You can use Command...

<ui:ContentDialog x:Class="ModernWPFUITest.TestContentDialog"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:ModernWPFUITest"
             mc:Ignorable="d" 
             IsPrimaryButtonEnabled="False"
             PrimaryButtonText="OK"     
             DefaultButton="Primary"
             xmlns:ui="http://schemas.modernwpf.com/2019">
    <Grid>
            
    </Grid>
</ui:ContentDialog>

Show ContentDialog above, hit enter key then ContentDialog will close.

Create a custom command and set CanExecute

Thank you for your comment.

UWP's ContentDialog does not accept Enter key with the code above.

This behavior is not safe for users. I hope this pullrequest is merged.

             PrimaryButtonText="OK"    
             SecondaryButtonText="Cancel"
             DefaultButton="Primary"

        <TextBox />
    </Grid>
</ui:ContentDialog>

In this case, hit Enter key then result is Primary.

How about catching KeyDown event and use this.Hide();?

Guys I use this workaround to deal with ESC, Enter key when dialog closing.

public partial class XXXDialog : ContentDialog
{
    public XXXDialog()
    {
            InitializeComponent();

            PrimaryButtonClick += (_, _) =>
            {
                // Condition here cause "Enter" key would cross this
                if (IsPrimaryButtonEnabled)
                {
                    ;
                }
            };

            Closing += (_, args) =>
            {
                // If the PrimaryButton is disabled, block the "Enter" key
                if (args.Result == ContentDialogResult.Primary && !IsPrimaryButtonEnabled)
                {
                    args.Cancel = true;
                }
            };
    }
}
