.NET Core 6 Windows Service集成EF Core后安装失败求助

问题描述 #

我做了一个用于学习的.NET Core 6 Windows Service示例项目：

• 未集成EntityFramework Core和EF SQLServer包时，使用InstallUtil直接指向Release目录下的exe文件，服务可正常安装并在控制面板中显示。
• 添加仅包含一个模型的DBContext及EF相关包后，安装流程中止并报错，已尝试使用32位和64位的InstallUtil，均无法解决。

已尝试的解决操作 #

• 检查发现Release目录缺少EF相关依赖的dll，尝试根据EF包的依赖项单独添加分析器包，但添加后对应的dll仍未出现在Release目录，安装依然失败。

求助 #

请问可能是什么原因导致这个问题？
