'WorkerOptions' does not contain a definition for 'AddApplicationInsights' in isolated Azure function program.cs file

Question

I'm getting this dependency error below and I'm not sure why? I manually added "Microsoft.Extensions.DependencyInjection" package to try and fix the dependency error and have it referenced in my .csproj file. and I have the using statement at the top of my program.cs file, but it still couldn't be found.

I've done a dotnet restore and restarted VS Code a couple of times.

Here is what I see.

Here is the program.cs and my .csproj

using System;
using System.Threading.Tasks;
using Infrastructure.Data;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Hosting;
using Microsoft.EntityFrameworkCore;
using Microsoft.Azure.Functions.Worker.Configuration;

var sqlConnectionString = Environment.GetEnvironmentVariable("ConnectionStrings:SqlServerConnection");
var host = new HostBuilder()
    // .ConfigureFunctionsWorkerDefaults()
    .ConfigureFunctionsWorkerDefaults(builder =>
    {
        builder
            .AddApplicationInsights()
            .AddApplicationInsightsLogger();
    })
    .ConfigureServices(s =>
    {
        s.AddDbContext<DataContext>(
            options => options.UseSqlServer(sqlConnectionString)
        );
    })
    .Build();

host.Run();

You need to install

Microsoft.Azure.Functions.Worker.ApplicationInsights 1.0.0-preview4 

AND

Microsoft.Azure.Functions.Worker.Extensions.ApplicationInsights 1.0.0-preview4

for isolated functions to work with app insight
