mappings; accessing and customizing editor controls with CustomizeViewItemControl and OnViewControlsCreated; and implementing custom Property Editors, List Editors, and View Items for Blazor and WinForms.
