How to remove Sheet Set association programmatically using C# .NET API?

[varshaauti27]

Hi all, 

I have layouts created using temporary DST(Drawing Sheet Set) file. After creating the layouts, I programmatically delete the Sheet set from the DST file and the delete the DST file itself. Although everything works as expected, I encounter a "Lost Set Association" warning when I reopen.

Any assistance or guidance on how to remove the sheet set association programmatically would be greatly appreciated.

@varshaauti27  I believe you can just delete the AcSheetSetData Dictionary.
