Greetings,

In .net framework 4.7 (WCF service running on Windows Server) I am able to use:

XMSC.WMQ_CONNECTION_MODE = XMSC.WMQ_CM_CLIENT_UNMANAGE

If the full blown client has been installed on the Windows server.

When I try running my app in a Linux based container using debian based mcr.microsoft.com/dotnet/aspnet:6.0 image that has the full blown IBM client runtime installed via dpkg like so in my docker file

RUN dpkg -i ibmmq-runtime_9.3.3.1_amd64.deb

 I get the following error if I set the above property:

CWSMQ0008E: XMSC_WMQ_CONNECTION_MODE is not supported in this release. The application has attempted to use a feature or capability that is not supported by the current release of the software. Remove the code that attempts to use this capability or update to a later release of the software if available.

I am using TLS to connect to my QManager if it makes any difference.... Is it possible for me to reference the managed version NuGet Gallery | IBMXMSDotnetClient 9.3.3.1 but configure it to use the full blown client install instead of the nuget package? Or alternatively can I force it to run the full blown client in managed mode like was possible in .net framework? 

MQ /XMS .NET Standard libraries don't support Unmanaged mode. You will have to use managed mode to use the MQ/XMS .NET Standard libraries for the .NET 6 applications.You could use NugetPackage or Client install to use the MQ/XMS .NET Standard libraries.Following KC link has some information 
Using IBM MQ classes for XMS .NET
