Exception After Obfuscation On Wpf Application

Hello,

We have Wpf application which distibuted clients by clickonce technology. We bought SmartAseemply product for obfuscation. At our first obfuscated releae some clients take an error on appliacation init.

After some research we found exception detailk at clients eventlog. Error was thrown at AssemblyLoad event. You can find eventlog detail below(Sorry its turkish bacause of language pack)

We subscribe AssemblyLoad event to prevent from third party injectors like Snoop. You can also find code below.

After some investigation on client machines we realize .Net 4.5 Turkish Langauge pack was installed at these computers. Our opinion, system couldn't load satellite assemblies after obfuscation and we still havent found a solition yet.

Any Opinion?

Thanks for help.

Code:

public App()
{
AppDomain.CurrentDomain.AssemblyLoad += new AssemblyLoadEventHandler(CurrentDomain_AssemblyLoad);
}

void CurrentDomain_AssemblyLoad(object sender, AssemblyLoadEventArgs args)
{

if (args.LoadedAssembly.FullName.StartsWith("ManagedInjector"))
{

Application.Current.Shutdown();
}

}

Eventlog :
