I see `dotnet watch` being mentioned for code hot reload which is such a great feature for quickly iterating on a game. Not having to restart the whole game just because one has changed a few if statements and values really helps staying in the flow.
But I'm still not too enthusiastic about having GC in C# which is why ideally I'd like to start making a small 2D game just with SDL3 and C++ but how could I get this nice hot reload workflow there? I don't have the money to pay for expensive proprietary tools like https://liveplusplus.tech so what can I do?

Also, how does one even do modern C++ these days? Is it pos

sible to have big C++ code bases that still compile fast these days? Is CMake 4 good™ now? Are modules really there yet? I rely on clangd as LSP for working with C++ but I read that clangd still fundamentally struggles with C++ modules https://chuanqixu9.github.io/c++/2025/12/03/Clangd-support-f... and it's so bad that there has even been some effort going into making a new C++ LSP https://github.com/clice-io/clice
