Publishing .NET Core C# self-contained application for linux architecture

Question

So I'm trying to host a discord bot on a Google Cloud Server. I've got a base-level bot that works and runs from my local machine. The bot is written in C# .NET Core framework for Windows 10 x64.

Before anyone says it's been solved before, I have found those solutions and nothing is helping me.

I'm trying to publish the .NET application to a linux format self-contained. So that I can deploy and run the bot on the linux server (Ubuntu 18.04-x64 [I cross-checked on the .NET website to make sure it was a deployable package]) I looked it up and found the command, and also the changes I had to make inside my .vsproj file.

Is anyone able to walk me through something I'm missing? Do I have to download the linux version of something to build for it... or whatever. I'm not really sure what I'm missing. Then from that, I know how to upload the files to my server, but how do I "remotely" execute the deployed application on the server?

Answer 1

Thank you to those who commented. Performed the update for my .NET Core framework to 2.1.500 and hey presto! Successfully published the application.
