I was following your example located here (Display military symbols with a dictionary renderer) in order to display Military Symbols based on the DictionaryRenderer. I get an error when attempting to Open the Symbol Style as follows:
SymbolStyle ss = await SymbolStyle.OpenAsync(@"D:\Source\MapEngine\ESRI\mil2525d.stylx");
DictionarySymbolStyle dss = ss as DictionarySymbolStyle;
The first line executes properly, but the second line fails ( assigns a null value) when assigning the SymbolStyle to the DictionaryStyle. I downloaded the styles from here: (http://solutions.arcgis.com/defense/help/military-symbology-styles/)
Am I missing something here? I am on 100.1 of the .NET SDK.
