Answer 1

The problem is because of incorrect order of your styles. I mean that if we publish button style with referrance on static resource NormalBrush, which is declared under the style, like this:

 <Style TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Background="{StaticResource NormalBrush}" >
                    <ContentPresenter Name="ButtonCont"></ContentPresenter>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>       
</Style>

<LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1">
    <GradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#FFF" Offset="0.0"/>
            <GradientStop Color="#CCC" Offset="1.0"/>
        </GradientStopCollection>
    </GradientBrush.GradientStops>
</LinearGradientBrush>

This code will give you such error. But if you change, like this

<LinearGradientBrush x:Key="NormalBrush" StartPoint="0,0" EndPoint="0,1">
    <GradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#FFF" Offset="0.0"/>
            <GradientStop Color="#CCC" Offset="1.0"/>
        </GradientStopCollection>
    </GradientBrush.GradientStops>
</LinearGradientBrush>

 <Style TargetType="{x:Type Button}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border Background="{StaticResource ButtonBackground}" >
                    <ContentPresenter Name="ButtonCont"></ContentPresenter>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>       
</Style>

Everything works fine. The same this occures if your resources are stored in different xaml files and you attach them in your ResourceDictionary. For example (cosider we store our NormalBrush in Colors.xaml and Button in Button.xaml). This gives error:

<ResourceDictionary Source="Resources\Button.xaml" />
<ResourceDictionary Source="Resources\Colors.xaml" />

This should work error:

<ResourceDictionary Source="Resources\Colors.xaml" />
<ResourceDictionary Source="Resources\Button.xaml" />

Answer 2

Please check if you have specified a converter in a Xaml that doesn't exist.

Answer 3

I had stumbled upon this exact problem. There is a problem with the XAML file. SolidBorderBrush is missing from the XAML. By adding it, the sample works fine.

<SolidColorBrush x:Key="SolidBorderBrush" Color="#000" />

Bellow follows the complete contents of the XAML file.
