+# Sample using agents with streaming in Azure.AI.Agents
+
+In this example we will demonstrate the agent streaming support.
+
+1. First we need to create agent client and read the environment variables that will be used in the next steps.
+```C# Snippet:AgentsStreamingAsync_CreateClient
+var projectEndpoint = configuration["ProjectEndpoint"];
+var modelDeploymentName = configuration["ModelDeploymentName"];
+PersistentAgentsClient client = new(new Uri(projectEndpoint), new DefaultAzureCredential());
+```
+2. We will create agent with the Interpreter tool support. It is needed to allow fow writing mathematical formulas in [LaTeX](https://en.wikipedia.org/wiki/LaTeX) format.
+
+Synchronous sample:
+```C# Snippet:AgentsStreaming_CreateAgent
+PersistentAgent agent = client.CreateAgent(
+    model: modelDeploymentName,
+    name: "My Friendly Test Agent",
+    instructions: "You politely help with math questions. Use the code interpreter tool when asked to visualize numbers.",
+    tools: [new CodeInterpreterToolDefinition()]
+);
+```
+
+Asynchronous sample:
+```C# Snippet:AgentsStreamingAsync_CreateAgent
+PersistentAgent agent = await client.CreateAgentAsync(
+    model: modelDeploymentName,
+    name: "My Friendly Test Agent",
+    instructions: "You politely help with math questions. Use the code interpreter tool when asked to visualize numbers.",
+    tools: [new CodeInterpreterToolDefinition()]
+);
+```
+
+3. Create `Thread` with the message.
+
+Synchronous sample:
+```C# Snippet:AgentsStreaming_CreateThread
+PersistentAgentThread thread = client.CreateThread();
+
+client.CreateMessage(
+    thread.Id,
+    MessageRole.User,
+    "Hi, Agent! Draw a graph for a line with a slope of 4 and y-intercept of 9.");
+```
+
+Asynchronous sample:
+```C# Snippet:AgentsStreamingAsync_CreateThread
+PersistentAgentThread thread = await client.CreateThreadAsync();
+
+await client.CreateMessageAsync(
+    thread.Id,
+    MessageRole.User,
+    "Hi, Agent! Draw a graph for a line with a slope of 4 and y-intercept of 9.");
+```
+
+4. Read the output from the stream.
+
+Synchronous sample:
+```C# Snippet:AgentsStreaming_StreamLoop
+foreach (StreamingUpdate streamingUpdate in client.CreateRunStreaming(thread.Id, agent.Id))
+{
+    if (streamingUpdate is MessageContentUpdate contentUpdate)
+    {
+        Console.Write(contentUpdate?.Text);
+        if (contentUpdate?.ImageFileId is not null)
+        {
+            Console.WriteLine($"[Image content file ID: {contentUpdate.ImageFileId}");
+            Console.WriteLine();
+        }
+    }
+}
+```
+
+Asynchronous sample:
+```C# Snippet:AgentsStreamingAsync_StreamLoop
+await foreach (StreamingUpdate streamingUpdate in client.CreateRunStreamingAsync(thread.Id, agent.Id))
+{
+    if (streamingUpdate is MessageContentUpdate contentUpdate)
+    {
+        Console.Write(contentUpdate?.Text);
+        if (contentUpdate?.ImageFileId is not null)
+        {
+            Console.WriteLine($"[Image content file ID: {contentUpdate.ImageFileId}");
+            Console.WriteLine();
+        }
+    }
+}
+```
+
+5. Finally, we delete all the resources, we have created in this sample.
+
+Synchronous sample:
+```C# Snippet:AgentsStreaming_Cleanup
+client.DeleteThread(thread.Id);
+client.DeleteAgent(agent.Id);
+```
+
+Asynchronous sample:
+```C# Snippet:AgentsStreamingAsync_Cleanup
+await client.DeleteThreadAsync(thread.Id);
+await client.DeleteAgentAsync(agent.Id);
+```
