I agree, C# is my language of choice and I've been using it professionally for over 5 years. I use it for personal projects as well.

I'm referring to all the stuff C# has that Java doesn't. Async, ref/in/out keywords, extension methods, linq, lots of stuff. Maybe it's not a big deal, like I said I wouldn't really mind it. I just think Java is a bit simpler in this regard which is an advantage for beginners.

Some differences where I prefer java are checked exceptions and imports. C# usings are ambiguous, it can be difficult to figure out where things are coming from for code samples outside an IDE. And checked exceptions are just good IMO. I've never seen why people dislike them, having used Java and C# I think Java does it better. It's easy to miss exceptions in C#, I wish library developers could use checked exceptions to tell me which exceptions I should worry about.

Anyway both languages are great first languages and great general purpose languages. Highly recommend both.

Thanks for taking the time to respond. Ultimately though, most of those aren't required from the beginning, but the syntactic sugar, abstractions, and performance gains from them are amazing.

You probably already know, but I'll opine a little bit about extension methods. I use them a lot.

Entities > Repositories > Functionality. All split out.

- Entities (pretty much just gets and sets, nothing more than necessary).

- Repositories via extensions to determine where the data comes and goes from (some data comes from SQL, some from Redis, some from Postgres, doesn't matter since it's split out) and any particular queries you need for optimizing things.

- Functionality via more extensions without adding additional code to the entities.

Separation of purpose/use.

I may or may not have completely replaced our data layer in the middle of the height of our season with no interruption. Little bit passionate about this one.

Would you happen to have something like a github repo with examples of those repositories? I'd be interested in seeing that.

Personally I'm not a big fan of copious extensions. I use them some times but I'd describe my usage as sparingly.

I wish. It's on Github, but my hands are tied and I can't share them since it's someone else's property now (hooray for exits, I think).

It's mostly a thought process...

I have or need something (entity), lets get data about it (repository/extensions), we need to do something with this now (only extensions).

Lots of "static" and "this" involved, but the separation and eventual simplicity makes it worth the effort.

Edit: I tried going through some of them to anonymize some for examples, but it felt like treading in dangerous territory.
