The only reason you need your IDE to write classes for you in C# is because C# has nominal typing and tons of boilerplate (ex: getHashCode()).
I've written millions of lines of C# and hundreds of thousands of TypeScript, and I use JetBrains JDEs for both these days. Class generation is absolutely not something I need or miss in TypeScript.
I also write TypeScript, daily for the past 5 years. I wasn't talking about boilerplate, the C# analyzers like ReSharper can determine which variables are you probably going to use, what methods are you going to call, and what parameters will you give them. I'd love to have them in TS.
That boilerplate is automatically added by the compiler. You don’t need an IDE to do it. There are tons of examples of very lean C# that can be written in notepad.
Before records, the compiler did not generate code required to properly use classes (or even structs) as value types. There's a reason everyone is so excited about records.
I have apps with thousands of lines of implementing comparison/equality interfaces, overloading operators, etc. for my data objects. You can definitely write it all in Notepad, but it would be a massive waste of time.
