Font Family and Font Size
When using the VisualStudio2019 theme you can dynamically change the FontSize and FontFamily properties of all components in the application the same way as you do in Windows8, Windows8Touch, Office2013, VisualStudio2013, Office2016, Green, Material, Fluent and Crystal themes.
The FontSize and FontFamily properties are public so you can easily modify the theme resources at a single point. The most commonly used font size in the theme is with value 12 and can be modified through the VisualStudio2019Palette.Palette.FontSize property in the same manner as in the other themes that support a theme palette.
The default font used in the theme is Segoe UI.
For complex scenarios we strongly recommend setting the FontSize properties only before the application is initialized.
Example 1 shows the default font sizes and families.
Example 1: Default FontSize
VisualStudio2019Palette.Palette.FontSizeXS = 10;
VisualStudio2019Palette.Palette.FontSizeS = 11;
VisualStudio2019Palette.Palette.FontSize = 12;
VisualStudio2019Palette.Palette.FontSizeL = 13;
VisualStudio2019Palette.Palette.FontSizeXL = 20;
Example 2: Changing the theme's FontSize and FontFamily
private void OnButtonChangeFontSizeClick(object sender, RoutedEventArgs e)
{
VisualStudio2019Palette.Palette.FontSize = 16;
VisualStudio2019Palette.Palette.FontFamily = new FontFamily("Calibri Italic");
}

Glyphs
The VisualStudio2019 Theme also uses the Telerik Web UI font glyphs by default. The RadGlyph provides a lightweight, flexible and design-time-friendly implementation of our glyph font.
You can read more about the RadGlyph in the RadGlyph Overview article and about the range of the font glyphs in the Font Glyphs Overview article.
Theme Helper
The ThemeHelper class that comes with the R3 2019 release is used in the VisualStudio2019 theme. It exposes a set of attached properties and can be used to directly modify the appearance of a specific basic control without the need to alter its control template.
Example 3 shows a RadToggleButton control with modified brushes for its different states through the ThemeHelper class:
Example 3: Set RadToggleButton's visual appearance through the ThemeHelper class
<telerik:RadToggleButton Content="RadButton"
Margin="10"
xmlns:helpers="clr-namespace:Telerik.Windows.Controls.Theming.Helpers;assembly=Telerik.Windows.Controls"
helpers:ThemeHelper.MouseOverBrush="{telerik:VisualStudio2019Resource ResourceKey=AccentMouseOverBrush}"
helpers:ThemeHelper.PressedBrush="{telerik:VisualStudio2019Resource ResourceKey=ValidationBrush}"
helpers:ThemeHelper.CheckedBrush="{telerik:VisualStudio2019Resource ResourceKey=AccentMainBrush}"/>

Changing Opacity
If you need to change the opacity of the disabled and read-only elements, you can easily do so by using the DisabledOpacity and ReadOnlyOpacity properties of the VisualStudio2019Palette. The default values are 0.3 and 0.6 respectively.
Example 4: Changing the opacity
VisualStudio2019Palette.Palette.DisabledOpacity = 0.5;
VisualStudio2019Palette.Palette.ReadOnlyOpacity = 0.5;
VisualStudio2019Palette.Palette.DisabledOpacity = 0.5
VisualStudio2019Palette.Palette.ReadOnlyOpacity = 0.5
