We add an azure functions project in the solution, we want to make the repositories and services (WebCoreModule) successfully injected in our azure functions project. So, how can we achieve that?

Thanks.

    Hi @quTIP

    First of all, you need to create a Module in your new project (see https://aspnetboilerplate.com/Pages/Documents/Module-System). Then, you need to add a reference to EntityFrameworkCore module to your new project and also depend on your EFCore module in the new module you have created in your azure functions project.

    Thanks for the reply, I did as you mentioned and following is my module:

    using Abp.Modules; using Abp.Reflection.Extensions; using Bookenta.EntityFrameworkCore; namespace SalesVeeFunctionApp { [DependsOn( typeof(BookentaEntityFrameworkCoreModule) )] public class SalesVeeFunctionAppModule : AbpModule { public override void Initialize() { IocManager.RegisterAssemblyByConvention(typeof(SalesVeeFunctionAppModule).GetAssembly());

        }

    
}

    }

    When i try to inject my IRepository in my azure function constructor i got the following error

    Did i miss something? Thanks.

    Hi,

    Is it possible to share the full stack-trace as a text message ? You should be able to find it in Logs.txt file under App_Data folder.

    Sure,

    This is the full stack trace.

    Hi,

    Yes, this seems fine. Is Customer entity added to the DbContext ? If so, is it possible for us to access your project and check the source code ?

    Thanks for the replies,

    My issue is solved by doing the following:

    1- Updating My Module to be like this:

    public class SalesVeeFunctionAppModule : AbpModule
{
  
    public override void PreInitialize()
    {
        var configuration = GetConfiguration();

        Configuration.BackgroundJobs.IsJobExecutionEnabled = false;

        Configuration.UnitOfWork.Timeout = TimeSpan.FromMinutes(30);
        Configuration.UnitOfWork.IsTransactional = false;

        

        //Use database for language management
        Configuration.Modules.Zero().LanguageManagement.EnableDbLocalization();

        //**this line solve my issue**
        Configuration.Modules.AspNetZero().LicenseCode = configuration["AbpZeroLicenseCode"];
        Configuration.EntityHistory.IsEnabled = true;
        Configuration.EntityHistory.Selectors.Add("BookentaEntities", typeof(User), typeof(Tenant));

  
    }
    private static IConfigurationRoot GetConfiguration()
    {
        return AppConfigurations.Get(Directory.GetCurrentDirectory(), addUserSecrets: true);
    }
    public override void Initialize()
    { 
            IocManager.RegisterAssemblyByConvention(typeof(SalesVeeFunctionAppModule).GetAssembly());
       
    }

    
}

    2- Updating my program.cs to be like this:

    using Abp;
using Abp.AspNetCore;
using Abp.Dependency;
using Abp.Domain.Uow;
using Abp.PlugIns;
using Castle.Windsor.MsDependencyInjection;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using SalesVeeFunctionApp;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

var host = new HostBuilder().ConfigureFunctionsWorkerDefaults().ConfigureServices(services=> {


    services.AddAbp<SalesVeeFunctionAppModule>();
    var _bootstrapper = AbpBootstrapper.Create<SalesVeeFunctionAppModule>();
    services.AddSingleton(_bootstrapper);
    _bootstrapper.Initialize();
    



})
    .Build();
host.Run();

    So i can get my repositories in my azure function like this:

                var _bootstrapper = AbpBootstrapper.Create<SalesVeeFunctionAppModule>();
            using (var unit = _bootstrapper.IocManager.Resolve<IUnitOfWorkManager>().Begin())
            {
                var tester = _bootstrapper.IocManager.Resolve<IRepository<Customer>>();
                var d = tester.GetAllList();
            }

    Hi,

    I've been trying to get my Azure Function (project is running Abp 9.2.2) to work, but I'm encountering some issues.

    I followed the code example above, but I ran into a couple of problems. The _bootstrapper.IocManager.Resolve<>() method requires the arguments to be explicitly specified, as does the AbpBootstrapper.Create() method. For AbpBootstrapper.Create(), I assume you can use your own ProjectModule : AbpModule.

    When I implement the standard approach for creating Console application projects (similar to the Migrator project), I encounter dependency injection errors related to IServiceProvider or IUnitOfWorkManager.

    Is there an example Azure Functions project available, or could you provide guidance on how to resolve these issues?

    Thanks.

    Hi @Web2workNL,

    Could you share your Program.cs and your module class?

    After further debugging, I discovered that moving all the Initialize() into the function it allows it to start properly. The function project is runnig the In-process model. When using the Initialize() in my startup.cs, I get the following error: Cannot access a disposed object. Object name: 'IServiceProvider'.

    If using the Initialize() inside the function you can successfully execute a test method from my controller inside the Core project. However, when I run my method with a UnitOfWorkManager, I encounter the following error: System.Private.CoreLib: Exception while executing function: MyFunction. Castle.Windsor: Component Abp.Domain.Uow.UnitOfWorkDefaultOptions could not be registered. There is already a component with that name. Did you want to modify the existing component instead? If not, make sure you specify a unique name.

    My Function:

    public class MyFunction
{
    private readonly ILogger<MyFunction> _logger;

    public MyFunction(ILogger<MyFunction> logger)
    {
        _logger = logger;
    }

    [FunctionName(nameof(MyFunction))]
    public async Task Run([QueueTrigger("my-queue", Connection = "myConnString")] QueueMessage message)
    {
        using (var bootstrapper = AbpBootstrapper.Create<MyFunctionModule>())
        {
            // initialize here or in startup.cs - performance for starting function?
            bootstrapper.Initialize();

            using (var myCoreController = bootstrapper.IocManager.ResolveAsDisposable<IMyCoreController>())
            {
                // works fine
                var test = await myCoreController.Object.Test();
                _logger.LogInformation(test);

                // generates error:
                await myCoreController.Object.MyMethod();

            }
        }
    }
}

    Startup: (if used, it fails to start function)

    [assembly: FunctionsStartup(typeof(Startup))]

namespace MyFunctionsNameSpace
{
    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            using (var bootstrapper = AbpBootstrapper.Create<MyFunctionModule>())
            {
                bootstrapper.Initialize();
            }
        }
    }
}

    MyMethod - inside MyCoreController

    private async Task MyMethod()
{
    using (var uow = UnitOfWorkManager.Begin())
    {
        // code fails on first call the repository

        ...
        
        uow.Complete();
    }
}

    MyFunctionModule

    [DependsOn(typeof(MyProjectEntityFrameworkCoreModule))]
public class MyFunctionModule: AbpModule
{
    private readonly IConfigurationRoot _appConfiguration;

    public MyFunctionModule(MyProjectEntityFrameworkCoreModule abpZeroTemplateEntityFrameworkCoreModule)
    {
        abpZeroTemplateEntityFrameworkCoreModule.SkipDbSeed = true;

        _appConfiguration = AppConfigurations.Get(
            typeof(MyFunctionModule).GetAssembly().GetDirectoryPathOrNull()
        );
    }

    public override void PreInitialize()
    {
        Configuration.DefaultNameOrConnectionString = _appConfiguration.GetConnectionString("...");
        Configuration.Modules.AspNetZero().LicenseCode = _appConfiguration["..."];
    }

    public override void Initialize()
    {
        IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
        ServiceCollectionRegistrar.Register(IocManager);
    }
}

    Thank you for the response. I tried the solution. 2 issues:

    1. The IServiceCollection does not contain a definition for AddApplication on builder.Services.AddApplication<MyFunctionsModule>().
    2. The type or namespace IAbpApplicationWithExternalServiceProvider could not be found on serviceProvider.GetRequiredService<IAbpApplicationWithExternalServiceProvider>().Initialize(serviceProvider);.
