Strict nulls, pattern matching, a really mature and easy to use async ecosystem (it invented async/await), even a lot of the low level stuff is there (unsafe{} blocks ala rust and manual memory management where needed).
C# is nice, but it is nowhere near Rust in terms of safety or expressiveness. Thankfully they are finally adding discriminated unions (sum types) and other sorely missing features.
Unsafe in C# is much more dangerous than unsafe in Rust, precisely because it doesn’t actually color a function. It just allows its body to use pointers. This is why you have methods in the CLR called “DangerousFoo()”, and the compiler does nothing to prevent you from calling them.
