I have a brush that is part of a ResourceDictionary that is merged to Application.
Resources.
But for some reason it's not resolved at runtime when a style is being applied to one of the controls. However, if I call Application.Current.FindResource("BrushName") from the Immediate Window at the time when exception is thrown, the resource is found.
Am I missing something? Isn't WPF supposed to try to look for the resource in the app's resources?
UPDATE
The application is quite big, so I can't post all actual code but here's the way the
resources are merged and used:
Brushes.xaml
<ResourceDictionary ...>
<SolidColorBrush x:Key="BrushName" Color="#12345678" />
<\ResourceDictionary>
SomeStyles.xaml
<ResourceDictionary ...>
<Style x:Key="SomeStyle">
<Setter Property="SomeProperty" Value="{StaticResource BrushName}" />
</Style>
</ResourceDictionary>
App.xaml
<Application ...>
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Brushes.xaml" />
<ResourceDictionary Source="SomeStyles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application ...>
And then some control might use the style using the resource like this:
...
Style={StaticResource SomeStyle}
...
