As of 2024 Q4 (November), we will deprecate the .NET 7 distribution. This decision is rooted in our dedication to align with Microsoft’s recommended framework versions so that our products leverage the latest advancements in technology, security, and performance.  

We are aligning our product with Microsoft’s lowest-supported framework versions for .NET Framework and .NET, respectively. Please refer to the following blog post: Product Update for Enhanced Performance and Security

For more information about how to upgrade your project when a new version of the Telerik UI for WPF suite is released, you can check here: Project Migration to .NET 4.6.2 and .NET 6

As of 2024 Q2, we will deprecate .NET Framework 4.0, .NET Framework 4.5, and .NET Core 3.1 distributions. This decision is rooted in our dedication to align with Microsoft’s recommended framework versions so that our products leverage the latest advancements in technology, security, and performance.

Can RadGlyph work with Font Awesome's Duotone font? For example, we want to render: https://fontawesome.com/icons/house?f=duotone&s=solid

I've tried various things, including:

                <Grid>
                    <!-- Secondary (back) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#x10F015;"
                        Foreground="Red" />
                    <!-- Primary (front) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#xF015;"
                        Foreground="Blue" />
                </Grid>

This just renders an all blue house.

Reversing the elements:

            <telerik:RadTabItem.Content>
                <Grid>
                    <!-- Primary (front) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#xF015;"
                        Foreground="Blue" />
                    <!-- Secondary (back) layer -->
                    <telerik:RadGlyph
                        Font="fads"
                        FontSize="40"
                        Glyph="&#x10F015;"
                        Foreground="Red" />
                </Grid>

I'm using the same technique I use to register regular Font Awesome fonts and have verified the codepoints exist:

        var solidDuotoneFontFilePath = Path.Combine(directory, "Resources/Fonts", "Font Awesome 7 Duotone-Solid-900.otf");
        var solidDuotoneFontUri = new Uri(solidDuotoneFontFilePath, UriKind.Absolute);
        var solidDuotoneFontFamily = new FontFamily(solidDuotoneFontUri, "./#Font Awesome 7 Duotone Solid");
        RadGlyph.RegisterFont(solidDuotoneFontFamily, "fads");

        bool HasChar(FontFamily fam, int codePoint)
        {
            var tf = new Typeface(fam, FontStyles.Normal, FontWeights.Normal, FontStretches.Normal);
            if (!tf.TryGetGlyphTypeface(out var gtf)) return false;
            return gtf.CharacterToGlyphMap.ContainsKey(codePoint);
        }

        Debug.WriteLine($"Primary F015 present: {HasChar(solidDuotoneFontFamily, 0xF015)}");
        Debug.WriteLine($"Secondary 10F015 present: {HasChar(solidDuotoneFontFamily, 0x10F015)}");

I am using the Material Theme, here's my app.xaml code

<Application x:Class="Desktop_Application.App"

        <ResourceDictionary>
            <!-- Global default font size -->
            <Style TargetType="{x:Type Control}">
                <Setter Property="FontSize" Value="8"/>
            </Style>
            
            <ResourceDictionary.MergedDictionaries>

                <ResourceDictionary Source="/Telerik.Windows.Themes.Material;component/Themes/Telerik.Windows.Controls.Chart.xaml"/>

I'm using central package management, where my Directory.Build.props has folliwing entries:

<ItemGroup>
    <PackageVersion Include="Telerik.UI.for.Wpf.NetCore.Xaml" Version="2024.1.423" />
    <PackageVersion Include="Telerik.Windows.Controls.Data.for.Wpf.Xaml" Version="2025.2.707" />
    <PackageVersion Include="Telerik.Windows.Controls.DataVisualization.for.Wpf.Xaml" Version="2024.3.924" />
    <PackageVersion Include="Telerik.Windows.Controls.Diagrams.Extensions.for.Wpf.Xaml" Version="2025.2.707" />
    <PackageVersion Include="Telerik.Windows.Controls.Diagrams.for.Wpf.Xaml" Version="2025.2.707" />
    <PackageVersion Include="Telerik.Windows.Controls.Diagrams.Ribbon.for.Wpf.Xaml" Version="2025.2.707" />
    <PackageVersion Include="Telerik.Windows.Controls.for.Wpf.Xaml" Version="2025.2.707" />

    <PackageVersion Include="Telerik.Windows.Diagrams.Core.for.Wpf.Xaml" Version="2025.2.707" />
</ItemGroup>

As you can maybe see, 

Telerik.UI.for.Wpf.NetCore.Xaml has 2024.1.423
Telerik.Windows.Controls.DataVisualization.for.Wpf has 2024.3.924

when using the manage nuget packages dialog from within visual studio it does not report that any updates are necessary, but the build tells me that (of course) there is a version mismatch,

The dialog even tells me that there is a newer version:

What could be the problem that it doesn't get updated or is not found to require an update?

Hi Team,

We have developer license for the Telerik UI for WPF product, however we are unable to get the developer MSI for the Telerik UI for WPF 2024.1.130.45. Only the trial version is visible now.

Could you please guide us to get the dev  version of 2024.1.130.45?
