In the sample code from Xamarin website, the Detail page was added to a NavigationPage

Detail = new NavigationPage(new TestPage());

Does TestPage have to be wrapped by NavigationPage? If I remove NavigationPage and just put new TestPage(), it will work on me. If I keep NavigationPage in, I have the error which I have posted in here.

Reference from my other post

If without NavigationPage, the hamburger icon will be gone, even though still able to show the master page.

From official Xamarin documentation:

Public Constructors

NavigationPage()
Initializes a new NavigationPage object.

NavigationPage(Page) 
Creates a new NavigationPage element with root as its root element.

So you only need/want/have to pass a page as argument if you want to specify that it's a root element.

Also in case you developing an UWP app with MasterDetailPage you should keep in mind:

Generally, you'll set these two properties to objects of type ContentPage, but currently, to get MasterDetailPage to work on the Universal Windows Platform, the detail page must be a NavigationPage.
