Six months after its first preview released during .NET Conf 2023, .NET Aspire becomes generally available (GA) at Microsoft Build 2024. This project, which aims to revolutionize the local development of distributed applications, has unfortunately been overlooked by some due to its preview status. This is good news for those who can now embark on the adventure. Here are some resources to learn how to use .NET Aspire.
