Self hosted Webapi inside ArcGIS pro addin

Hi Everyone. My company has a AutoCAD Map 3D addin written in C# which is loaded when AutoCAD starts up. It has capabilities like linking a map object with actual SQL Database records. We had a legacy application written in Visual Basic 6 which used to communicate with the AutoCAD instance and send commands like link, unlink etc.

However we upgraded the legacy application to web based solution. I was able to achieve the legacy app behaviour by creating a self hosted WebAPI inside the AutoCAD addin that acts as a listener and I make calls from my Web based application from the web browser to the self hosted webapi running inside AutoCAD and then I perform the link, unlink operations inside AutoCAD and send the response back to the web browser.

Now my company wants to support ArcGIS pro along with AutoCAD. I tried creating a self hosted webpi inside the ArcGIS addin but I havent been able to get it running at all. I keep getting Microsoft.Aspnet.core dll's missing or some or the other dll missing. I have been struggling to achieve this functionality.

I have around 10 years of coding experience with C#, Asp.net, Blazor etc so I am sure I am not doing anything wrong with the code. I even tried using websockets, signalR to act as a listener but nothing has worked.

Is it even possible to achieve this functionality with ArcGIS pro? Any suggestion is welcome. I just need to create a PoC to say that yes we can support ArcGIS pro as well.
