找不到方法app.UseStaticFiles()

问题描述

我正在关注本指南在第4步中，系统要求我在 project.json 文件中添加三行(我这样做了，然后运行 dotnet restore 得到很多更新的软件包).

I'm following this guide and in step 4, I'm asked to add three lines to the project.json file (which I did and then ran dotnet restore getting a lot of updated packages).

当我在 Configure 方法中输入三行时，所有行上都出现红线.无法识别该方法，未提供智能感知等.

When I enter the three lines in the Configure method, I get red lines on all of them. The methods aren't recognized, no intellisense provided etc.

我还注意到，在本指南的示例中，方法签名仅采用 IApplicationBuilder 的一个参数，而生成的参数是使用( yo aspnet 命令生成的) )看起来像这样.

I also noticed that in the example in the guide, the method signature only takes one parameter of IApplicationBuilder, whereas the one I got generated (using the yo aspnet command) looks like this.

Configure(IApplicationBuilder, IHostingEnvironment, ILoggerFactory);

我不确定该如何解决.我的猜测是，此过程中有一个新版本的东西(Yo，Generators，Core等)，但我不确定.

I'm not sure how to resolve it. My guess is that there's a new version of something in the process (Yo, Generators, Core etc.) but I'm not entirely sure.

我还找到了此博客方法签名与我得到的签名相似.但是，它的作者提出了对我不起作用的相同语法.我猜这是引用错误的库的问题.我该如何解决这个问题?

I've also found this blog where the method signature resembles the one I'm getting. However, the author of it suggest the same syntax that doesn't work for me. I'm guessing it's a matter of referencing the wrong libraries. How do I approach the issue?

推荐答案

从链接的教程中的屏幕截图来看，它与ASP.NET Core RC1有关(当时称为ASP.NET 5 r1-final).您可以在包和名称空间名称上轻松识别这一点. Microsoft.AspNet.*一直使用到rc1.

Judging from the screenshots in the linked tutorial, its about ASP.NET Core RC1 (back then called ASP.NET 5 r1-final). You can easily recognize this on the package and namespace names. Microsoft.AspNet.* is used until rc1.

从RC2开始，这些软件包已重命名为Microsoft.AspNetCore.*，以使其更清楚其新框架，并且与旧版ASP.NET的兼容性不高.

Starting with RC2 the packages were renamed to Microsoft.AspNetCore.* to make it clearer its a new framework and not that much compatible with legacy ASP.NET.

UseIISPlatformHandler()不再存在，它现在在Main(...)方法中的UseIISIntegration()中:

The UseIISPlatformHandler() isn't there anymore, it's now UseIISIntegration() within the Main(...) method:

public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .Build();

        host.Run();
    }
}

包，包是Microsoft.AspNetCore.Server.IISIntegration": "1.0.0"和"Microsoft.AspNetCore.Server.Kestrel": "1.0.1".对于静态文件，它是:"Microsoft.AspNetCore.StaticFiles": "1.0.0".

And the packages the package is Microsoft.AspNetCore.Server.IISIntegration": "1.0.0" and "Microsoft.AspNetCore.Server.Kestrel": "1.0.1". For static files it's: "Microsoft.AspNetCore.StaticFiles": "1.0.0".

对于Configure重载:Configure(IApplicationBuilder);是默认值，但是您可以添加在依赖项注入系统中注册的任何其他类型(在ConfigureServices方法中)，因为它是一个约定俗成的系统(startup.cs ).

For the Configure overload: Configure(IApplicationBuilder); is default one, but you can add any other type which is registered with the dependency injection system (in ConfigureServices method), as it's a convention system (the startup.cs).
