Is System.ServiceProcess.ServiceBasespportdn.Net 6 on Wndows platform?

[jojopeter]

In a .NET 6 Windows service application, we have a reference to the class 'System.ServiceProcess.ServiceBase' from 'System.ServiceProcess.ServiceController.dll'. However, when we decompile the code, we notice that the methods appear to be throwing unsupported exceptions, as shown in the sample code below:

public ServiceBase() { throw new System.PlatformNotSupportedException(System.SR.PlatformNotSupported_ServiceController); } protected virtual void OnStart(string[] args) { throw new System.PlatformNotSupportedException(System.SR.PlatformNotSupported_ServiceController); } protected virtual void OnStop() { throw new System.PlatformNotSupportedException(System.SR.PlatformNotSupported_ServiceController); }

Interestingly, we do not encounter any exceptions at runtime, even though we are instantiating the ServiceBase class.
question is: Is the ServiceBase class truly unsupported in .NET 6 on Windows platform ? If it is unsupported, why are there no exceptions thrown at runtime when using it?
