Customizing Quick Info styles

Hello,

This is effectively the Style you can add to your Application.Resources and modify per your needs:

<Style TargetType="{x:Type editor:IntelliPromptQuickInfo}">
	<Setter Property="Background" Value="{DynamicResource {x:Static themes:AssetResourceKeys.ToolTipBackgroundNormalBrushKey}}" />
	<Setter Property="BorderBrush" Value="{DynamicResource {x:Static themes:AssetResourceKeys.ToolTipBorderNormalBrushKey}}" />
	<Setter Property="BorderThickness" Value="{DynamicResource {x:Static themes:AssetResourceKeys.ToolTipBorderNormalThicknessKey}}" />
	<Setter Property="Foreground" Value="{DynamicResource {x:Static themes:AssetResourceKeys.ToolTipForegroundNormalBrushKey}}" />
		
	<Setter Property="FontSize" Value="12" />
	<Setter Property="Padding" Value="{DynamicResource {x:Static themes:AssetResourceKeys.ToolTipPaddingNormalThicknessKey}}" />

	<Setter Property="themes:ThemeProperties.CornerRadius" Value="{DynamicResource {x:Static themes:AssetResourceKeys.ToolTipBorderNormalCornerRadiusKey}}" />
		
	<Setter Property="Template">
		<Setter.Value>
			<ControlTemplate TargetType="{x:Type editor:IntelliPromptQuickInfo}">

				<Border Background="{TemplateBinding Background}"
						BorderBrush="{TemplateBinding BorderBrush}"
						BorderThickness="{TemplateBinding BorderThickness}"
						Padding="{TemplateBinding Padding}"
						CornerRadius="{TemplateBinding themes:ThemeProperties.CornerRadius}"
						SnapsToDevicePixels="True">

					<shared:PixelSnapper>
						<ContentPresenter Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Session.Content}" />
					</shared:PixelSnapper>

				</Border>

			</ControlTemplate>
		</Setter.Value>
	</Setter>
</Style>

Thank you for your help!
