I use ManagementObject which is in System.Management.dll(4.6.0) in a class library
The class libray 's TargetFramework is netstandard2.0.
Then I reference the class library in a service whick is based on BackgroundService,
when I run the service , there is an error :
System.Management currently is only supported for Windows desktop applications.
why ?what should i do ?
Did you try to use .NET Framework 4.6.2 (package-provided) in all of code?
To check that WMI works, it has sense to try a traditional service: https://learn.microsoft.com/en-us/dotnet/framework/windows-services/walkthrough-creating-a-windows-service-application-in-the-component-designer (first without class library).
actually, the target framework of bottom class library is netstandard2.0,
and the target framework of the top service is net8.0,
when I run the service , it finds the system.management.dll which version is 4.0.0.0 automatic.
I explicit include system.management.dll from a nuget package which version is 9.0.1.
when I run the service , it finds the system.management.dll which version is 4.0.0.0 automatic.
But there is no version 4.0.0.0 dll.
when I explicit load the 4.6.1 dll , it said that System.Management currently is only supported for Windows desktop applications.

while the package is .netstandard 2.0, when hosted on .net 8.0, it only works on the windows O/S. to access the windows api, it needs the .net 8.0 windows desktop runtime support.
you could switch the top service to the desktop sdk:
https://learn.microsoft.com/en-us/dotnet/core/project-sdk/msbuild-props-desktop
but try setting the target framework of the top service to:
net8.0-windows
