Execute CreateCompletion() ,then exit unexpectedly

[GrowingHacker]

When this piece of code is executed, it is accidentally exited, there is no error message, and the try catch is useless:
completionResult = await openAIService.Completions.CreateCompletion(new CompletionCreateRequest()
{
Prompt = "Once upon a time",
Model = Models.ChatGpt3_5Turbo
});

I don't think CreateCompletion works with ChatGpt3_5Turbo Model. Please try to use a different model or chat endpoint.

The same goes for using DaVinci3，Should I try the new version?

[GrowingHacker]

Oh ! I get it! It's async in the trickster, the main method doesn't wait for it！

[GrowingHacker]

It's the async causing trouble,Don't let the main method close soon ,make it to do something just like :
Console.ReadLine() OR Console.ReadKey()
OR Task.WaitAll(Task.Delay(1000));
