OSS Power‑Ups
.NET Edition

Each month we will offer our special power-up treatment to a new project in the .NET community. Check out the latest episode of our series or watch them all:

Previous Guests

FluentValidation

A library for building strongly-typed validation rules, with amazing popularity, and over 50 million downloads. Jeremy Skinner will help us get started with some basic examples, writing custom validators, localizing error messages, and ASP.NET Core integration. Also, find out about the FluentValidation plugin that we've created!

FluentAssertions

An extensive set of extension methods that allows you to more naturally specify the expected outcome of TDD or BDD-styled unit tests. Dennis Doomen will be showing how Fluent Assertions is not just an assertion library, but a crucial ingredient for writing intention-revealing unit tests. Also, find out about the FluentAssertions plugin that we've created!

Snoop

The Swiss army knife when it comes to analyzing and dissecting WPF UI. Bastian Schmidt will give us an introduction and show all the tricks including how to diagnose view binding errors and other common mistakes in WPF, troubleshoot events and find out where they are handled, preview and zoom parts of the UI (even in 3D), and much more.

Silk.NET

A high-performance, low-level wrapper over many native libraries and is your one-stop-shop for .NET graphics and compute workloads. Being used in a number of games and game engines, it aims to be the one library you need for .NET multimedia, graphics, and high-grade compute applications. Dylan Perks and Kai Jellinghaus will show how Silk.NET works in practice and what sets it apart from other libraries.

SpecFlow

A tool to bring Behavior-Driven Development to .NET by providing a mechanism that turns specifications into executable code. Andreas Willich will help us get started with BDD and SpecFlow. We will have a look at how to write your first scenarios for applications and automate them with various different other .NET libraries, like RestSharp, Selenium, or FluentAssertions.

Verify

A snapshot tool that enables the assertion of complex data models and documents. Simon Cropp introduces us to Verify, which can be called on test results during the assertion phase in any major test framework. Verify serializes the results and stores them in so-called snapshot files. On the next test execution, the new results are compared to the previously accepted snapshots. Also, find out about the Verify plugin that we've created!

Supporting the .NET open-source ecosystem

Many projects already use our open-source license program. With this initiative, we want to go way further and give hand-picked projects a major boost!

GitHub Sponsorship

We will sponsor our maintainers with $100 per month for a full year on GitHub Sponsors.

Raise Awareness

We want to give maintainers a platform to talk about their projects and ways of contribution. This can be a webinar, blog post, or interview.

Share Strengths

Our advocacy team would like to share its personal strengths in memory profiling, graphics creation, build pipelines, and plugin development.

Contributed Plugins for ReSharper and Rider

Whenever a project allows developing additional IDE features around it and time permitting, we will build dedicated support plugins that are available from our plugin marketplace:

More Background

In one of our JetBrains Connect episodes, Paul Everitt talks to Aaron Stannard and Rachel Appel about the problems that OSS projects face today.
