.Net: `GetTextContentAsync` extension method expects single output from `textGenerationService.GetTextContentsAsync`.

[mku-wedoai]

Describe the bug
GetTextContentAsync extension method expects single output from textGenerationService.GetTextContentsAsync.

See

semantic-kernel/dotnet/src/SemanticKernel.Abstractions/AI/TextGeneration/TextGenerationExtensions.cs

Line 34 in 246b843

.Single();

I think that the Single() is not necessary here. Also, Python version of SK allows returning multiple instances of TextContent from get_text_contents method.

Platform

• OS: Windows 11
• IDE: Visual Studio 17.10.0
• Language: C#
• Source: NuGet package version 1.13.0

The same would apply for the GetChatMessageContentAsync in the ChatCompletionServiceExtensions:

semantic-kernel/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/ChatCompletionServiceExtensions.cs

Line 57 in 02145d9

public static async Task<ChatMessageContent> GetChatMessageContentAsync(

Also the return type description does not fit the actual return type:

semantic-kernel/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/ChatCompletionServiceExtensions.cs

Line 56 in 246b843

/// <returns>List of different chat results generated by the remote model</returns>

@markwallace-microsoft I would like to kindly ask if there is any possibility of prioritising this issue?

Hi @mku-wedoai , here is PR: #6590

Hey @dmytrostruk, thank you for the contribution!

I have a question - after your change extension methods still return one element. I think that the solution would be to return all generated elements. ITextGenerationService allows to return multiple instances of TextContent from GetTextContentsAsync, so why somewhere in the SK code these results are cut to a single element?

@mku-wedoai I think I misunderstood your issue in the first place. You are talking about returning multiple values from kernel.InvokeAsync, is that correct?

[mku-wedoai]

@dmytrostruk No worries :) Yes, in the big picture I'd like kernel.InvokeAsync to return multiple values.
