我想在Visual Studio中使用weka。因此，我使用ikvmc -target：library weka.jar命令使用IKVM将weka.jar转换为weka.dll。转换成功，但是在命令提示符下，我从ikvm收到很多警告。

我将weka.dll添加为Visual Studio项目中的参考，并尝试使用一些类。
但是我不断收到错误消息，例如“ weka.core”名称空间中不存在“类型或名称空间名称” Instance”（您是否缺少程序集或引用？）
这是我的示例示例代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using weka;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
weka.core.Instance
}
}
}
