Latest update to Microsoft’s cloud-native application framework allows developers to define an entire distributed application in a single apphost.cs file.
Microsoft is attempting to improve the developer experience for those building distributed applications with the latest updates to Aspire, a collection of tools, templates, and packages for building such apps.
.NET Aspire 9.5 has been released with a number of improvements to the dashboard. It also adds targeted CLI and tooling updates, channel-aware templating, and a preview of infrastructure for .NET 10's new file-based apps feature.
Microsoft released .NET Aspire 9.5 with a single-file AppHost option, a new Generative AI Visualizer, expanded integrations for GitHub Models, Azure AI Foundry, and OpenAI, along with lifecycle and logging improvements for distributed cloud-native .NET applications.
Last week, Microsoft announced the release of .NET 10 RC 1, the first of two release candidates ahead of the final version. As stated by the .NET team, this build comes with a go-live license, allowing developers to use it in production environments with official support. It is available alongside Visual Studio 2026 Insiders and is supported in Visual Studio Code through the C# Dev Kit.
.NET Aspire orchestration simplifies building distributed applications by providing a unified model for defining, managing, and connecting services. It automates dependency wiring, configures environments, and offers built-in observability. Ideal for local development and preparing apps for cloud deployment, Aspire streamlines the developer experience with code-first configuration and standardized integrations, making multi-service apps easier to manage and debug.
.NET Aspire simplifies cloud-native .NET 8 development with orchestration, telemetry, and pre-configured service defaults. Build distributed apps faster using templates, a developer dashboard, and flexible deployment options for Azure, Kubernetes, and more. Focus on code, not infrastructure, with this innovative framework.
Let's take a step back and talk about why .NET Aspire is relevant to today's developers, why they should care, and how to take an existing app and Aspire it.
