It's very hard for me to get away from C# because it's just so crazy productive. The tooling is fanstastic and the runtime performance is more than good enough.
One thing I found was that surprisingly the C# code I write outperforms the C++ code I used to write at equal development times.
I was good at C++, but the language has so many footguns and in general is so slow to develop in that I would stick to "simple" and straightforward solutions. I avoided multi-threading like the plague because it was just so hard to get right.
Meanwhile in C# it's just so easy to sprinkle a little bit of multithreading into almost any application (even command-line tools) that I do it "just because". Even if the single-threaded performance is not-so-great, the end result is often much better.
Similarly, it's easy to apply complex algorithms or switch between a few variants until something works well. In C++ or even Rust, the strict ownership semantics makes some algorithm changes require wholesale changes to the rest of the program, making this kind of experimentation a no-go.
The thing that blows my mind is the "modern" approach to programming that seems to be mostly young people pretending that Java or C# just don't exist.
Have you seen what JavaScript and Python people call "easy?"
I saw a page describing a REST API based on JSON where they basically had thousands of functions with no documentation, no schema, and no typed return values. It was all "Just look at what the website JS does and reverse engineer it! It's so easy!"
I was flabbergasted. In Visual Studio I can literally just paste a WSDL URL into a form and it'll auto-generate a 100K-line client with async methods and strongly-typed parameters and return values in like... a second. Ditto for Linq-2-SQL or similar frameworks.
