我想将Autofac添加到.Net Core应用程序中。
我已尝试执行Autofac:Getting started tutorial的所有步骤,我已安装Autofac.Extensions.DependencyInjection
,已更新Program
课程,但无法添加autofac,例如。
获取错误
错误CS1061' IServiceCollection'不包含的定义 ' AddAutofac'没有扩展方法' AddAutofac'接受第一个 类型的参数' IServiceCollection'可以找到(你错过了吗? using指令或程序集引用?)
重新安装nuget包,清洁&重建解决方案,关闭VS - 没有帮助的事情。
public class Program
{
public static void Main(string[] args)
{
var host = new WebHostBuilder()
.UseKestrel()
.ConfigureServices(services => services.AddAutofac()) //here is problem
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
}
Autofac版本 - 4.6.2 Autofac.Extensions.DependencyInjection版本 - 4.2.0

尝试添加using Autofac.Extensions.DependencyInjection;
using System.IO;
using Autofac.Extensions.DependencyInjection;
using Microsoft.AspNetCore.Hosting;
namespace App
{
public class Program
{
public static void Main(string[] args)
{
var host = new WebHostBuilder()
.UseKestrel()
.ConfigureServices(services => services.AddAutofac())
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.Build();
host.Run();
}
}
}
