 ASP.NET Core now supports returning a [ServerSentEvents](xref:System.Net.ServerSentEvents) result using the [TypedResults.ServerSentEvents](https://source.dot.net/#Microsoft.AspNetCore.Http.Results/TypedResults.cs,051e6796e1492f84) API. This feature is supported in both Minimal APIs and controller-based apps.
 
-Server-Sent Events is a server push technology that allows a server to send a stream of event messages to a client over a single HTTP connection. In .NET the event messages are represented as [`SseItem<T`>`](/dotnet/api/system.net.serversentevents.sseitem-1) objects, which may contain an event type, an ID, and a data payload of type `T`.

 The [TypedResults](xref:Microsoft.AspNetCore.Http.TypedResults) class has a new static method called [ServerSentEvents](https://source.dot.net/#Microsoft.AspNetCore.Http.Results/TypedResults.cs,ceb980606eb9e295) that can be used to return a `ServerSentEvents` result. The first parameter to this method is an `IAsyncEnumerable<SseItem<T>>` that represents the stream of event messages to be sent to the client.
