[BUG] Azure.AI.OpenAI beta.12: AzureExtensionsContext.Messages doesn't return citations since Jan. 12th, 2024 about azure-sdk-for-net

[LucGosso]

Reproduction Steps, Complete example with azure search endpoints

` AzureCognitiveSearchChatExtensionConfiguration extensionConfig = new()
{
SearchEndpoint = new Uri(_configuration["AzureSearchServiceEndpoint"] + ""),
Authentication = new OnYourDataApiKeyAuthenticationOptions(_configuration["AzureSearchServiceApiKey"]),
IndexName = _configuration["AzureSearchIndex"],
DocumentCount = 10,
//Key = _configuration["AzureSearchServiceApiKey"],
/FieldMappingOptions = new AzureCognitiveSearchIndexFieldMappingOptions()
{
ContentFieldNames = { "content" },
TitleFieldName = "metadata_storage_name",
UrlFieldName = "url",
FilepathFieldName = "metadata_storage_name"
}/
};
var chatCompletionsOptions = new ChatCompletionsOptions()
{
DeploymentName = _configuration["AzureOpenAiChatGptDeployment"],
Messages =
{
//new ChatRequestSystemMessage(promptTemplate),
new ChatRequestUserMessage(question),
},
// The addition of AzureChatExtensionsOptions enables the use of Azure OpenAI capabilities that add to
// the behavior of Chat Completions, here the "using your own data" feature to supplement the context
// with information from an Azure AI Search resource with documents that have been indexed.
AzureExtensionsOptions = new AzureChatExtensionsOptions()
{
Extensions = { extensionConfig }
}
};

Response response = await client.GetChatCompletionsAsync(chatCompletionsOptions);

ChatResponseMessage responseMessage = response.Value.Choices[0].Message;

if (responseMessage.AzureExtensionsContext.Messages?.Count > 0)
{
...
}
else
{
Console.WriteLine("No citations or other information.");
}
`

same issue here, as seen on debug screenshot

when using REST API in Postman against same resource, the response is fine, including citations

The issue was auto recovered just now. I can get citations again with the same .Net nuget.

Even though, the .Net version still needs to fix this as REST API or Python client were not impacted by the same issue at the same time even AOAI experienced some unknown behavior changes in past 24 hours.

We don't know when AOAI runs into the same situation and impacts .Net nuget again.

The same suggestion to #41138

Thanks.
