我不会保留这两种解决方案，而是将网站项目转换为 WAP。

您需要将网站项目中 app_code 文件夹中的所有内容移动到单独的类库中，或者直接将它们包含在 WAP 中（可能没有 app_code 文件夹，因为这具有特殊意义），在这种情况下，它们将是编译到主 WAP 程序集中。

您可能必须使用名称空间等才能使其正常工作，但影响应该是最小的。主要区别（和好处）是代码是在编译时构建的，并且您的源代码 (*.cs) 没有部署到服务器。

另请注意，在 VS 中，有一个上下文菜单选项可将网站项目实体转换为 Web 应用程序实体。这将创建 WAP 所需的 .designer.cs 文件，并在解决方案资源管理器中组织文件 - .aspx、.cs 和 .designer.cs 文件将显示为可扩展节点。

这是 MSDN 上一篇关于转换过程的优秀文章。

运行 WAP 后，添加服务就像right click - add new item...
