通过 WIX 安装程序安装带有 CLI 项目 EXE 的 C# 不起作用

我有一个通过DLL调用C++ CLI的C#项目。它将一个字符串返回到 C#，该字符串显示在按钮事件的文本框中。我通过在 C# 项目属性中添加此 dll（名为 MyDll.dll）作为引用来添加它。我正在尝试使用 wix 工具集创建安装程序。这是源代码。

C# 代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using MyDll;
namespace MyProject
{
    public partial class Form1 : Form
    {
        public Class1 obj = new Class1(); 
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            string str = "";
            string str_new = obj.MyFunc(str);
            textBox1.Text = str_new;
        }
    }
}

C++ 命令行代码

#include "stdafx.h"
#include "MyDll.h"
namespace MyDll
{
    Class1::Class1(){}
    Class1::~Class1(){}
    Class1::!Class1(){}
    String^ Class1::MyFunc([Out] String^ str)
    {
        str = "My C++/Cli DLL";
        return outVal = str;
    }
}

C++ CLI 标头

// MyDll.h
#pragma once
using namespace System;
using namespace System::Runtime::InteropServices;
namespace MyDll {
    public ref class Class1
    {
        // TODO: Add your methods for this class here.
    public:
        Class1::Class1();
        Class1::~Class1();
        Class1::!Class1();
        String^ MyFunc([Out] String^ str);
        String^ outVal;
    };
}

我的安装程序工作正常。它在指定的路径上安装一个exe和一个dll（MyDll.dll）。但是当我运行 exe 时，它什么也没做。如果我将已安装的 exe 替换为在我的 C# 项目的 bin 文件夹中创建的 exe，那么它可以正常工作。如何解决此问题？

谢谢
