Ask HN: Do you use either C# or Java in your professional work?

I am curious to know how many people are using Java (and C#) as their primary bread-maker.

I want to get a reality check because from what I see on here, it seems like only a handful languages are ever discussed. I don't work in either language professionally and I feel I'm missing out on major career opportunities.

I understand the reasons why Java/C# don't get discussed too much, I just want to know how many of us use it.

Thank you.

EDIT: Thank you for the responses so far, it seems that I am indeed throwing away a lot of career opportunities.

As an aside, for the Java stack, is learning Core Java , Servlets / JSP, Hibernate (or other ORM) enough to meet the basic skills required for most of these jobs?

C++ and Python are my primary languages, the ones I choose for my own projects, and the leads on my CV. I also do a fair bit of C# and Java, simply because they are so commonplace. For my current contract, C++ is the core lang, but extensions are in C#. On a previous project servers were in C++, and GUIs in Java. There's an awful lot of C# and Java out there, often in CRUD "enterprise" style systems.

The team I work with use the Spring framework for backends and REST APIs, and most of what we make are webapps. I also know a good number of companies (at least in my area) that hire java developers.

As for C# I would image there are a decent number of people who use it for .NET. The only time I ever used it was in my senior capstone, though.

I work full time remotely using Java. There are tons of Java jobs out there doing interesting work. On the remote front Java isn't that popular but it's still possible to find remote friendly Java companies (just not as ubiquitous as Ruby/Python/JS remote jobs).

Edit: I've been working with Java professionally for just short of 8 years.
