 static void ReplaceMapping(Microsoft::Maui::ICommandMapper<Microsoft::Maui::IElement ^, Microsoft::Maui::IElementHandler ^> ^ commandMapper, System::String ^ key, Action<TViewHandler, TVirtualView, System::Object ^> ^ method);

public static void ReplaceMapping<TVirtualView,TViewHandler> (this Microsoft.Maui.ICommandMapper<Microsoft.Maui.IElement,Microsoft.Maui.IElementHandler> commandMapper, string key, Action<TViewHandler,TVirtualView,object?> method) where TVirtualView : Microsoft.Maui.IElement where TViewHandler : Microsoft.Maui.IElementHandler;

static member ReplaceMapping : Microsoft.Maui.ICommandMapper<Microsoft.Maui.IElement, Microsoft.Maui.IElementHandler> * string * Action<'ViewHandler, 'VirtualView, obj (requires 'ViewHandler :> Microsoft.Maui.IElementHandler and 'VirtualView :> Microsoft.Maui.IElement)> -> unit (requires 'VirtualView :> Microsoft.Maui.IElement and 'ViewHandler :> Microsoft.Maui.IElementHandler)
