A .NET port of java-string-similarity.

A .NET dynamic fake library for creating all types of fake objects, mocks, stubs etc.

Fast deep cloning library, supporting anything from .NET 4.6 to modern .NET 8+. Implements both deep and shallow cloning. Extensively tested, focused on performance and stability even on complicated object graphs. FastCloner is designed to work with as few gotchas as possible out of the box. The mapping is zero-config by default. Clone your objects and be done with it fast. FastCloner builds upon DeepClone.

// Init (only for mapping)
CsvParser.RegisterAssembly<Program>();

// Use
var parser = new CsvParser(filecontent);
var header = parser.ReadHeader();
// or parser.ReadHeader<HeaderModel>()
var entries = parser.ReadBodyAndMap<MyModel>();
// or without mapping (fastest): var entries = parser.ReadBody();

ASP.NET Minimal APIs Made Easy...

FastEndpoints is a developer friendly alternative to Minimal APIs & MVC

It nudges you towards the REPR Design Pattern (Request-Endpoint-Response) for convenient & maintainable endpoint creation with virtually no boilerplate.

Performance is on par with Minimal APIs. It's faster, uses less memory and does around 35k more requests per second than a MVC Controller in our benchmarks.

Fastenshtein is one of the fastest .Net Levenshtein projects around. Levenshtein calculates the shortest possible distance between two strings. Producing a count of the number of insertions, deletions and substitutions to make one string into another.

Fastenshtein is an optimized and fully unit tested Levenshtein implementation. It is optimized for speed and memory usage.

FastEnum is the fastest enum utilities for C#/.NET. It's much faster than .NET Core, and also faster than Enums.NET that is similar library. Provided methods are all achieved zero allocation and are designed easy to use like System.Enum. This library is quite useful to significantly improve your performance because enum is really popular feature.

In .NET reflection is slow... well, kinda slow. If you need access to the members of an arbitrary type, with the type and member-names known only at runtime - then it is frankly hard (especially for DLR types). This library makes such access easy and fast.
