How to grant ReflectionPermission with RestrictedMemberAccess to my application C#

Question

When I call GetTypes on the assembly I cannot see internal and private classes. I read I can get internal and private classes by adding RestrictedMemberAccess but I don't know how to do it.

Assembly assemlib = typeof(TabletDeviceCollection).Assembly;

foreach (Type type in assemlib.GetTypes())
{
    Console.WriteLine(type.FullName);
}

Thanks for any help.
