我在Windows 8上的Visual Studio 2012中创建了一个Windows窗体应用程序,目标.NET框架是4.5,我想使用Windows SDK的Datagramsocket库,因此我在编译时将目标操作系统版本更改为8.

我收到以下错误:

"错误1类型'System.IDisposable'在未引用的程序集中定义.您必须添加对程序集'System.Runtime,Version = 4.0.0.0,Culture = neutral,PublicKeyToken = b03f5f7f11d50a3a'的引用."

当我尝试使用版本4.0.30506(不幸的是我们现在绑定到此版本的ASP.NEt Web API)的Microsoft.AspNet.WebApi.HelpPage nuget包时,我收到以下错误.我使用的是Windows 7和.NET 4.5.

Compilation Error

Compiler Error Message: CS0012: The type 'System.Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

Source Error:

@using (Html.BeginForm("Index", "Employees", FormMethod.Post, new { encType = "multipart/form-data", name = "EmployeeForm" }))

    </tr>
    @Html.EditorFor(model => model.Employees)

}

第32行:@ Html.EditorFor(model => model.Employees)给出以下错误

CS0012: The type 'System.Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

我在另一个没有出现此错误的项目中使用了这种类似的方法.
