我正在尝试像这样升级我的应用程序:

这是我为该特定项目设置的属性:

我做错了什么？这个异常是什么意思？

Answer 1

我同意 Hans Passant 的评论:

The most basic mishap is that the name you used in the ServiceManifest.xml file does not match the name of the .exe that your project generates

它在您的调试输出中也可见，因为构建成功但发布失败。

========== Build: 1 succeeded, 0 failed, 46 up-to-date, 0 skipped ========== ========== Publish: 0 succeeded, 1 failed, 0 skipped ==========

它可能以多种方式发生，很可能是由于重命名项目或重命名程序集名称。如果您重命名项目或项目的 Assembly Name，您的构建可执行文件将根据该名称。考虑以下情况。

我将 Assembly Name 从“MyService”重命名为“MyRenamedService”。因此构建可执行文件将是 MyRenamedService.exe。因此，您必须在 ServiceManifest.xml 中进行设置。

<CodePackage Name="Code" Version="1.0.0">
    <EntryPoint>
      <ExeHost>
        <Program>MyRenamedService.exe</Program>
        <WorkingFolder>CodePackage</WorkingFolder>
      </ExeHost>
    </EntryPoint>
</CodePackage>

确定构建可执行路径的最佳方法是构建解决方案。它将在输出窗口中显示可执行文件的完整路径。

1>------ Build started: Project: Web1, Configuration: Debug Any CPU ------
1>Web1 -> C:\.....\Application2\Web1\bin\Debug\net461\win7-x64\MyRenamedService.exe
2>------ Build started: Project: Application2, Configuration: Debug x64 ------
========== Build: 2 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========

这里的Web1是我开始的Project Name，MyRenamedService.exe是build executable name(因为我重命名了Assembly Name)，应该在ServiceManifest.xml 如上所示。
