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.

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.

Flow is an important part of software development. The ability to achieve flow during daily work makes software development a uniquely enjoyable profession. Interruptions in your code/test loop make this state harder to achieve. Whether you are running unit tests locally, launching a local webserver, or deploying to Heroku there's always some waiting and some interruption. Every second saved helps you stay in your flow.

We’ve been working on reducing the time it takes to build your code on Heroku. Read through this post for details on the process we used to make builds fast, or check out the end result from the graph below:

Let's take a look at our process in delivering these...
