Considering that the .COM API is not maintained anymore, which API should we use as a replacement, knowing that :
Eikon COM APIs are in care & maintenance, meaning they're not being enhanced, but critical bugs will still be considered and fixed. I wouldn't necessarily recommend you to replace Eikon COM APIs in your applications at this time. Refinitiv will indeed be replacing Eikon COM APIs with a single library capable of retrieving all the data you require. However, we're not quite there yet. Today, if you had to replace Eikon COM APIs, to retrieve all the data you require you'd need to use two .NET libraries, neither of which is an official release and neither of which is formally supported by Refinitiv.
