The announcement highlights the preview release of the Elastic APM .NET agent, designed to collect user feedback and demonstrate progress within the community. This agent, part of the Elastic Application Performance Monitoring solution, provides insights into application performance, error tracking, and end-user browser experience, and is available for various programming languages, including Java, Node.js, Python, Ruby, JavaScript/RUM, and Go. The preview version features auto-instrumentation for ASP.NET Core 2.x, Entity Framework Core 2.x, and outgoing web requests via the HttpClient class on .NET Core, and offers a Public Agent API for manual instrumentation on other frameworks. Distributed as NuGet packages, it includes Elastic.Apm.All, Elastic.Apm, Elastic.Apm.AspNetCore, and Elastic.Apm.EntityFrameworkCore packages, with the ability to configure the agent using environment variables or the IConfiguration interface. Users are encouraged to provide feedback through discussion forums or GitHub, with the understanding that the release is subject to changes based on community input and ongoing development, which may include features like distributed tracing and support for ASP.NET Classic.
