How to create a text editor in VisualStudio2017?

Question

C++ / C#

Actually there is a task to develop a text editor (basic manipulations with documents, formatting, fonts, design settings). I am a beginner in programming (not quite, I wrote simple JS scripts for websites), I know basic things (cycles, methods, classes, etc.), I have a basic understanding of OOP, but I have not used it in practice. From real experience, simple games in Unity, website development (frontend, so not really). Development time 4 months.
Specifically, according to the editor, in VS2017 I made a simple calculator and other crayons of the program (with a familiar interface). Development cannot be abandoned. And the questions themselves, where do I start? In which direction to dig? Maybe there are source codes, tutorials. Need advice from an experienced developer on where to start, and how not to overwhelm the project.

Answer 1

In order not to overwhelm the project - you need to start with a description of the project - tobish technical specifications. And then, based on it, determine what you need and how to do it.
PS There are quite a few programming languages ​​in VS2017. And platforms. Just start with this.
