As an open source enthusiast and a .NET developer I’ve been watching the transformation of Microsoft happen and it has been great to watch. You see I’m an avid user of DotNetNuke and if you know anything about DNN’s history you know that DNN was one of the earliest, if not the earliest, open source project in the .NET Ecosystem. From 2003 on DNN has been a pioneer in the .NET open source world. A lot has happened and several trends have come and gone in the Microsoft world since 2003. As an open source project built on Microsoft technology the notion of being open source wasn’t always a popular conversation topic. Being open source wasn’t “cool” and sometimes negative perceptions about open source solutions were visible. Boy have times changed! Microsoft is Serious About Open Source… and It’s Not Just Lip Service One of my college football coaches always said “ Your words don’t mean anything, but your actions mean everything .” Actions are a really good sign of what someone really believes.Microsoft’s strategic shift to embracing and focusing on open source over the past few years has been such a refreshing transition to see, feel, and experience for me and my fellow DNN’ers because of the actions we are seeing. If we look at the recent and strategic moves Microsoft has made it’s easy to see that Microsoft is indeed serious about open source. If you aren’t convinced that Microsoft is serious about open source or if you are not keeping up, let’s look at some of the actions Microsoft has taken related to open source. And these are just the ones I have observed… I’m sure there is even more evidence out there. Open Sourcing of .NET Core - One of the recent Microsoft technologies in the web world is .NET Core . .NET Core is a cross-platform, open source, re-implementation of the .NET Framework and it offers some great features. Releasing .NET Core as open source was a major sign that Microsoft is serious about open source. .NET Foundation Providing Resources For OSS Projects - The .NET Foundation is not technically owned by Microsoft, but it is led by very well recognized names in the Microsoft ecosystem. The .NET Foundation fosters and facilitates open source by providing resources to projects within the foundation. You can find a full list of the resources on the .NET Foundation website and you can see how we in the DNN Community benefit from these resources in my recent blog “ 5 Reasons We’re Glad to Be Part of the .NET Foundation ”. Buying GitHub - In buying GitHub not only did Microsoft make a strategic purchase, but it reiterated the commitment to open source as GitHub is the world’s most popular place for open source. Strategic Position of .NET Open/Source Booth at Build & MS Ignite - I helped out with the .NET Open Source booth in the Expo area at Microsoft’s Build conference and at the recent MS Ignite conference. With all the amazing new technologies and top notch vendors one may think the open source booth would be somewhere stuck in a back corner. Quite the contrary, the .NET Open Source booth was dead in the middle of the action at both events. At MS Ignite, if you came to the expo there’s a high percentage chance you saw the open source booth. This strategic positioning and messaging from Microsoft to developers and IT Pros was simple - Open Source is important to us. Open Sourcing Patent / Joining ION - In another bold move Microsoft open-sourced it’s patent portfolio . OIN (Open Invention Network) is an open source patent consortium and Microsoft just brought 60,000 patents to it. This move is a big one and protects open source projects from patent lawsuits. Here again the messaging is clear, we are serious about open source. Why It’s a Great Time to Be a .NET Developer There has never been a better time to be a .NET Developer. Literally everything you need to get started building is online and free to use and even better it’s likely open source. Anybody, anywhere can download code, look at it, enhance it, modify it, and submit it back to the projects if desired. If you can dream it, you can build it and you may build an online team of users and contributors to assist you in the process. Microsoft is literally making it easy to build open source projects via the technologies and resources they are providing. They are removing roadblocks for developers and being 100% transparent. Consider the following capabilities anybody, anywhere has... Want to collaborate on a project - Create a GitHub account and get going Find a bug - Make a pull request Need help - Connect with the developers working on the project or in the open source community Got a Popular OSS project - Join the .NET Foundation Worried about transparency - Everything is developed in the open In Conclusion I referenced one of my college football coaches earlier, but he wasn’t the only one to to impart wisdom during my athletic days. My high school coaches had more one-liners than anyone could remember. One line that stuck with me was “If you do the little things, the big things will take care of themselves.” Microsoft is not only doing the big things, but they are also doing the little things that continue to reinforce their seriousness about open source. We are watching a culture and paradigm shift occur in real-time and it’s awesome. By going “all in” on open source Microsoft is not only winning the hearts of developers, but they are making it easy for developers to get started with their technologies! I think the strategic decision to embrace open source will have a big impact for Microsoft in the long term.
