Heroku Support for .NET 10 LTS: What Developers Need to Know

It’s that time of year for .NET when we get a new major version and a bunch of exciting features. .NET Conf 2025 kicked off earlier today, bringing with it the release of .NET 10, as well as ASP.NET Core 10, C# 14, and F# 10. Congrats (and a big thank you) to the .NET team and everyone who helped get .NET 10 out the door.

At Heroku, we believe you should be able to use language and framework releases when they launch, and we prepare accordingly. You can now build and run .NET 10 apps on Heroku, with buildpack support for new SDK features like file-based apps, .slnx solution files, and more.

Heroku: Powering the Next Wave of Apps with AI

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 …

Heroku Fir: Dive into the New Platform Capabilities

For years, Heroku has been empowering developers to deploy and scale their applications with ease. Now, we’re thrilled to introduce the general availability of the next generation of the Heroku platform, codenamed Fir, launching later this month April 2025. Built on open source standards and cloud-native technologies, Fir accelerates your development like never before.

The Next Generation of the Heroku Platform

Over the past year, Heroku has been on a journey of reflection as we rebase the platform to address the changing needs of app teams toward the future without disrupting your business. In the Heroku way, we want to be thoughtful about your experience as we evolve.

When we started Heroku, it was the early days of cloud computing, before Docker and Kubernetes were household names in IT. We launched Heroku (and the platform-as-a-service category) to help teams get to the cloud easily with an elegant user experience in front of a powerful platform that automated a lot of the manual work that slowed teams down. To do that then, we had to build a lot of the tooling ourselves, like orchestration and self-hosting the databases in AWS. ‌The platform delivered customers the outcomes they needed to deploy apps quickly and scale effortlessly in the cloud‌—all without having to worry about how the platform worked.

.NET Support on Heroku

We’re excited to announce that official support for .NET on Heroku is entering public beta starting today. Developers can now build and deploy applications in C#, F#, and Visual Basic, using frameworks like ASP.NET Core and Blazor, all with the simplicity and flexibility of the Heroku platform.

.NET has long been one of the most requested frameworks to join Heroku’s lineup, and for good reason. Known for its power and versatility .NET enables developers to build everything from high-performance APIs to complex, full-stack web applications and scalable microservices. Now, developers can combine .NET’s capabilities with Heroku’s streamlined platform for a first-class developer experience.

Planting New Platform Roots in Cloud Native with Fir

Cloud platforms have come a long way since Heroku first set out to empower developers. Today’s cloud native development demands even greater flexibility, openness, and scalability. A fun fact about Heroku is that we use trees to denote the generation of the platform technology stack (aka version). In the tradition of Aspen, Bamboo, and Cedar, we are introducing Fir, the latest Heroku technology stack built on open source standards and cloud native technologies.

When we …
