visual-studio wpf hot-reload xaml C#

I'm a bit lost with This might be a silly question, but I'm running Visual Studio 2022 Version 17.4 and I've been trying to use Hot Reload for my WPF application to see changes in XAML files without needing to restart the application. However, it seems that changes I make in the XAML files do not reflect in the running application. For instance, I added a new `Button` control to my `MainWindow.xaml` like this: ```xml <Button Content="Click Me!" Width="100" Height="30" /> ``` After saving the changes, I expect to see the button appear immediately in the running application, but nothing happens. I've checked the Hot Reload settings and both "Enable Hot Reload" and "Enable Hot Reload for XAML" are checked. I also tried cleaning and rebuilding the solution, and even restarted Visual Studio, but the scenario continues. Moreover, when I check the Output window while running the app, I see the following message: ``` Hot Reload: XAML changes not applied. Ensure your project is in Debug mode. ``` My project is indeed set to Debug configuration. The solution consists of a few projects, including a Class Library for my view models. Could this be affecting Hot Reload? Is there something specific I might be missing here? Any help would be appreciated! My development environment is macOS. Any help would be greatly appreciated! I'm using C# stable in this project. What's the best practice here?
