I'm working with a frustrating scenario with a custom user control in my WPF project using Visual Studio 2022. The control renders perfectly in the designer, but when I run the application, it appears completely blank. I've verified that the data context is correctly set, and I've even tried using a simple text block inside the control to test if anything is being displayed. Here's a simplified version of my user control: ```xml <UserControl x:Class="MyApp.Controls.MyCustomControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid> <TextBlock Text="Hello, World!" VerticalAlignment="Center" HorizontalAlignment="Center" /> </Grid> </UserControl> ``` And hereโ€™s how Iโ€™m using it in the main window: ```xml <Window x:Class="MyApp.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:controls="clr-namespace:MyApp.Controls" Title="MainWindow" Height="350" Width="525"> <Grid> <controls:MyCustomControl /> </Grid> </Window> ``` I've checked that the user control is properly defined in the XAML file, and the namespace is correctly referenced. Iโ€™ve also cleared the solution and rebuilt the entire project multiple times, but the control still doesnโ€™t display anything during runtime. The only time I see the control is in the designer view. Additionally, there are no exceptions or errors in the output window when I run the application, so Iโ€™m at a loss as to what could be causing this. Is there something specific I might be missing in regards to initialization or data context binding? Any insights would be greatly appreciated!
