What version of Docker.DotNet?: 3.125.15

(paste your output here)

Steps to reproduce the issue: 1.delete all containers using Docker Desktop 2.create client: DockerClient client = new DockerClientConfiguration(new Uri("tcp://localhost:2375")).CreateClient(); 3.attempt to get lit of containers var containers = await client.Containers.ListContainersAsync(new ContainersListParameters { All = true // Include stopped containers in the list });

What actually happened?: error thrown: Category: OBSStartupService.Worker EventId: 0 Queues Startup error: Object reference not set to an instance of an object. Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Docker.DotNet.QueryString1.<>c__132.b__13_0(PropertyInfo p) at System.Linq.Enumerable.WhereArrayIterator1.MoveNext() at System.Linq.Enumerable.<Any>g__WithEnumerator|36_0[TSource](IEnumerable1) at System.Linq.Enumerable.AnyTSource at Docker.DotNet.QueryString1.FindAttributedPublicProperties[TValue,TAttribType]() at Docker.DotNet.QueryString1..ctor(T) at Docker.DotNet.ContainerOperations.ListContainersAsync(ContainersListParameters, CancellationToken ) at OBSStartupService.Services.QueueStartupService.GetContainerByName(DockerClient, String) at OBSStartupService.Services.QueueStartupService.GetOrCreateContainer(DockerClient, String) at OBSStartupService.Services.QueueStartupService.StartContainer(DockerClient) at OBSStartupService.Services.QueueStartupService.StartQueues() at OBSStartupService.Worker.ExecuteAsync(CancellationToken)

What did you expect to happen?: an empty list of containers would be returned

Additional information: when running in debug in VS 2022, it works as expected. When deployed to a test environment (windows 11 azure VM), and installed as a windows service like: sc.exe create "Omedus Base Station Startup Service" binpath= "C:\Omedus\OBSStartupService.exe"

it throws the above error.

dotnet --info from the test PC is shown below

I changed compile options to not "trim unused code" and now it all works fine.
