@uranio-235 Thank you for your feedback! This is most likely an issue in your local environment. Could you specify which version of Functions runtime you have tried this with?

Here's couple of resources that might help:

1. A complete sample that I have tested: https://github.com/mike-urnun-msft/AzureFunkDI
2. An existing issue where others are discussing different solutions that worked for them: https://github.com/Azure/azure-functions-dotnet-extensions#29

Thanks for you answer. I'm using VisualStudio 2019, just created azure function time triggers and follow such steps.

@uranio-235 Could you share your code in Startup.cs as well as in WealFunction.cs files? For getting the exact runtime version, in your command line, you can type in func and it should show as below:

Sample in my repo is working fine on VS2019 with the azure-functions-core-tools and Functions runtime versions as shown in the screenshot above.

@uranio-235 Since this channel is for driving improvements towards MS Docs and we haven't determined any faulty steps in this documentation from our review, we will now proceed to close this thread. If there are further questions regarding this matter, please engage the existing issue where the Functions team and the rest of Functions community may weigh in on the particular issue that you're encountering.

I'm getting same error. Any resolve?

[uranio-235]

Sorry my late, connection problems, this is my Startup.cs

using System;
using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using WealFunction.Abstract;
using WealFunction.Data;
using WealFunction.Models.Entities;

// Fix this error:
// Method not found: 'Microsoft.Extensions.DependencyInjection.IServiceCollection
// Microsoft.Azure.Functions.Extensions.DependencyInjection.IFunctionsHostBuilder.get_Services()'.
[assembly: FunctionsStartup(typeof(WealFunction.Startup))]

namespace WealFunction
{
    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            builder.Services.AddDbContext<AppDbContext>();
            builder.Services.AddTransient(typeof(IRepository<>), typeof(EFRepository<>));
            builder.Services.AddTransient<User>();
        }

    } // class
