Do you have the System.DirectoryServices.Protocols.dll in your reference assembly folder?

[OnurGumus]

@Thorium yes, it is added as a nuget package. VS build and run is fine but dotnet publish fails.

[OnurGumus]

Any updates on this? This is a show stopper!

I don't use dotnet publish, but it sounds to me that the database driver is depending to this dll that is not found for the path that the publish-command is looking. Maybe there is a way to 1) copy the dll manually to the correct path 2) or have some parameter to publish to force including/copying the reference dlls.

@Thorium strangely those steps don't matter. I am a bit confused.

I think we would need some support from dotnet.exe publish here, what is happening in the process different than with the normal build.

I don't see this error any more with .net core 3.1
