Golang を DLL にパッケージ化できますか?

package main
import "C"
import "fmt"
//export PrintBye
func PrintBye() {
    fmt.Println("From DLL: Bye!")
}
//export Sum
func Sum(a int, b int) int {
    return a + b;
}
func main() {
    // Need a main function to make CGO compile package as C shared library
}

go build -buildmode=c-shared -o exportgo.dll exportgo.go

using System;
using System.Runtime.InteropServices;
namespace HelloWorld
{
    class Hello 
    {
        [DllImport("exportgo.dll", EntryPoint="PrintBye")]
        static extern void PrintBye();
        [DllImport("exportgo.dll", EntryPoint="Sum")]
        static extern int Sum(int a, int b);
        static void Main() 
        {
            Console.WriteLine("Hello World!");
            PrintBye();
            Console.WriteLine(Sum(33, 22));
        }

csc importgo.cs

>importgo.exe
Hello World!
From DLL: Bye!
