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’s commitment to developer productivity shines through in its powerful buildpack system. They handle the heavy lifting of building your app, letting you focus on what matters most: writing code. A prime example is the Heroku Java buildpack, a versatile tool that simplifies deploying Java applications, especially those built with popular frameworks like Spring Boot, Quarkus, and Micronaut.
One of the core strengths of Heroku buildpacks is their automatic nature. They intelligently detect your application’s language and framework, fetching the necessary build tools and configuring the Heroku platform to run your app seamlessly. This means no more wrestling with server configurations or deployment scripts – Heroku handles it all.

When we open-sourced buildpacks nearly seven years ago, we knew they would simplify the application deployment process. After a developer runs git push heroku master, a buildpack ensures the application’s dependencies and compilation steps are taken care of as part of the deploy.
As previously announced, we’ve taken the same philosophies that made buildpacks so successful and applied them towards creating Cloud Native Buildpacks (CNB), a standard for turning source code into Docker images without the need for Dockerfiles. In this post, we’ll take a look at how CNBs work, how they aim to solve many of the problems that exist with Dockerfile, and how you can use them with the recent beta release of the buildpacks.io project. As part of this release, we’ve created a Heroku buildpacks builder image for Ruby, Node.js, Java, Python, PHP, and Go that works with the CNB tooling.

Progressive web apps (or PWAs) enable websites to function more like native mobile apps in exchange for some flexibility. You get cross-platform native mobile app functionality (or close to it) without all the overhead of app store approvals and tons of platform-specific native code.
Users can install a progressive web app to their home screen and launch it just like a native app. However, …
