Microsoft Flight Simulator 2024: A Deep Dive into WebAssembly Module Development

Microsoft Flight Simulator 2024 leverages WebAssembly (WASM) modules as the new standard for add-ons, enhancing security and portability. This article details the Visual Studio toolset for WASM module development, including direct compilation of C/C++ projects to WASM, debugging WASM modules, and extensive support for standard C/C++ libraries. It also covers various WASM module usage scenarios within the game (standalone, gauge, airport, and system modules), highlighting key information on APIs, file access, upgrading from MSFS 2020, and known issues and limitations. Developers should note the deprecation of the legacy Gauge API in favor of the Vars and Event APIs.
