我在Visual Studio 22中使用ASP.NET核心API模板创建了一个小API，目标是.NET6。为了测试/调试，我使用控制台应用程序启动API，一切正常。但为了生产，我需要从Windows服务启动此API，但我不知道如何制作。
我可以简单地把.exe文件放在服务所在的文件夹中并调用它，但目前为止，如果没有用户登录，控制台应用程序将不会启动。因此，我们的想法是将API与所有服务打包在一起，并在Windows服务启动时启动它。
我做了一个小测试，创建了一个静态类名“Test.cs”，方法名为“Start”，从“Program.cs”复制所有代码，并从测试应用程序调用“Start”方法。API启动并保持侦听端点，但由于某种原因，没有从项目控制器文件夹Map控制器。
all OK when starting API from default
controllers not mapped when start API from static method
