Loading assemblies dynamically using my own ResolveEventHandler

Hey all, so I've noticed that when I load assemblies dynamically in my
own custom ResolveEventHandler that their Modules do not get returned
when I invoke
Process.GetCurrentProcess().Modules

Here is some pseudo code to show what I'm talking about:

public class Foo
{

public Foo ()
{
    SomeClassInDynamicallyLoadedAssembly myObj = new
SomeClassInDynamicallyLoadedAssembly();
    foreach (ProcessModule module in
Process.GetCurrentProcess().Modules)
    {
      Trace.WriteLine("module: "+module.FileName);
    }
}

public static int main (string [] args)
{
    AppDomain.CurrentDomain.AssemblyResolve += new
ResolveEventHandler(CurrentDomain_AssemblyResolve);
    Foo foo = new Foo();
}

private static Assembly CurrentDomain_AssemblyResolve(object sender,
ResolveEventArgs args)
{
    // get the bytes for this assembly - wherever it might be (could be
an embedded resource)
    return Assembly.Load(bytes);
}
}

I can see that the assembly is getting loaded without issue since I can
use the classes that are stored in it. But that module doesn't appear
in the current processes list of modules.

any suggestions?

Thanks,

Hmm... I guess I'm not too likely to get an answer to this question -
doesn't seem like there are many resources on this stuff.

One thing I've been experimenting with is that I can find the
dynamically loaded assemblies in both of the following collections:
AppDomain.CurrentDomain.GetAssemblies()
Assembly.GetExecutingAssembly().GetReferencedAssemblies()

Oddly enough the referenced assemblies seems to only include the dll's
that are embedded or contained in the GAC... not sure if that is
entirely accurate, but that seems to be what it is. Whereas the
GetAssemblies method invocation will return all of those assemblies, in
addition to any assemblies that you might have added in your
references.

Strange...
