assembly saving correctly

i have unequivocally rudimentary formula beget an public plead slight contained type. slight gets called runs correctly, however i perspective generated public controlling reflector, i don't type.

below illustration code:

namespace consoleapplication2
{
    category proggy
    {
        open stationary vacant main(string[] args)
        {
            var ab = appdomain.currentdomain.definedynamicassembly(
                new assemblyname() { name = "myassembly" },
                assemblybuilderaccess.runandsave);
            var way = ab.definedynamicmodule(ab.getname().name);
            var typebuilder = module.definetype("mytype");
            var ctr = typebuilder.defineconstructor(methodattributes.public, 
                callingconventions.standard, type.emptytypes);
            var ilgc = ctr.getilgenerator();
            ilgc.emit(opcodes.ldarg_0);
            ilgc.emit(opcodes.call, typeof(object).getconstructor(type.emptytypes));
            ilgc.emit(opcodes.ret);
            var slight = typebuilder.definemethod("mymethod", methodattributes.public,
                typeof(int), new[] { typeof(string) });
            var ilg = method.getilgenerator();
            ilg.emit(opcodes.ldarg_1);
            ilg.emitcall(opcodes.callvirt, typeof(string).getproperty("length").getgetmethod(),
                null);
            ilg.emit(opcodes.ret);
            var form = typebuilder.createtype();
            ab.save("mytestasm.dll");
            var inst = activator.createinstance(type);
            console.writeline(type.invokemember("mymethod", bindingflags.invokemethod, null, inst,
                new[] { "myteststring" }));
            console.readline();
        }
    }
}

and here analogous disassembly reflector:

.assembly myassembly
{
    .ver 0:0:0:0
    .hash algorithm 0x00008004
}
.module refemit_ondiskmanifestmodule
// mvid: {0b944140-58d9-430e-a867-de0ad0a8701f}
// aim runtime version: v2.0.50727

... ...

{
    .class private automobile ansi <module>
    {
    }
}

can anyone assistance me removing public morally saved?
