Why I am getting "Type reference cannot find type" exception while referring ResourceDictionary in C# code

I am using following code to Create a Style in Resource Dictionary:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:Chart="clr-namespace:TestApp.Controls.Chart">


<Style x:Key="DefaultLabelStyle" TargetType="{x:Type Chart:LabelStyle}">
    <Setter Property="LabelBrush">
        <Setter.Value>
            <SolidColorBrush Color="Red"/>
        </Setter.Value>
    </Setter>
    <Setter Property="LabelFontSize" Value="12.0"/>
    <Setter Property="Visibility" Value="False"/>
    <Setter Property="OrientationAngle" Value="0"/>
    <Setter Property="LabelPlacement" Value="Top"/>
    <Setter Property="LabelOrientation" Value="Normal"/>
</Style>

and then trying to consume it using following code:

 public static void LoadSkin()
    {
        var _skinDictionary = new ResourceDictionary { Source = new Uri("/Chart;component/Resources/DefaultSkin.xaml", UriKind.RelativeOrAbsolute) };
    }

but its throwing "Type reference cannot find type" exception, mentioning that unable to find LabelStyle. But LabelStyle is a public class in Chart.

What I am doing wrong here?

I tried checking other threads here with similar problem and tried to make those changes,

still it doesn't works :(

Please let me know your suggestions..!!

You cannot apply a Style to a type that is not derived from FrameworkElement or FrameworkContentElement. See the Remarks section in Style.TargetType.

Maybe your LabelStyle class could simply get its property values from resources like this:

<ResourceDictionary ...
    xmlns:sys="clr-namespace:System;assembly=mscorlib">
    <sys:Double x:Key="LabelFontSize">12.0</sys:Double>
    ...
</ResourceDictionary>
