Integrating .NET Core Consol Application into unity

Hi, I have a .net core console app library and I want to integrate it into unity so I can call functions from my console project. How can I do it?

Console app is not supposed to be integrated anywhere. You need class library type project for this. Having one, you may just copy resulting .dll file in Plugins folder and use as part of the project. And if you need console app and unity app to share same functionality, you create class library or unity class library (a class library with reference to unityengine.dll) and reference that library both in console app and in unity app.
But if you really want to integrate console app in unity, you may use Process class from .NET api to create a process and read/write data from/to it’s streams.

I want to call functions of this project

App and library are different things. In windows, app is .exe and library is .dll. In .NET there’s no thing like “console app library”, there are “console app” and “class library”.

To use class library from that project build it and copy to plugins folder or copy it’s source to plugins folder or made it a unity package with Unity - Manual: Creating custom packages.

If I copy the .dll file into the project, I get this error:
Assembly ‘Assets/BitcoinLib.dll’ will not be loaded due to errors:
Unable to resolve reference ‘System.Configuration.ConfigurationManager’. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.

I saw this post, but I don’t know how to add these dlls. I’m a beginner on this, sorry.

It says, you should just copy them to plugins folder manually.

Yap, but there are still a lot of errors.
