This article mainly introduces "how to use Mono to compile and run C# to the WebAssembly platform". In the daily operation, I believe that many people have doubts about how to use Mono to compile and run C# to the WebAssembly platform. I have consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "how to use Mono to compile and run C# to the WebAssembly platform". Next, please follow the editor to study!

Because all major web browsers support WebAssembly, developers can now look for a new platform to deploy their applications. The standard toolchain provided by the WebAssembly team can only compile C and C++ into WebAssembly, but it doesn't help developers in other programming languages. Luckily for C # developers, the Mono project provides two different ways to support WebAssembly.

The first way is to run managed code (for example, C #) at run time (runtime) by using the Mono IL interpreter. The goal of this approach is to support rapid prototyping and rapid development. When the application is ready to be delivered to the customer, it is best to use the second approach. This method uses static compilation to generate a WASM file that can be executed locally by browsers that support WebAssembly.

To be able to create these WASM files, a new tool called mono-wasm has been introduced into the Mono project. It takes the C # language as input and generates LLVM binaries for use in the back end of LLVM WebAssembly. The target WASM file generated by mono-wasm contains all the dependencies needed for the execution of the C # program, including mscorlib.dll, C library files, and Mono runtime files. Because the LLVM linker recently added support for WebAssembly, mono-wasm supports incremental compilation. This approach can greatly reduce compilation time, and when you develop, there is no need to recompile code that has not changed (such as mscorlib.dll, Mono runtime files, etc.).

Although a lot of work has been done on the project, its lead developer Laurent Sansonetti points out that the project is still in the pre-test version (pre-alpha). In the recent short-term development phase, the main goal of the project is to fix the garbage collection mechanism and prepare for the release of a formal test version of alpha. The long-term development phase of the project will focus on reducing the size of the WASM executable (the size of a hello world sample program is 10MB) and updating the Mono compiler so that it can be compiled directly into WASM32, as well as improving interaction with C# and JavaScript.

At this point, the study on "how to use Mono to compile and run C# to the WebAssembly platform" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
