cil.js

cil.js is a MIT licensed .NET CIL assembly to JavaScript transpiler. In other words, cil.js enables you to write C# code and run it in a web browser, without any plugins.

It provides a small runtime library and a tiny version of mscorlib.dll.

While it is not production quality and is mostly a hobby project, it has support for the most important CIL features:

• Class, struct and enum types
• Virtual and interface methods
• Generics
• Int64 (emulation)
• Basic Reflection

Missing features:

• Multidimensional arrays
• Unsafe code
• Await/async
• Reflection.Emit
• dynamic
• others.

Acknowledgements

cil.js uses IKVM Reflection for working with assemblies.

A few tests and some mscorlib code is originally from the mono project.
