无法启动程序C:\…\**.dll VB.net应用程序Visual Studio 2015

我已经在VB.net web应用程序上工作了一段时间，我不小心将“应用程序类型”设置从类库切换到了Windows窗体应用程序。我尝试构建，但失败了，但当我切换回时，程序将不再执行，显示错误：

无法启动程序“C:\Users\User\…\bin\Project.dll”
“C:\Users\User\…\bin\Project.dll”不是有效的Win32应用程序

在此之前，应用程序将构建良好。 此外，在项目的属性页中，“Web”部分显示错误：

尝试加载页面时出错
值不在预期范围内

构建输出没有提供任何关于意外行为的线索，它构建得很好，只是不会运行。该代码也具有完整的功能

我尝试过多次重新启动，删除/bin目录并允许它从头开始重建（然后在失败时恢复旧内容），设置启动项目，更改目标CPU和调试/发布模式。我已经尝试过ReSharper构建和Visual Studio构建。 我还尝试了针对“C:\Users\User…\bin\Project.vshost.exe”的生成配置，但这将执行，然后立即关闭。 我没有选项在项目设置的应用程序页面中设置“启动对象”，但这从来都不是问题。我以前从未需要以EXE为目标来运行我的应用程序。若我尝试其他应用程序类型，它会声明“在项目中找不到Sub-Main”

我无法重新创建该项目，因为它的大小，所以如果有人能提供一些见解，我会喜欢它，下次我会注意不要玩弄IDE设置

=======更新===========

因此，我通过将WebProjectProperties更改为：

<UseIIS>True</UseIIS>
<UseCustomServer>False</UseCustomServer>
<servers defaultServer="">

好了，终于找到了解决办法，希望这能帮助其他可怜的灵魂，他们最终也会遇到同样的情况

第一步是编辑project.vbproj文件并更改：

        <WebProjectProperties>
      <UseIIS>False</UseIIS>
      <UseCustomServer>True</UseCustomServer>
      <servers defaultServer="SelfHostServer">
        ...
      </servers>
    </WebProjectProperties>

重新构建，一切正常

        <WebProjectProperties>
      <UseIIS>False</UseIIS>
      <UseCustomServer>True</UseCustomServer>
      <servers defaultServer="SelfHostServer">
        ...
      </servers>
    </WebProjectProperties>

        <WebProjectProperties>
      <UseIIS>True</UseIIS>
      <UseCustomServer>False</UseCustomServer>
      <servers defaultServer="">
        ...
      </servers>
    </WebProjectProperties>
