var client = await Connect.Cloud(weaviateUrl, weaviateApiKey);

var movies = await client.Collections.Create(new CollectionCreateParams{
  Name = "Movie",
  VectorConfig = Configure.Vector("default", v => v.Text2VecWeaviate()),
});

public class Movie {
  public string Title { get; set; }
  public string Genre { get; set; }
}

var movies = client.Collections.Use<Movie>("Movie");
await movies.Data.Insert(new Movie { Title = "Inception", Genre = "Sci-Fi" });

var response = await movies.Query.NearText("dream", limit: 5);
foreach (var movieObject in response.Objects) {
  Console.WriteLine(movieObject.Properties.Title);
}

var ragResponse = await questions.Generate.NearText(
  "biology",
  limit: 2,
  groupedTask: new GroupedTask("Write a tweet with emojis about these facts."),
  provider: new Providers.OpenAI() { }
);

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddWeaviate(builder.Configuration.GetSection("Weaviate"));
