.NET on Heroku: Now Generally Available

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. We want to thank our beta users for their invaluable feedback, which has helped us to refine and enhance the .NET experience on Heroku.

Key Benefits of .NET GA

With General Availability, .NET applications on Heroku are fully supported in production environments. This represents our long-term commitment to the .NET ecosystem, meaning you can rely on Heroku's robust infrastructure and support services for your critical .NET workloads.

.NET joins as our 7th runtime ecosystem on the Heroku platform. Like all of our other ecosystems, what this means for .NET developers:

• You'll have access to the latest stable version of the .NET runtime the day it’s released.
• Comprehensive documentation is available on the Heroku Dev Center, tailored specifically for .NET developers.
• Our support team is here to help with your .NET deployments, and you’re covered by Heroku’s support policy.
• You'll have a developer experience that feels native and follows idioms familiar to .NET developers.

General Availability signifies that .NET on Heroku is production-ready, fully supported, and seamlessly integrated into the Heroku ecosystem, providing .NET developers with a first-class experience.

Built for .NET

Heroku now supports .NET, including languages like C#, F#, and Visual Basic. Heroku automatically understands, builds, and deploys your .NET applications, applying smart defaults to simplify your workflow. However, if you need more control, you can easily override these defaults to tailor the environment to your specific requirements, ensuring you can focus on coding and innovation.

.NET on Heroku includes:

• The most recent .NET SDK and runtimes are installed automatically based on your project’s TargetFramework. You can override that using a global.json file if needed.
• ASP.NET Core apps are configured to listen on the right port by default. All executable project types, including Console and Worker Services, are detected during build. The build log shows helpful output that can easily be adapted to your own process types with Procfile for more control.
• Heroku supports framework-dependent apps by default, allowing a solution with many projects to be efficiently supported. Other deployment models, such as self-contained, ReadyToRun, and highly optimized Native AOT, are also supported out of the box.

Whether you’re working with a single project or a solution that includes multiple apps, Heroku adapts to your setup in a way that feels intuitive and natural for .NET developers.

Stay in the Flow

Beyond the core support, .NET apps plug right into the developer workflow you expect.

• Use Heroku Pipelines to manage staging and production environments.
• Run tests automatically with Heroku CI, supporting any major .NET testing framework.
• Preview pull requests with Review Apps - complete, disposable Heroku apps that spin up automatically for each GitHub PR.
• Automate tasks like database migrations with Release Phase, scale dynos instantly as demand grows, and roll back to any previously released version if something goes wrong.

With Heroku, you get a smooth, automated, and collaborative .NET development experience, allowing you to release with confidence from coding to production.
