SignalR makes it easy to add real-time functionality to .NET web applications—things like live chat, instant notifications, or interactive dashboards. But what happens when your app starts to grow? A single server can only take you so far. At some point, you’ll need to scale out. In this post, we’ll walk through what it takes to scale a SignalR app to run across multiple servers. We’ll start with the basics, then show you how to use Redis as a backplane and enable sticky sessions to k...| Heroku
In a short amount of time, AI has transformed life, work, and how we think about the future. These rapid advancements have left many of us wondering how to integrate AI into our existing workflows and what it means for the future of app development. The apps we're building today are more than lines of code; they're becoming dynamic, intelligent, and increasingly autonomous. To navigate this new landscape, we need to bring our current skills and technology into this AI-driven future. As part o...| Heroku
It's never been a more exciting time to be a .NET developer. With .NET (formerly known as .NET Core) approaching its 10-year anniversary this November , the platform has evolved into a powerful, cross-platform ecosystem, embracing modern development practices and powering a vast array of applications. Today, we're thrilled to announce that .NET support on Heroku, previously in beta , is now Generally Available (GA), marking a significant milestone for .NET developers on our platform.
