Hi Umair, 

At present we do not have support for converting an existing PDF document to PDF/A-1B in ASP.NET Core platform. We have already logged a feature request for this. Currently we do not have any immediate plans to implement this feature. We will let you know when this feature is implemented. 
Please let us know if you have any concerns on this.
