I'm developing an "ASP.Net Core Web API" in Framework .Net 8.0 working with Microsoft WSUS, I have referenced the file :

C:\Program Files\Update Services\Api\Microsoft.UpdateServices.Administration.dll

When I try to run the code :

AdminProxy proxy = new AdminProxy();

objUpdateServer = proxy.GetRemoteUpdateServerInstance(sServerName, false, iPort);

I get this exception at the 2nd line :

{"Could not load file or assembly 'Microsoft.UpdateServices.BaseApi, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.":"Microsoft.UpdateServices.BaseApi, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"}

How can I fix this problem ?

I had developed a WCF service in Framework 4.7.2 with the same referenced dll and this was working properly.

Thanks per advance for your help :)
