Recently developed a Windows Service Project

A recent project involves Windows Service and WebService. I want to write down a little bit of experience in this project, which may be helpful to my friends who encounter the same problem, haha.

At the beginning of the project, I didn't plan to use the layer-3 architecture that I used to use, because the project is too small, A solution contains only one web site and one Windows service. The web site contains simple WebService and several pages. The only special point is that WebService is written in VB, while other pages use C #. For ease of writing, I copied the sqlhelper class that was frequently used in the past to the app_code folder under the Web site, because WebService (the class name is ibmload. CS) when using the VB language, an error is reported during compilation, indicating ibmload. CS and sqlhelper. CS cannot be stored in the app_code folder at the same time, because either of them uses VB or C #. For this reason, I added another class library project and put sqlhelper. CS in this class library project. Later I thought about how to separate layers in the previous mode. In this case, I will reference other projects in the Windows service project, such as idal, sqlserverdal, and entity, which is not the same as when I used Windows service, all of the projects I wrote earlierCodeThey are all put together, and chaos is a little messy, but they don't feel any bad about themselves. In this case, the code is written in other places, and there are few lines of code in Windows service, but I am not used to it.

However, an error occurred when I started the service after installation, for example:

It was discovered later that Windows Service referenced several other projects and generated a bunch of DLL files, while I used the previous method during installation, only one EXE file is copied to the target server for installation. In fact, the actual business logic of this service is installed in the pile of DLL files without DLL files, at this time, Windows service is like a blank piece of white paper, so there is nothing to do.

so I unmount the installed Service, copy the EXE and DLL files to the target server at the same time, and then run the installation. After the installation is complete, start the service to run properly. But now I have a question: is it necessary to implement it in a hierarchical manner if it is just a separate Windows Service Project? Hope you can give me some advice.
