SAP Business One DI API for ASP.NET Web Application

I developed one console application using DI API(x64). Now I am trying to develop a web application using the same code but getting the following error in the very first line

SAPbobsCOM.Company sboCompany = new SAPbobsCOM.Company(); //in this line

Retrieving the COM class factory for component with CLSID {632F4591-AA62-4219-8FB6-22BCF5F60090} failed due to the following error:

80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

I have tried changing Platform target (x84, any, x64) but no luck. I also have Enabled 32-Bit Applications on IIS.

I am using Visual studio 2017 community version and Windows 10(x64).

I have no idea why I am getting this error as its perfectly working for my console application. I have seen some are suggesting to use DI Server for web application but I am wondering if its possible to use DI API as I won't have much traffic.

Any help would be highly appreciated.
