style is not applied at runtime but being applied at design time

Hi There,

I have a simple style in a resource dictionary which is located in a WPFResources.dll, i am accessing this style in another project, i can see that the style is being applied at design time, but when i run the application i am geeing an exception that "Cannot find resource named 'IndentCheckBoxStyle'. Resource names are case sensitive". if i use the StaticResource then i can see this exception if i use the DynamicResource then i dont see any exception, but nothing is visible on the UI.

Any one have any idea about this ??

Thanks in advance.
