Summary
Microsoft has released Aspire 13.4, with the key feature being general availability of the TypeScript AppHost, as well as new integrations for Go, Bun, Blazor and WebAssembly. The company currently describes Aspire as a "code-first orchestration and observability layer for distributed applications" which makes it sound like some kind of service, but it is not. Aspire can also deploy applications, though it is not a service that runs in production. NET variant is a C# project and for TypeScript, a code file called apphost.mts which imports an Aspire module.
