+## .NET 中的服务发现
+
+服务发现是一种用于发现和定位服务的机制，它可以帮助客户端找到服务的位置和地址。服务发现可以用于构建和设计微服务架构中的 API 网关，以便客户端可以通过 API 网关访问后端服务。
+
+## 使用服务发现
+
+https://learn.microsoft.com/zh-cn/dotnet/core/extensions/service-discovery
+
+```shell
+dotnet add package Microsoft.Extensions.ServiceDiscovery --prerelease
+```
+
+```csharp
+builder.Services.AddServiceDiscovery();
+
+builder.Services.ConfigureHttpClientDefaults(static http =>
+{
+    // Turn on service discovery by default
+    http.AddServiceDiscovery();
+});
+```
+
+```json
