VS2015 ASP.NET 5空项目无法正常工作，找不到ConfigurationBuilder.Build [英] VS2015 ASP.NET 5 Empty project doesn't work, can't find ConfigurationBuilder.Build
问题描述
尝试新的VS2015项目.我正在关注本教程，但是缺少它某物.当我运行它时，出现500错误:
Trying out the new VS2015 projects. I was following this tutorial but it's missing something. When I run it I get a 500 error:
System.MissingMethodException: Method not found: 'Microsoft.Framework.Configuration.IConfiguration Microsoft.Framework.Configuration.ConfigurationBuilder.Build()'.
at Microsoft.AspNet.Loader.IIS.RuntimeHttpApplication.ApplicationStart(IHttpApplication application)
at Microsoft.AspNet.Loader.IIS.HttpApplicationBase.InvokeApplicationStart(IHttpApplication application)
.NET Framework version 4.0.30319.42000 | Microsoft.AspNet.Loader.IIS version 1.0.0-beta5-11951 | IIS version 10.0.10117.0 (fbl_srv2_iis_dev(sujitn).150512-1839) | Need help?
经过一番阅读，我发现您需要一个Configuration实例，尽管我发现的示例对我不起作用.他们都将实例设置为配置"字段，但是似乎不存在.这些配置行全为红色，因为名称不存在:
After some reading I discovered that you need a Configuration instance, though the examples I found don't work for me. They all set the instance to a Configuration field but that doesn't seem to exist. These Configuration lines are all red because the name doesn't exist:
public class Startup
{
public Startup() {
Configuration = new ConfigurationBuilder();
}
public void ConfigureServices(IServiceCollection services)
{
Configuration = new ConfigurationBuilder();
services.AddMvc();
}
public void Configure(IApplicationBuilder app)
{
Configuration = new ConfigurationBuilder();
app.Run(async (context) =>
{
await context.Response.WriteAsync("Hello World!");
});
app.UseMvc(m => {
m.MapRoute(
name: "default",
template: "{controller}/{action}/{id?}",
defaults: new { controller = "Home", action = "Index" });
});
}
}
这是使用空项目中的默认Startup类.我手动添加了gulp和angular节点模块.我一定想念一些东西，但我不知道是什么...
This is using the default Startup class from the empty project. I added the gulp and angular Node modules manually. I must be missing something but I have no idea what...
更新:这些是我在Startup.cs中的用法:
Update: These are my usings in Startup.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNet.Builder;
using Microsoft.AspNet.Http;
using Microsoft.Framework.DependencyInjection;
using Microsoft.Framework.Configuration;
更新:这是我当前的 project.json 文件(我尚未手动修改):
Update: This is my current project.json file (I haven't modified this manually yet):
{
"webroot": "public",
"version": "1.0.0-*",
"dependencies": {
"Microsoft.AspNet.Mvc": "6.0.0-beta7",
"Microsoft.AspNet.Server.IIS": "1.0.0-beta5",
"Microsoft.AspNet.Server.WebListener": "1.0.0-beta5"
},
"commands": {
"web": "Microsoft.AspNet.Hosting --config hosting.ini"
},
"frameworks": {
"dnx451": { },
"dnxcore50": { }
},
"publishExclude": [
"node_modules",
"bower_components",
"**.xproj",
"**.user",
"**.vspscc"
],
"exclude": [
"public",
"node_modules",
"bower_components"
]
}
更新:根据注释将 beta5 s更改为 beta7 s后，我跳过了此 ConfigurationBuilder 错误，然后转到无法加载文件或程序集'Microsoft.Dnx.Host.Clr'或其依赖项之一"错误，我怀疑这是另一个版本问题，我现在正在调查...但是我想应该是一个不同的问题.
Update: After changing the beta5s to beta7s, based on comments, I got past this ConfigurationBuilder error and moved on to a "Could not load file or assembly 'Microsoft.Dnx.Host.Clr' or one of its dependencies" error, which I suspect is another version issue and I'm looking into now...but that would be a different question I suppose.
推荐答案
如Henk Mollema的评论中所述，未找到 ConfigurationBuilder.Build 的原因，而我的 Configuration 行是红色的是我混合了软件包版本(有些beta5和一些beta7).此功能或者是在beta5之后的版本中添加的，或者由于库不匹配而找不到.在 project.json 中升级到beta7可以解决该问题.
As noted in comments by Henk Mollema, the reason ConfigurationBuilder.Build was not found and my Configuration lines were red is that I had mixed package versions (some beta5 and some beta7). This functionality was either added in a version later than beta5, or it couldn't be found due to the mismatched libraries. Upgrading to beta7 in project.json fixed it.
我提到的后续错误也是也已修复.
The subsequent error I mentioned was fixed as well.
