Aspire integration with AWS Lambda project provided by AWS Toolkit for Visual Studio

Hi There,

I have been using AWS Lambda Project with ASP.NET Web API and deploying the same in AWS Lambda but now I want to integrate the .NET Aspire which is a cloud ready stack and gives many advantages like Observability support, etc..

in the AWS Lambda Project type we have two classes namely LambdaEntryPoint.cs and LocalEntryPoint.cs and I have done the changes in LocalEntryPoint.cs and running the project locally Aspire Dashboard is also coming but I want to deploy the same AWS Lambda and for this we need to change in LambdaEntryPoint.cs file and I am facing the issue for the same.

In the LambdaEntryPoint.cs I can see below two methods

/// <summary>
/// The builder has configuration, logging and Amazon API Gateway already configured. The startup class
/// needs to be configured in this method using the UseStartup<>() method.
/// </summary>
/// <param name="builder"></param>
protected override void Init(IWebHostBuilder builder)
{
    builder
        .UseStartup<Startup>();
}

/// <summary>
/// Use this override to customize the services registered with the IHostBuilder. 
/// 
/// It is recommended not to call ConfigureWebHostDefaults to configure the IWebHostBuilder inside this method.
/// Instead customize the IWebHostBuilder in the Init(IWebHostBuilder) overload.
/// </summary>
/// <param name="builder"></param>
protected override void Init(IHostBuilder builder)
{
}

But the Aspire needs WebApplicationBuilder which inherits from IHostApplicationBuilder so how can I call the methods like below AddServiceDefaults methods which is extension method of type IHostApplicationBuilder

public static IHostApplicationBuilder AddServiceDefaults(this IHostApplicationBuilder builder)
{
    builder.ConfigureOpenTelemetry();

    builder.AddDefaultHealthChecks();

    builder.Services.AddServiceDiscovery();

    builder.Services.ConfigureHttpClientDefaults(http =>
    {
        // Turn on resilience by default
        http.AddStandardResilienceHandler();

        // Turn on service discovery by default
        http.AddServiceDiscovery();
    });

    return builder;
}
