> Pattern with context property causes PlatformNotSupportedException on Linux
> ---------------------------------------------------------------------------
>
> Key: LOG4NET-652
> URL: https://issues.apache.org/jira/browse/LOG4NET-652
> Project: Log4net
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.10
> Environment: Linux (Docker), .NET Core 2.2, .NET Core 3.1
> Reporter: Andreas Bilger
> Assignee: Davyd McColl
> Priority: Major
> Labels: .net-core, Docker, Linux
> Attachments: ConsoleApp1.zip
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> As mentioned in LOG4NET-429 and LOG4NET-421 (introduced in LOG4NET-205),
> having a custom property in a layout pattern makes each each log event
> resolve the (Windows) user name with
> {code:c#}
> log4net.Core.LoggingEvent.get_UserName()
> {code}
> which calls
> {code:c#}
> System.Security.Principal.WindowsIdentity.GetCurrent()
> {code}
> On Linux this leads to an internal exception:
> {code:bash}
> System.PlatformNotSupportedException: Windows Principal functionality is not
> supported on this platform.
> {code}
> This happens with versions 2.0.10 and 2.0.11 on .NET Core 2.2 and .NET Core
> 3.1.
> I attached a small console application project for reproduction in a docker
> image:
> * Extract the zip
> * Run {{docker build . -f Dockerfile -t log4net.test:latest}} to build a
> Linux docker image and compile the code
> * Run {{docker run --name l4n -it --rm log4net.test:latest}} to run that
> image in a docker container and open an interactive shell
> * And in the shell, run {{dotnet ConsoleApp1.dll}} to execute the compiled
> assembly
> With internal debugging enabled, this produces the following console output:
> {code:bash}
