UseOptimizedNamespaces never finishes

When I try using the UseOptimizedNamespaces() extension method, the serialization of the objects never finishes.

This is how I do the serialization inside a custom OutputFormatter:

public override Task WriteResponseBodyAsync(OutputFormatterWriteContext context, Encoding selectedEncoding)
{
    var configurationContainer = new ConfigurationContainer()
        .UseOptimizedNamespaces();
    var serializer = configurationContainer.Create();
    var result = serializer.Serialize(context.Object);
    return context.HttpContext.Response.WriteAsync(result);
}

Am I doing something wrong or is this a known problem? I could not find an issue that describes this problem.

I have not been able to reproduce the bug with a unit test using this repo. It must have to do something with the code around the serialization. I will open a new issue, if I can narrow down the bug.

I do not have a Unit Test. Maybe I can tell you more next week.
