C# AppDomain: Execute assembly from entry point

I am trying to create a Windows sandbox application, building upon the "How to" found here: "http://ift.tt/1DhB6ji"

In the example it loads a specific type from a DLL whereas I would like to be able to execute an assembly from its entry point with restricted permissions.

The program I am using for testing purposes is a simple hello world application.

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
            Console.Read();
        }
    }
}

I have tried two different methods to try and achieve this.

Method 1.

Use the "MethodInfo.Invoke" method on the entry point of the assembly.

MethodInfo target = Assembly.Load(assemblyName).EntryPoint;
target.Invoke(null, parameters);

This produces a Method Access Exception due to the main method being non-public. A simple way around this would be to make the main method public but I will not have this sort of access to the assemblies that are intended to be used with this application.

Method 2.

Use the "AppDomain.ExecuteAssembly" method as shown below.

newDomain.ExecuteAssembly(filePath, parameters);

This requires that the app domain has both File IO Permission and UI Permission for the assembly to be executed but I want to be able to restrict the assembly from having these permissions.

Is there a way to execute an assembly from it's entry point within a permission restricted app domain?
