Why are my temp files not being cleared when using the .NET Pipeline API?
In .NET core, the finalizer is not called when a program exits as described on this page. Some engines maintain files in a temporary directory while they are in operation and these can remain if a .NET core application using one of these engines is closed.
To workaround this problem, you can either:
- Use the
SetAutoDisposeElementssetting to ensure elements are disposed when the Pipeline is disposed. - Explicitly call dispose on all engines before exiting the program.
