"AddOpenAIService" seems not work in Blazor project

[LiveIsLive]

I created a (.NET 6)blazor project and added dependency injection in "Program.cs"：

builder.Services.AddOpenAIService(settings => settings.ApiKey = builder.Configuration["OpenAIServiceOptions:ApiKey"]);

Then I defined a OpenAIService object in "Index.razor"：

@inject OpenAI.GPT3.Managers.OpenAIService OpenAIService;

Fianally, I ran the project and get the error：

InvalidOperationException: Cannot provide a value for property 'OpenAIService' on type 'ColdShineSoft.BlazorChatGPTClient.Pages.Index'. There is no registered service of type 'OpenAI.GPT3.Managers.OpenAIService'.

Thanks in advance for any help!
