Azure OpenAI Service expands .NET SDK support

We're working on a migration guide from 1.0.0-beta* to 2.0.0-beta* and fully empathize with the hassle of needing to update code; we're confident that the new alignment with OpenAI and updated usability approaches will be substantial net positives, but that doesn't reduce the importance of minimizing how long and how frustrating it is to reach that net positive state.

Data_Juggler, the code you shared can be rewritten using 2.0.0-beta* as:

using Azure.AI.OpenAI;
using OpenAI.Chat;

AzureOpenAIClient azureClient = new();
ChatClient client = azureClient.GetChatClient(
    deploymentName: "gpt-35-turbo");

const string textFromUser = "Hello, assistant!"; // PromptTextBox.Text

ChatCompletion completion = client.CompleteChat(
    [
        new SystemChatMessage("You are an AI assistant.")
        {
            ParticipantName = "Steve",
        },
        new UserChatMessage(textFromUser),
    ]);

Console.WriteLine(completion.Content[0].Text);

You can find more samples and walkthroughs of the API on both OpenAI's GitHub repository and the Azure.AI.OpenAI project:

• azure-sdk-for-net/sdk/openai/Azure.AI.OpenAI at main · Azure/azure-sdk-for-net (github.com)

Hi,

Will you be providing a migration guide from 1.0.0-beta-17 to 2.0.0 since its obvious that a lot has changed?

Thanks,

Stu

I migrated from 1.0.0-beta-17 to 2.0.0 in just few hours on small proof of concept project. Very straight forward.

Thanks for the response. I am using Semantic Kernel and the upgrade does not go well with that. I opened an issue about it on the SK Github.

Cheers,

Stu

I upgraded to 2.0, and my code doesn't compile.

Why did they break existing functionality? ChatRequestMessage no longer exists.

ChatRequestMessage message1 = new ChatRequestAssistantMessage("You are an AI Assistant named Steve.");
message1.Role = ChatRole.Assistant;

// Get the user's question
ChatRequestMessage message2 = new ChatRequestUserMessage(PromptTextBox.Text);
message2.Role = ChatRole.User;

var chatCompletionsOptions = new ChatCompletionsOptions
{
DeploymentName = "DataJugglerGPT4o",
Messages = { message1, message2 }
};

I also had to change OpenAIClient to AzureOpenAIClient.

When existing code breaks due to an upgrade, that is bad if you want people to use the latest code. 

Is there a breaking changes document?

I'm Getting Compatibility issues when I tried to use this in my existing .NET framework project

I have upgraded code to 2.0. But it gave some errors. How to fix those errors?

OpenAIClient client = new OpenAIClient(new Uri(openAiEndpoint), new AzureKeyCredential(openAiApiKey));
var chatCompletionsOptions = new ChatCompletionsOptions
{
Messages =

{
new ChatMessage(ChatRole.System, @"You are the virtual assistance of ...."),

new ChatMessage(ChatRole.User, _conversationHistory)

},
Temperature = 0.5f,
MaxTokens = 150,
NucleusSamplingFactor = 0.95f,
FrequencyPenalty = 0,
PresencePenalty = 0,
};

var chatCompletionsResponse = await client.GetChatCompletionsAsync("gpt35turbo", chatCompletionsOptions);
string chatbotResponse = chatCompletionsResponse.Value.Choices[0].Message.Content;

I, too, am having trouble migrating from v1 to v2. Any word on when the migration document will be complete?

public class ChatService
{

private readonly IConfiguration _configuration;

private string SystemMessage = "You are an AI assistant that helps people find information about food. For anything other than food, respond with 'I can only answer questions about food.'";

public ChatService(IConfiguration configuration)
{
_configuration = configuration;
}
public async Task<Message> GetResponse(List<Message> messagechain)
{
string response = "";

AzureOpenAIClient client = new AzureOpenAIClient(
new Uri(_configuration.GetSection("Azure")["OpenAIUrl"]!),
new AzureKeyCredential(_configuration.GetSection("Azure")["OpenAIKey"]!));

ChatCompletionsOptions options = new ChatCompletionsOptions();
options.Temperature = (float)0.7;
options.MaxTokens = 800;
options.NucleusSamplingFactor = (float)0.95;
options.FrequencyPenalty = 0;
options.PresencePenalty = 0;
options.Messages.Add(new ChatMessage(ChatRole.System,SystemMessage));
foreach (var msg in messagechain)
{
if (msg.IsRequest)
{
options.Messages.Add(new ChatMessage(ChatRole.User, msg.Body));
}
else
{
options.Messages.Add(new ChatMessage(ChatRole.Assistant, msg.Body));
}
}

Response<ChatCompletions> resp = await client.GetChatCompletionsAsync(
_configuration.GetSection("Azure")["OpenAIDeploymentModel"]!,
options);

ChatCompletions completions = resp.Value;

response = completions.Choices[0].Message.Content;

Message responseMessage = new Message(response,false);
return responseMessage;
}
}
