NLog GetCurrentClassLogger() NullReferenceException using StructureMap (Full Trust) - structuremap

Question

It seems like NLog can't use reflection for GetCurrentClassLogger(), even though my MVC 3 app is deployed in a Full Trust environment on IIS7. I'm using StructureMap 2.6.1 and the problem seems to appear sporadically between deploys. I can't figure out why, though I don't think StructureMap is causing it.
Bootstrapper class:
public static class Bootstrapper
{
public static void ConfigureStructureMap()
{
ObjectFactory.Initialize(Init);
}
private static void Init(IInitializationExpression x)
{
x.AddRegistry(new DBServiceRegistry());
x.AddRegistry(new MyRegistry());
}
}
Registry class:
public class MyRegistry : Registry
{
public MyRegistry()//HttpContext context)
{
For<ILogger>().Use<NLogLogger>();
For<IUserRepository>().Use<SqlUserRepository>();
}
}
Everything works great on my machine. Why am I getting a System.NullReferenceException: Object reference not set to an instance of an object error when deploying?

Turns out it's not a trust issue, but an IoC issue. Thanks to an NInject solution for steering me in the right direction.
Solution
For your logging wrapper, use a constructor that accepts a string parameter:
public class NLogLogger : ILogger
{
private Logger _logger;
public NLogLogger(string currentClassName)
{
_logger = LogManager.GetLogger(currentClassName);
}
...
}
NLog StructureMap Config:
For<ILogger>().Use<NLogLogger>()
.Ctor<string>("currentClassName")
.Is(x => x.BuildStack.Root.RequestedType.FullName);
