example does not work

[uranio-235]

I came here from

https://docs.microsoft.com/en-us/azure/azure-functions/functions-dotnet-dependency-injection

The related example does not work with the following error:

Method not found: 'Microsoft.Extensions.DependencyInjection.IServiceCollection 
Microsoft.Azure.Functions.Extensions.DependencyInjection.IFunctionsHostBuilder.get_Services()'.

The error looks like this

[10/3/2020 19:15:45] Building host: startup suppressed: 'False', configuration suppressed: 'False', startup operation id: 'a86e9ee9-9a4c-4960-9ad9-9cb89b1266f6'

This is my startup

using System;

using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

using WealFunction.Data;
using WealFunction.Models.Entities;

// Fix this error:

[assembly: FunctionsStartup(typeof(WealFunction.Startup))]

namespace WealFunction
{
    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            builder.Services.AddTransient<User>();
        }

    } // class
}

An this is the related funcion:

using System;

using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;
using WealFunction.Abstract;
using WealFunction.Data;
using WealFunction.Models;

namespace WealFunction.Functions
{
    public class AnnualInterestRate
    {
        private readonly IRepository<User> _userIdal;

        public AnnualInterestRate(IRepository<User> userIdal)
        {
            _userIdal = userIdal;
        }

        [FunctionName("AnnualInterestRate")]
        public void Run([TimerTrigger("0 30 11 * * *", RunOnStartup = true)]TimerInfo myTimer)
        {
            return;
        } // Run


    } // class

I following the same instructions and I got the error:

Could not load file or assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=5.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. O sistema não pode encontrar o arquivo especificado.
Value cannot be null. (Parameter 'provider')

Nothing can solve it.

Sorry for the delayed response, we must have missed this issue. Are you still seeing the same problem with all the latest packages?

If you're still seeing this issue:

I cloned the sample and it ran for me without issues: https://github.com/Azure/azure-functions-dotnet-extensions/tree/main/src/samples/DependencyInjection/Scopes

Can you share a minimal repro project for me to investigate? It's likely something is setup different to how the above sample does things.
