Avalonia UI Real World (Kestrel to Avalonia Comms) **[AngelSix](https://daily.dev/sources/angelsix)** · 27 min read · 0 upvotes · 0 comments ## Summary A hands-on coding walkthrough builds communication between a Kestrel web server and an Avalonia desktop UI running in the same .NET process. The author wires up Microsoft.Extensions.DependencyInjection by sharing the WebApplication's service collection, exposes the view model to Kestrel endpoints via [FromServices], and tests two-way data updates between the web endpoint and the UI thread. The session then introduces a SolidWorks batch process host service that reads files from a folder to simulate real SolidWorks file access, binds the results to an Avalonia ListBox, and ends by planning to extract shared API classes into a core project so both apps can expose REST endpoints over the dependency-injected services. ## Full article daily.dev links to this article rather than hosting it.
