MicroCS wiki

C# for microcontrollers: a compact C# compiler and VM that runs on ESP32, Raspberry Pi Pico, STM32, nRF / Zephyr boards, Arduino and the PC.

New here? Pick the guide for your board below - each one goes from an empty folder to running C# on the chip, step by step. The reference pages explain every option.
