Dennis Doomen returns to the podcast to talk with us about open source projects. We discuss some of the latest milestones for Fluent Assertions and some of the positives and negatives of managing a popular open source project. While companies and developers benefit from open source projects they don't always view the open source community the same way. Dennis shares his thoughts on the subject and Shawn and Caleb talk about how their companies use open source. We also talk about different ways to sponsor an open source project and some of the communities that can grow up around an open source project. What do you think about open source? Have you contributed to an open source project either financially or by adding to the project directly? Let us know on Twitter at @dotnet_Podcast.
