Decoding .NET8: Unveiling Cloud-Native Observability - OpenObservability Talks S4E09

The .NET programming language is taking cloud native deployment and observability seriously, and most notably with the recent announcement of .NET Aspire stack unveiled at the recent .NET Conf 2023. 

In this episode, we reviewed the open source maintainers’ journey to making .NET a "by default, out of the box observable platform", as ASP.NET Core creator David Fowler put it. David was this episode’s guest, and with him we dived into .NET Aspire and how it simplifies the complexities of cloud app development with capabilities around service discovery, observability, and resilience. We discussed the local developer experience, the path to developer observability, and what we can expect from the upcoming GA release of .NET8.

David Fowler has been at Microsoft for 15 years working on developer frameworks and tools in the .NET space. He's one of the creators of several popular OSS frameworks and tools such as NuGet, SignalR and ASP.NET Core, and also architected the Azure SignalR Service. Originally from Barbados, he's an avid open-source advocate and developer currently focused on simplifying developer experiences in the microservice space.
