DotNet and DotNet Core projects
I've developed with C# since 2001; it's my bread and butter. Most stuff is either enterprise or commercially sensitive, but I do have some open source projects.
Simple, efficient, and tested .Net Core database migrations supporting multiple database technologies (by simple provider plugins - currently MySQL/MariaDB and Postgres).
Easy argument parsing for .Net Core applications. Uses fluent-style declarations for strongly-typed options (compulsory or not) and boolean flags, and has built-in help text rendering.
Extract structure from any text using a generic lexer.
Generic Markov chains
Simple pattern 'learning' with Markov chains. After repeated 'repeatable' events, it is able to generate more of those repeatable events that follow a similar frequency pattern. Useful for things like generating English-looking random text or making the best chess move after training across chess game histories.
Interface implementation locator
Fetches all current-assembly implementations of a given interface dynamically without needing full-blown IOC containers.
A mobbing or meeting timer (also fine for Pomodoro) for the Windows desktop. There is also a direct download from the latest Release build within the repository.
Filesystem change checker
A polling-based alternative to the .Net framework's file watchers - this isn’t subject to the double-hit issues caused by programs like Notepad hitting a file twice (once for the content, then again for the file attributes).
