Unfamiliar with any game codebases or much C++, but I know in C we'd do zero-allocation or controlled arena allocation for "embedded" uses. I'd imagine Allocation tuning is always present. Was it much harder in C#?

.NET has support for stack allocation and manual management of native memory.

Many forget that MSIL is rich enough to support C++, initially via Managed C++, later replaced by C++/CLI.

The major features in C# 7.3 are related to slices, improved stack allocation and reducing copies of value types.
