+
+Use `GetApplicationResponseAsync` to call an application.
+
+Use `GetApplicationResponseStreamAsync` for streaming output.
+
+```csharp
+var request =
+    new ApplicationRequest()
+    {
+        Input = new ApplicationInput() { Prompt = "Summarize this file." },
+        Parameters = new ApplicationParameters()

+    };
+var response = await client.GetApplicationResponseAsync("your-application-id", request);
+Console.WriteLine(response.Output.Text);
+```
+
+`ApplicationRequest` use an `Dictionary<string, object?>` as `BizParams` by default.
+
+```csharp
+var request =
+    new ApplicationRequest()
+    {
+        Input = new ApplicationInput()
+        {
+            Prompt = "Summarize this file.",

+        }
+    };
+var response = await client.GetApplicationResponseAsync("your-application-id", request);
+Console.WriteLine(response.Output.Text);
+```
+
+You can use the generic version `ApplicationRequest<TBizParams>` for strong-typed `BizParams`. But keep in mind that client use `snake_case` by default when doing json serialization, you may need to use `[JsonPropertyName("camelCase")]` for other type of naming policy.
+
+```csharp
+public record TestApplicationBizParam(
+    [property: JsonPropertyName("sourceCode")]

+
+`ApplicationRequest` 默认使用 `Dictionary<string, object?>` 作为 `BizParams` 的类型。
+
+```csharp
+var request =
+    new ApplicationRequest()
+    {
+        Input = new ApplicationInput()
+        {
+            Prompt = "Summarize this file.",
+            BizParams = new Dictionary<string, object?>()
+            {
+                { "customKey1", "custom-value" }
+            }
+        }
+    };
+var response = await client.GetApplicationResponseAsync("your-application-id", request);
+Console.WriteLine(response.Output.Text);
+```
+
+如需强类型支持，可以使用泛型类 `ApplicationRequest<TBizParams>`。
+注意 SDK 在 JSON 序列化时使用 `snake_case`。如果你的应用采用其他的命名规则，请使用 `[JsonPropertyName("camelCase")]` 来手动指定序列化时的属性名称。
+
+```csharp
+public record TestApplicationBizParam(
+    [property: JsonPropertyName("sourceCode")]
+    string SourceCode);
+
+var request =
+    new ApplicationRequest<TestApplicationBizParam>()

+        {
+            Prompt = "Summarize this file.",
+            BizParams = new TestApplicationBizParam("test")
+        }
+    };
+var response = await client.GetApplicationResponseAsync("your-application-id", request);
