Minimum size of a window

Question

I'm developing an UWP app and I would like to set a minimum window size (in desktop)

I've been looking and I do not know where this is done.

You can set some of 'Windows' properties in ApplicationView class. There is a method that allows to set the Minimum size of application window (desktop only) - SetPreferredMinSize. However, this accepts values only from certain range:

The smallest allowed minimum size is 192 x 48 effective pixels. The largest allowed minimum size is 500 x 500 effective pixels. If you set a value outside of these bounds, it is coerced to be within the allowed bounds.

To do what you want you will have to set it upon app launching:

ApplicationView.GetForCurrentView().SetPreferredMinSize(new Size(300, 300));

Note that you also can set a preferred launch size with other property:

ApplicationView.PreferredLaunchViewSize = new Size(600, 600);

One key thing to note Is that you are providing DIPS, not PIXELS, for this API. See this code for an example of usage.

@FernandoSousa You should put this in app.xaml.cs before activating the window.

It gives an error. This is my app.xaml.cs:

sealed partial class App : BootStrapper     {         public App()         {             InitializeComponent();             SplashFactory = (e) => new Views.Splash(e);         }          public override async Task OnStartAsync(StartKind startKind, IActivatedEventArgs args)         {             // TODO: add your long-running task here             await NavigationService.NavigateAsync(typeof(Views.MainPage));         }     }

@FernandoSousa You have provided too little code and no exception message and information. Besides, I don't see how this is connected to my answer and comments shouldn't be used to ask new questions.

This is my code, I do not know where to put this code: ApplicationView.GetForCurrentView().SetPreferredMinSize(new Size(300, 300));

As you can see here you can use minWidth and minHeight properties in the xaml.
