DDL (data definition language) operations are not natively supported in the Pro SDK. You need to use the geoprocessing routines to run the "Delete" tool to delete the dataset.

I hope this helps,

There is a sample that deletes a table from a File Geodatabase: Edit Operation Row Event

You might be able to use this snippet from this sample:

Hi Rich,

Thank you for answering my question.

I'll give "Delete" tool a try.
