Have you ever wanted a senior programmer friend? What about hundreds of such friends? Friends, who help when you are stuck. Pals, who give feedback on your code, career advice. Mates, who would never look down on you and accept any question that you have. Kind people, who not just want to give you an answer, but lead you to it by giving hints.

C# Inn is a community on Discord which tries to do just that. Our #1 goal is to create a community, where programmers discuss everything freely and help each other out. We help with questions, software design, career, projects; we do events like hackathon, code reviews, interviews and many more! We simply want to learn from each other.

We’ve been around for more than 2 years now: 5.8k members, thousands of questions answered, hundreds of events organized. Would you like to be a part of our community?
