Question

我目前正在创建Azure Fucntion。 DI Layer是一个.net标准项目。我使用autofac作为我的DI库。所有内容都会编译，但在运行时它会为我提供方法未找到异常。我读了很多文章说我需要升级我的所有nuget包。这对我有点帮助。这是失败的代码

（。netstandard）DI项目 - ＆gt; InjectConfuguration.cs

using Autofac;
using Autofac.Extensions.DependencyInjection;
using Awesomeness.AutofacInjection;
using Microsoft.Azure.WebJobs.Host.Bindings;
using Microsoft.Azure.WebJobs.Host.Protocols;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Threading.Tasks;

......这里有些代码..

var services = new ServiceCollection();
    ... some code here ...
    var containerBuilder = new ContainerBuilder();

                containerBuilder.RegisterModule(new ApplicationModule());
                containerBuilder.Populate(services); // Exception here

                var applicationContainer = containerBuilder.Build();

               var serviceProvider = new AutofacServiceProvider(applicationContainer);

                return serviceProvider;

例外：

  Method not found: 'Void 
Autofac.Extensions.DependencyInjection.AutofacRegistration.Populate(Autofac.ContainerBuilder, 
System.Collections.Generic.IEnumerable`1<Microsoft.Extensions.DependencyInjection.ServiceDescriptor>)'.

栈跟踪

at ProjectName.Functions.DI.DIConfig.<>c.<.ctor>b__0_0(ContainerBuilder builder)
   at AzureFunctions.Autofac.Configuration.DependencyInjection.Initialize(Action`1 cfg)
   at ProjectName.Functions.DI.DIConfig..ctor()

（.net framework）功能项目 - ＆gt; Function1.cs

using System;
using Awesomeness;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;

namespace FunctionApp2
{
    public static class Function1
    {
        [FunctionName("Function1")]
        public static void Run([TimerTrigger("0 */1 * * * *", RunOnStartup = true)]TimerInfo myTimer, TraceWriter log, [Inject] IAwesomeClass awesomclass)
        {

            log.Info($"C# Timer trigger function executed at: {DateTime.Now}");
            log.Info($"{awesomclass.VeryAwesomeMethod()} at: {DateTime.Now}");
        }
    }
}

我创建了一个复制我的错误的虚拟项目。 https://www.mediafire.com/file/j03x3v6c55gy1aq/Awesomeness.zip

Answer 1

将 Microsoft.Extensions.DependencyInjection 降级到 ver. 3.1.4 对我来说是有效的。
