You have an Azure subscription that contains an Azure OpenA1 resource named All.

You are using the Azure OpenAI .NET SDK to send a prompt (“What is Microsoft Azure?”) to a text model deployment. For text generation, you must call the Completions endpoint; hence client.GetCompletions(...) (or the async variant) is correct.

The Response object returns one or more choices; the generated text is contained in response.Value.Choices[0].Text, which you can write to the console.

GetEmbeddings would return vector embeddings, not natural-language text, and GetImageGenerations is for DALL·E image generation, so neither meets the requirement to “answer user questions” and print text.
