- 新增`Rougamo.Extensions.DependencyInjection.Autofac.AspNetCore`，`Rougamo.Extensions.DependencyInjection.Autofac`

## Rougamo.Extensions.DependencyInjection.Autofac.AspNetCore

### 快速开始

```csharp
// 注册Rougamo（注：如果你不使用IoC/DI功能，Rougamo默认是不需要注册操作的）
public static void Main(string[] args)
{
   var builder = WebApplication.CreateBuilder(args);
   builder.Host
           .UseServiceProviderFactory(new AutofacServiceProviderFactory())
           .ConfigureContainer<ContainerBuilder>(builder =>
           {
               builder.RegisterRougamoAspNetCore();
           });
   
   // 注册IHttpContextAccessor也是必须的
   builder.Services.AddHttpContextAccessor();
}

// 在切面类型中获取ILifetimeScope实例并使用
public class TestAttribute : MoAttribute
{
   public override void OnEntry(MethodContext context)
   {
       // 使用扩展方法GetAutofacCurrentScope获取ILifetimeScope实例
       var scope = context.GetAutofacCurrentScope();

       // 使用ILifetimeScope
       var xxx = scope.Resolve<IXxx>();
   }
}
```

### 非HttpContext Scope

默认情况下通过`MethodContext`的扩展方法`GetAutofacCurrentScope`只会尝试获取当前`HttpContext`对应的`ILifetimeScope`，如果当前没有`HttpContext`，那么就会返回根`IServiceProvider`。这样的设计是因为一般而言我们不会在AspNetCore的项目中手动创建一个scope，如果你确实有手动创建scope的场景需求，请按如下的方式操作：

```csharp
public static void Main(string[] args)
{
   var builder = WebApplication.CreateBuilder(args);
   builder.Host
           .UseServiceProviderFactory(new AutofacServiceProviderFactory())
           .ConfigureContainer<ContainerBuilder>(builder =>
           {
               builder.RegisterAutofacNestableHttpContextScopeAccessor(); // 额外的注册步骤
               builder.RegisterRougamoAspNetCore();
           });
   
   // 注册IHttpContextAccessor也是必须的
   builder.Services.AddHttpContextAccessor();
}

public class Cls(IServiceProvider services)
{
   public void M()
   {
       // 调用扩展方法BeginResolvableLifetimeScope创建scope，这里如果使用BeginLifetimeScope来创建，那么这个scope将无法在切面类型中获取到
       using var scope = services.BeginResolvableLifetimeScope();
   }
}
```

## Rougamo.Extensions.DependencyInjection.Autofac

```csharp
// 注册Rougamo（注：如果你不使用IoC/DI功能，Rougamo默认是不需要注册操作的）
public static void Main(string[] args)
{
   var builder = Host.CreateDefaultBuilder();
   
   builder
       .UseServiceProviderFactory(new AutofacServiceProviderFactory())
       .ConfigureContainer<ContainerBuilder>(builder =>
       {
           builder.RegisterRougamo();
       });
}

// 在切面类型中获取IServiceProvider实例并使用
public class TestAttribute : MoAttribute
{
   public override void OnEntry(MethodContext context)
   {
       // 使用扩展方法GetAutofacCurrentScope获取ILifetimeScope实例
       var scope = context.GetAutofacCurrentScope();

       // 使用ILifetimeScope
       var xxx = scope.Resolve<IXxx>();
   }
}
```
