Why so many *_Expressions_xxxxx.dll files are generated in the DU project folder?
Issue: Lots of *_Expressions_xxxxx.dll files remain in DocumentUnderstanding project.
Analysis:
The *_Expressions_xxxxx.dll files will be generated during the compile and published a DU template project, and will be cleaned automatically after publish is finished.
However, if the publish is terminated by accident (for example kill Studio process), the dll files will remain undeleted.
Resolution:
These dll files can be removed manually without any impact. And will be automatically cleaned after next successful publish.
