Microsoft-ui-xaml: Proposal: Window Width/Height in Desktop

Proposal: Support Window Width/Height when in Desktop

Summary

For WinUI in Desktop apps:

• Support setting Width and Height on Window in XAML.
• Support setting d:DesignWidth and d:DesignHeight on Window in XAML.

<Window Width="1200" Height="600"
        d:DesignWidth="1000" d:DesignHeight="500">

Rationale

Many developers doing WinUI in Desktop will have a background in WPF and/or simply not be interested in doing a responsive design -- this is "in Desktop" after all. Without the ability to set Window size in a traditional way, I believe adoption will suffer due to too much forced change.

@JVimes, thanks for opening this request. I believe there should be APIs that allow developers to do this. The APIs should work for both, UWP and Desktop.

@marb2000 It appears not:

I'm wondering if there is any API to manage window size/position at all?

[marb2000]

While these APIs doesn't exist in Desktop WinUI 3 apps, I published a sample to workaround it using the Win32 APIs.

Using the SetWindowPos API you can set the size and/or the position of a Window object.

Thanks for the workaround, @marb2000. The code also looks like a starting point to address the problem.
