IBM Data and AI Ideas Portal for Customers
This portal is to open public enhancement requests against products and services offered by the IBM Data & AI organization. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

We are offering optimization solutions to our internal and external customer. We support this "idea" very strongly. In fact we think that must be a top priority feature. We opened a service case to state, that we expect a development in this direction (TS012980081).
I post the dialog here:
==============================Initial message=======================================
Dear Support team,
we need a CPLEX .NET API that not only supports classic .NET Framework but also modern .NET formats like .NET, .NET Core, .NET Standard, which are aiming multi-platform.
Apparently the Cplex .NET API is limited to support “.NET Framework” only : https://www.ibm.com/support/pages/cplex-optimization-studio-and-net-technology
Unfortunately, this limitation excludes Cplex as a solver library for an increasing number of optimization solutions which we develop for our customers and restricts our offer to use gurobi or xpress instead.
Can you tell us when you will be able to offer a Cplex .NET API in the mentioned modern formats as well?
==============================answer Support=======================================
We have this related wish (enhancement request) already registered:
https://ibm-data-and-ai.ideas.ibm.com/ideas/CPLEX-I-129
First thing would be to add your vote there. Ideas are regularly reviewed by our development team for future releases.
One other way would be to contact your sales representative, and explain the potential benefits you would get from such a new feature.
==============================our comment =========================================
Thanks you for your answer.
the fact, that cplex c# library only targets to .NET Framework, 1) makes it impossible to run the built SW on any other operating system than windows and 2) forces to run the SW in a .NET Framework environment. With the support for .NET (.NET core), the cross-platform successor to .NET Framework, these limitations no longer exist. Besides, .NET Framework is regarded to be deprecated and is no longer actively developed.
.NET (.NET core) is the de-facto norm for c# libraries nowadays.
The lack of this “feature” is really crucial and in many cases a knock out condition:
Without .NET (.NET core) we cannot build c#-cplex-based optimization SW for our customers’ linux servers, which often is requested.
Containerized applications typically base on linux platforms. We do not have an answer for this requirement in c# and cplex.
The consequence is that we cannot offer cplex for more and more use cases and therefore have to resort to gurobi or xpress
