System.DirectoryServices is not support dot net core 3.1 version on linux container.

Question

I'm trying to put a .NET Core 3.1 application listing users in an AD group into a .NET Core Runtime Docker container. Accessing the AD is being done with the help of a DirectorySearcher from the System.DirectoryServices namespace. Out of the box, .NET Core doesn't support this namespace, but by adding the package System.DirectoryServices (dotnet add package System.DirectoryServices) installed the required assemblies and the application runs fine on a Win10 machine.

Trying to let the app run in a Linux .Net Core Runtime container throws an exception because DirectoryServices doesn't support this platform

Is it support latest dot net version?

Answer 1

Hi @nandkishor ingavale ,

In .NET5, System.DirectoryServices.Protocols is support in linux, so try to change your framework to .NET5.
See:
Announcing .NET 5.0 Preview 5

Hope it could be helpful.

Only System.DirectoryServices.Protocols can be used on non-Windows platforms, as announced years ago.

You can also search for third party solutions if there exists any.

Answer 3

as 3.1 is out of support, I'd upgrade to .net 6 and System.DirectoryServices.Protocols. but the standard solution for 3.1 is ldap:
