 The following example demonstrates a web availability test that requires a simple URL ping using the `getStringAsync()` method.
 
-    ```csharp
-    using System.Net.Http; 
-
-    public async static Task RunAvailabilityTestAsync(ILogger log) 
-    { 
-        using (var httpClient = new HttpClient()) 
-        { 
-            // TODO: Replace with your business logic 
-            await httpClient.GetStringAsync("https://www.bing.com/"); 
-        } 
-    } 
-    ```

+    {
+        // TODO: Replace with your business logic
+        await httpClient.GetStringAsync("https://www.bing.com/");
+    }
+}
+```
 
 For advanced scenarios where the business logic must be adjusted to access the URL, such as obtaining tokens, setting parameters, and other test cases, custom code is necessary.
