What are some good examples of C# code architecture on GitHub (explanation inside)?

Question

C++ / C#

Good day!
After I learned the banal technology in programming and there are basic values, and found where to apply them, as a result, after a couple of months a problem arose ...
In the course of various developments, I ran into the problem that my colleagues had little difficulty maintaining my code and its maintenance (No, there is no spaghetti code). The problem is that I need to come up with something like this:

It is necessary to design in such a way as to maximize the number of objects and minimize the number of connections between them.

(that is, I need to understand how to split the system into subsystems and see how others do it and what approaches they use, etc.),
and I would also like to look at the code of various applications where there are different types of users (admin, client, etc. ) .d) well, or, something like a store (something like mini programs).
Thanks in advance!

Answer 1

In order for the code to be reusable and maintainable, it is worth following the SOLID methodology. This is exactly what OOP is. More precisely, an attempt to apply an OOP approach, similar to the original research of theorists, in the case of a frankly unsuccessful implementation.

For example, this is https://github.com/dotnet/core/blob/master/Documen...
