小编Jam*_*317的帖子

我试图将一个接口注入我的HomeController,我收到此错误:

InvalidOperationException:尝试激活时无法解析类型"Microsoft.Extensions.Configuration.IConfiguration"的服务

我的Startup类如下:

public Startup(IApplicationEnvironment appEnv)
{
    var builder = new ConfigurationBuilder()
        .SetBasePath(appEnv.ApplicationBasePath)
        .AddEnvironmentVariables()
        .AddJsonFile("appsettings.json");
    Configuration = builder.Build();
}

public IConfigurationRoot Configuration { get; set; }

public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddApplicationInsightsTelemetry(Configuration);

    services.AddEntityFramework()
        .AddSqlServer()
        .AddDbContext<ApplicationDbContext>(options => options
            .UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"]));

    services.AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();

    services.AddMvc();
    services.AddSingleton(provider => Configuration);

    // Add application services.
    services.AddTransient<IEmailSender, AuthMessageSender>();
    services.AddTransient<ISmsSender, AuthMessageSender>();
}

public void Configure(
    IApplicationBuilder app, 
    IHostingEnvironment env, 
    ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    app.UseApplicationInsightsRequestTelemetry();

    if (env.IsDevelopment())
    {
        app.UseBrowserLink();
        app.UseDeveloperExceptionPage();
        app.UseDatabaseErrorPage();
    }
    else …

我正在尝试使用它不会过去的包管理器控制台Initializing PowerShell Host....

我试着直接打开PowerShell而且我得到了

我以前有这个,最终不得不将计算机恢复到之前的日期.我试过了,它什么都没改变.有没有人有任何想法？

更新 事件查看器下的信息说

Windows PowerShell已启动进程上的IPC侦听线程:22300在AppDomain中:DefaultAppDomain.

我正在尝试在服务器上部署asp.net核心应用程序.我已经完成了以下步骤.

首先,这是一个Windows Server 2012 r2环境,它是一个全新的虚拟机.

1. 构建VM
2. 更新所有ms更新
3. 添加iis角色
4. 保证asp.net 3.5和4.5安装在机器上
5. 确保安装http重定向和静态内容
6. 安装.net核心包
7. 从Visual Studio发布自包含的应用程序(项目名称Web)
8. 将其添加到服务器上的文件夹中.
9. 尝试从web.exe运行

我得到控制台应用程序打开说现在正在侦听:http:// localhost:5000 10.我从这台机器上的chrome 转到http:// localhost:5000并找不到404.

我在本地机器上执行步骤7 8 9和10,这是Windows 10我的应用程序.

可以说我有一个Listbox

<ListBox ItemsSource="{Binding MyList}"/>

我有一个属性:

private List<dynamic> _myList;

public List<dynamic> MyList
{
    get { return _myList; }
    set
    {
        if(value==null)return;
        _myList = value;
        OnPropertyChanged();
    }
}

好的,现在我们得到了我的问题:我有几个类,我将有列表,我希望能够在这个ListBox中显示它们.

类别:

public class A
{
    public string S { get; set; }
    public int I { get; set; }
}

public class B
{
    public int C { get; set; }
    public string Name { get; set; }
    public string F { get; set; }
}

public class C
{
    public int I …

我正在尝试打补丁/并发布对服务器的调用，但它永远不会到达服务器。我试过用邮递员做这件事，它在那里工作。所以我很确定它与我的代码有关。

基本上，我的帖子和补丁是一样的，所以我只会展示补丁。

protected patch(url: string, body: any): Observable<any> {
    let options = this.getRequestOptions(body);
    return this.http.patch(this.baseUrl+url,JSON.stringify(body),options);
}
private getRequestOptions(body:any):RequestOptions{
    let cpHeaders = new Headers({ 'Content-Type': 'application/json' });
    let options = new RequestOptions({ headers: cpHeaders });

    return options;
}

请注意，this.baseUrl = "http://localhost/blah/api/和 url 被传递为test;

我很感激这里的任何帮助。提前致谢

更新

   [HttpPut]
    public virtual IHttpActionResult Patch([FromBody]T entity)
    {
        return Ok(_repository.Patch(entity));
    }

    [HttpPatch]
    public virtual IHttpActionResult WebPatch([FromBody]T entity)
    {
        return this.Patch(entity);
    }

我有一个代理配置，如下面的评论所示。

  "/api": {
    "target": "http://localhost/QuickQuoteApi",
    "secure": false,
    "pathRewrite": {
      "^/api": "" …

我有一个我正在构建的ASP.NET MVC应用程序,我无法弄清楚为什么被回发的模型总是为空.

CSHTML:

<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
    @Html.HiddenFor(model => model.TotalItemCategoryId, new { htmlAttributes = new { @class = "form-control" } })
