❔ XAML Designer WPF

im new to c# and programming. im using visual studio to make wpf program where you guess a number. im using chatgpt to tell me how to do this. it says double click the MainWindow.xaml to open the XAML designer. i did that but i dont think it opened? because theres no toolbox where i can select text box, button, label etc. and those are what i want to create. what do i do?

Your first mistake Also, don't use the designer Just edit the XAML file and type in your controls $rulesofwpf

Rules of WPF:

❌ Avoid the WPF Designer to eliminate a category of confusing bugs
❌ Don't rely on Margin as the primary tool for layouts
❌ Avoid writing UserControls or subclassing to extend a default control -- use Behaviors instead (Microsoft.Xaml.Behaviors.Wpf)

✅ Write XAML by hand and autoformat with "Ctrl K,D" or XAML Styler
✅ Rely upon XAML Hot Reload to design your app's UI at runtime
✅ Use layout controls (Grid, DockPanel, etc) to support proper resizing
✅ Use data binding to eliminate glue code and state synchronization issues
✅ Use collection controls and DataTemplate to dynamically create lists of controls
✅ Learn MVVM to create maintainable apps
✅ Use the Dispatcher to update controls from non-UI threads
✅ WPF's default controls can be easily modernized via $wpfuilibs
✅ Include relevant XAML, code-behind, and ViewModel code for questions when possible

Why do we avoid subclassing default controls?

¯\_(ツ)_/¯ Wasn't me who made this tag

The Associate role

Owns the 'rulesofwpf' tag.

Use tags inline with "$name"

Ask @Insire . But mostly because behaviors are better: composable, doesn't require styling changes, etc.

Insire•3y ago

because no styling library will work with subclassesed controls out of the box also, subclassed controls do not support sharing their functionality, behaviors and attached properties are the way to go for that
