Top 23 C# Misc Projects

Polly
Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+.
This is probably one of the most useful "cloud" patterns out there and it is fairly easy to implement. There are great articles and implementations, like Polly, already on the internet about this pattern so why another one?

Coravel
Near-zero config .NET library that makes advanced application features like Task Scheduling, Caching, Queuing, Event Broadcasting, and more a breeze!
In the .NET ecosystem, there are a few great libraries for scheduling or queuing background work. I created Coravel as an easy way to build .NET applications with more advanced web application features. But it's mostly known as a background job scheduling library.

-
Hashids.net
A small .NET package to generate YouTube-like hashes from one or many numbers. Use hashids when you do not want to expose your database ids to the user.
-
This seems to be a pretty straightforward GUI wrapper around https://github.com/Tyrrrz/YoutubeExplode and https://github.com/AydinAdn/MediaToolkit (see https://github.com/PackJC/YoutubeToMP3/blob/main/Form1.cs). Note the (admirable but non-OSI) terms of the former library if using any outputs from this software.
https://github.com/yt-dlp/yt-dlp is a well-maintained public domain alternative.

Scientist.net
A .NET library for carefully refactoring critical paths. It's a port of GitHub's Ruby Scientist library
-
WorkflowEngine
WorkflowEngine.NET - component that adds workflow in your application. It can be fully integrated into your application, or be in the form of a specific service (such as a web service).
Project mention: FormEngine Alternative: A Comprehensive Comparison with SurveyJS | dev.to | 2024-08-01Its worth noting the Optimajet also sell a a product called 'WorkflowEngine', which you can use to process your data. That being said there is no native integration between WorkflowEngine and FormEngine and it is a separate product with an additional cost which is why I have not included it in this comparison.

-
DeviceId
A simple library providing functionality to generate a 'device ID' that can be used to uniquely identify a computer.
-
-
-
HidLibrary
This library enables you to enumerate and communicate with Hid compatible USB devices in .NET.
-
ByteSize
ByteSize is a utility class that makes byte size representation in code easier by removing ambiguity of the value being represented. ByteSize is to bytes what System.TimeSpan is to time.
The ContentLength is in bytes, so if you want to display it to the user, you might want to use a NuGet package like ByteSize or similar to get a user friendly string.
