How to Debug Security Permission inside Sandbox solution

Question

I have created new AppDomain for Sandbox solution with following permissions:

        EvidenceBase[] hostEvidence = { new Zone(SecurityZone.Trusted) };
        Evidence evidence = new Evidence(hostEvidence, null);
        PermissionSet permissions = SecurityManager.GetStandardSandbox(evidence);

Third Party Plugin is loaded successfully how ever some calls return SecurityException and I cant figured out from StackTrace what resources are required that triggers this exception.

How can I get more details from SecurityException?

Code for creating child domain:

    AppDomain newDomain = AppDomain.CreateDomain("MySandBox", null, adSetup, permissions, fullTrustAssembly);
        ObjectHandle handle = Activator.CreateInstanceFrom(
            newDomain, typeof(PluginSandbox).Assembly.ManifestModule.FullyQualifiedName,
            typeof(PluginSandbox).FullName
            );
        newDomainInstance = (PluginSandbox)handle.Unwrap();
