Set main window size for Windows desktop target

[wgraaf]

How can the size of the main window be set when targeting the windows (10) desktop?
The main window starts out way too big, and I have to manually resize every time may app is launched.

Thanks for the question. It would be best to ask it in the WinUI or WinAppSDK repositories.

Make sure you only execute this on Windows.

	private void ConfigureViewSize()
	{
		var windowHandle = WinRT.Interop.WindowNative.GetWindowHandle(CurrentWindow);
		var windowId = Microsoft.UI.Win32Interop.GetWindowIdFromWindow(windowHandle);
		var appWindow = Microsoft.UI.Windowing.AppWindow.GetFromWindowId(windowId);
		appWindow.Resize(new Windows.Graphics.SizeInt32 { Width = 480, Height = 800 });
	}

Where does that Win32Interop comes from? It's not in Uno

As long as you have the Window instance, you can just do window.AppWindow.Resize

Trying Uno for desktop platform.
Created a new project using blank template.
I added the suggested code at the end of "OnLaunched" in the App.cs file.
Added
using Microsoft.UI;
using Microsoft.UI.Windowing;

but I still get:
Error CS0234 The type or namespace name 'Win32Interop' does not exist in the namespace 'Microsoft.UI' (are you missing an assembly reference?)

I installed the "Windows App SDK" to get WinUI 3
What Am I doing wrong ?

Are you using WinUI or UWP?

[wirelessfrank]

I understand I should be using WinUI 3 but there is no choice specific choice in the
Select startup type.
I tried Blank
Customized to

1. Framework=> .NET 7.0
2. Platforms => Only Windows
3. Presentation => None
4. Theme => Fluent
5. Extensions => None
6. Projects => None
7. Features => Central Package Management & Visual Studio Code Debugging
8. Authentication => None
9. Application =>com.companyname.UnoApp1
10. Testing => None

I go to the Apps.cs file and get the result above.
