Rust for C# and .NET developers guide by Microsoft

Rust for C#/.NET Developers is a concise, practitioner-oriented mapping aimed at experienced C#/.NET programmers who are new to Rust. It assumes familiarity with .NET but no prior Rust knowledge, and it aims to show how common .NET concepts translate into Rust - what maps neatly, what looks different, and what is a radical departure (notably memory and resource management). The authors, themselves C# developers who learned Rust, distilled months of experience into a compact reference with brief examples, links to further reading, and clear non-goals: it is not a comprehensive language tutorial, a design-patterns manual, or a cookbook that makes the reader proficient in Rust by itself.

The content surveys language and ecosystem topics in practical detail: scalar and structured types, strings, custom types (classes, records, structs, interfaces, enums), members, generics, polymorphism, inheritance-like patterns, equality, nullability, casting, operator overloading, documentation, and local functions/closures. It also covers memory and resource management, threading and synchronization (including producer-consumer), testing, benchmarking, logging, conditional compilation, configuration, LINQ equivalents, metaprogramming, asynchronous programming, project structure, and build processes. Examples contrast C# and Rust syntax and behavior where useful, and the guide emphasizes learning Rust idioms rather than relying solely on .NET analogies.
