Embed .net binary in a native executable

Is there a way to embed my .net executable (C#/VB.Net) in a ntive binary like a C/C++ file which will load the .net assembly on startup? Like building a native wall arround the .net assembly?

You could embed your .Net binary in the C++ project as a resource and load it runtime, but I doubt that is a recommended way to increase security.

Edit: Someone asked for source code and suggested that I make a comment instead of an answer. I've just signed up for StackOverflow and I don't have enough reputation to make comments yet. But here's some source I used at some point:

    public static int RunInternalExe(byte[] rawData, params string[] args)
    {
        Assembly asm = Assembly.Load(rawData);
        MethodInfo mi = asm.EntryPoint;

        if (mi == null)
            throw new Exception("Entry point not found");

        ParameterInfo[] prms = mi.GetParameters();

        object[] mtd_args = null;
        if (prms.Length > 0)
            mtd_args = new object[] { args };

        object result = mi.Invoke(null, mtd_args);

        if (result is int)
            return (int)result;

        return 0;
    }

Embed the managed .exe in your wrapper .exe and pass the raw data to the proc above.

MyTools.RunInternalExe(Resources.ExeData);

Ofcourse, if you want your wrapper .exe to be non-managed you'd have to translate the code above to C++ or some other language of your choice, that's kind of above my head right now...
