我有一个使用google url shortener API的WPF(.NET 4)项目,我已经通过nugget安装了客户端库https://www.nuget.org/packages/Google.Apis.Urlshortener.v1/1.7.0.25-beta

该应用程序在Visual Studio中工作正常,但一旦发布就抛出异常无法加载文件或程序集System.Threading.Tasks,Version = 2.5.19.0这个以及所有其他程序集都存在于安装文件夹中,并且它随应用程序一起发布.我搜索了互联网,人们建议手动绑定app.config中的依赖库,它仍然不起作用,因为app.config中已经提到了我的所有依赖库,下面是我的app.config的样子

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>

我有mvc 4母版页,我想在页面顶部显示用户特定菜单我正在检索用户数据

@using Agenda_MVC.Engine
@{

    List<Format> ContactEvents = Agenda_MVC.Classes.Utility.GetContactEventFormats(User.Identity.Name);
}

但是当我遍历列表时它会抛出null异常,在设置断点时列表不为null它有项目.

@foreach (var ContactEvent in ContactEvents)
                {
                    <div class="@(ContactEvent.EventId == ViewContext.RouteData.Values["id"].ToString() ? "StaticMenuItemSelected" : "StaticMenuItem")">
                       @Html.ActionLink(ContactEvent.Name.Length > 15 ? ContactEvent.Name.Substring(0, 15) + "..." : ContactEvent.Name, "Agenda", "Portal", new { id = ContactEvent.EventId }, new { @title = ContactEvent.Name })
                    </div>    
                }

我不知道我做错了什么.

方法的代码如下,我正在从Web服务中检索它

public static List<Format> GetContactEventFormats(string ContactId)
{
    //List<Format> EventFormats = HttpContext.Current.Cache["EventFormats" + ContactId] as List<Format>;
    List<Format> EventFormats = HttpContext.Current.Session["EventFormats" + ContactId] as List<Format>;

    if (EventFormats == null)
    { …
