Update openapi-spec-samples.md

Switching to use PersistentThreadMessage openApiAuthentication on OpenApiToolDefinition. Some of the prior changes were reverted so added them back in with the comments from previous version.

 First, retrieve configuration details and create a `PersistentAgentsClient`, then define the `OpenApiToolDefinition` using the OpenAPI specification.
 
 ```csharp
-    var projectEndpoint = configuration["ProjectEndpoint"];
-    var modelDeploymentName = configuration["ModelDeploymentName"];
-    var openApiSpec = configuration["OpenApiSpec"];
-    PersistentAgentsClient client = new(new Uri(projectEndpoint), new DefaultAzureCredential());
-  
-    // Helper function to get the absolute path to the OpenAPI spec file
-    private static string GetFile([CallerFilePath] string pth = "")
-    {
-        var dirName = Path.GetDirectoryName(pth) ?? "";
-        return Path.Combine(dirName, "weather_openapi.json");
-    }
-    
-    var spec = BinaryData.FromBytes(File.ReadAllBytes(openApiSpec));
-     // Using anonymous auth for this example
-    OpenApiAnonymousAuthDetails openApiAnonAuth = new();
-    // Define the OpenAPI tool
-    OpenApiToolDefinition openApiTool = new(
-        name: "get_weather", 
-        description: "Retrieve weather information for a location", 
-        spec: spec, 
-        auth: openApiAnonAuth, 
-        defaultParams: ["format"] 
-    );

+IConfigurationRoot configuration = new ConfigurationBuilder()
+    .SetBasePath(AppContext.BaseDirectory)
+    .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
+    .Build();
+

+    description: "Retrieve weather information for a location",
+    spec: spec,
+    openApiAuthentication: openApiAnonAuth,
+    defaultParams: ["format"]
+);
 ```
 
 ## Create an agent
 Next, create a `PersistentAgent` with the necessary model deployment, name, instructions, and the previously defined OpenAPI tool.
 
 ```csharp
-    PersistentAgent agent = client.CreateAgent(
-        model: modelDeploymentName,
-        name: "Open API Tool Calling Agent",
-        instructions: "You are a helpful agent.",
-        tools: [openApiTool]
-    );
+PersistentAgent agent = client.Administration.CreateAgent(
+    model: modelDeploymentName,
+    name: "Open API Tool Calling Agent",
+    instructions: "You are a helpful agent.",
+    tools: [openApiToolDef]
+);
 ```
 
 ## Create thread, message, and run
 Create a `PersistentAgentThread` for the conversation, add a user message to it, and then create a `ThreadRun` to process the message, waiting for its completion.
 
 ```csharp
-    PersistentAgentThread thread = client.CreateThread();
-    ThreadMessage message = client.CreateMessage(
-        thread.Id,
-        MessageRole.User,
-        "What's the weather in Seattle?");
-    
-    ThreadRun run = client.CreateRun(thread, agent);
-    
-    // Poll for the run's completion status
-    do
-    {
-        Thread.Sleep(TimeSpan.FromMilliseconds(500));
-        run = client.GetRun(thread.Id, run.Id);
-    }
-    while (run.Status == RunStatus.Queued
-        || run.Status == RunStatus.InProgress
-        || run.Status == RunStatus.RequiresAction);
+PersistentAgentThread thread = client.Threads.CreateThread();
+
+client.Messages.CreateMessage(
+    thread.Id,
+    MessageRole.User,
+    "What's the weather in Seattle?");
+
+ThreadRun run = client.Runs.CreateRun(
+    thread.Id,
+    agent.Id);
+
+// Poll for the run's completion status
+do
+{
+    Thread.Sleep(TimeSpan.FromMilliseconds(500));
+    run = client.Runs.GetRun(thread.Id, run.Id);
+}
+while (run.Status == RunStatus.Queued
+    || run.Status == RunStatus.InProgress
+    || run.Status == RunStatus.RequiresAction);
 ```
 
 ## Display conversation messages
 Retrieve and print all messages from the thread to the console in chronological order to display the conversation flow.
 
 ```csharp
-    Pageable<ThreadMessage> messages = client.Messages.GetMessages(
-        threadId: thread.Id, 
-        order: ListSortOrder.Ascending 
-    );
+Pageable<PersistentThreadMessage> messages = client.Messages.GetMessages(
+    threadId: thread.Id,
+    order: ListSortOrder.Ascending);
 
-    foreach (ThreadMessage threadMessage in messages)
+foreach (PersistentThreadMessage threadMessage in messages)
+{
+    foreach (MessageContent content in threadMessage.ContentItems)
     {
-        foreach (MessageContent content in threadMessage.ContentItems)
+        switch (content)
         {
-            switch (content)
-            {
-                case MessageTextContent textItem:
-                    Console.WriteLine($"[{threadMessage.Role}]: {textItem.Text}");
-                    break;
-            }
+            case MessageTextContent textItem:
+                Console.WriteLine($"[{threadMessage.Role}]: {textItem.Text}");
+                break;
         }
     }
+
 ```
 
 ## Clean up resources
 Finally, delete the created `PersistentAgentThread` and `PersistentAgent` to clean up the resources used in this example.
 
 ```csharp
-    client.DeleteThread(thread.Id);
-    client.DeleteAgent(agent.Id);
+client.Threads.DeleteThread(thread.Id);
+client.Administration.DeleteAgent(agent.Id);
 ```
