问题描述
我创建了一个在 Visual Studio 2019 中按预期进行调试和发布的工作服务.该服务监视要创建的 .csv，并使用正确的编码 (UTF-8) 将其重写到另一个目录.当我发布它并创建一个 Windows 服务时，在启动 Windows 服务时，我收到 错误 1053:该服务没有及时响应启动或控制请求.据我了解，我的 OnStart 返回的速度不够快.但我不确定如何调试.
I've create a Worker Service that works as intended on both debug and release in Visual Studio 2019. The service watches for .csv to be created, and rewrites it with proper encoding (UTF-8) to another directory. When I've published it, and a Windows Service is created, on starting the Windows Service I am receiving Error 1053: The service did not respond to the start or control request in a timely fashion. From what I understand, my OnStart is not returning quick enough. But I am unsure of how to debug.

推荐答案
我不知道为什么我一开始没有这样做.我向那些花时间看这个的人道歉.我最终使用 .WorkerService.exe 在 Powershell 中运行该应用程序.这引发了我缺少 ASP.net Core 运行时的错误.我之前安装了 .NET core 的运行时，最近安装了 5.0.此辅助服务必须需要具有托管运行时的特定 ASP.Net Core:下载.服务现在开始没有问题.
I'm not sure why I didn't do this in the first place. My apologies to those who took their time to look at this. I ended up running the application in Powershell with .WorkerService.exe. This threw the error that I was missing the runtime for ASP.net Core. I had previously installed the runtimes for .NET core and recently the 5.0. This worker service must need the specific ASP.Net Core with hosting runtime: Download. Service starts without issue now.
