Tier 4 languages

03501aa5-572b-4129-aa0a-9e9fe9f5d3fc

Tier 4 languages can be compiled to WASM modules but they don’t (or don’t fully) support even WASI Preview 1. In case they partially support WASI, they may still be used to implement stateless single-invocation workers which could be useful as parts of a bigger Golem application to expose some platform-specific functionality or third party libraries, for example.

The currently supported Tier 4 languages are:

  • C# - does not support reading from the standard input, so the stdio and stdio-eventloop calling conventions cannot be used. Parameters can be passed via environment variables and output can be written to the standard output.
