C# always supported stack allocations and always supported things like stack-based pointer operations. It just tagged a lot of it as "Unsafe" and/or required the `unsafe` language keyword (and concomitant security escalation in the old Framework security model where assemblies that used `unsafe` code needed additional code certificates to be installed into places like the GAC). The "advanced" stuff is very much about bringing Rust-like lifetimes to the language and moving the powers and capabilities outside of the `unsafe` keyword world, by making it much less unsafe in similar ways to how Rust does lifetime/borrow-checking but converted to C#/CLR's classic type system. It's adding the "too clever" memory model of Rust to the much simpler memory model of a GC. (GCs are a very simple memory model invented ~70 years ago.) |
