c# - ASP.NET 5 控制台应用程序 dnxcore50 缺少 `System.Net.Http' 程序集引用？

Question

我在 OS X 上使用 visual studio code 并尝试使用 System.Net.Http 和 dnxcore50 发出 HTTP 请求。当我运行 mcs -debug Program.cs 时，我收到消息:

Program.cs(2,18): error CS0234: The type or namespace name 'Http' does not exist in the namespace 'System.Net'. Are you missing 'System.Net.Http' assembly reference?`

这是我的 project.json:

{
"version": "1.0.0-*",
"description": "Console Application",
"authors": [
    "your name"
],
"tags": [
    ""
],
"projectUrl": "",
"licenseUrl": "",
"dependencies": {
    "Newtonsoft.Json": "7.0.1",
    "System.Net.Http": "4.0.1-beta-23217",
    "Microsoft.AspNet.WebApi.Client": "5.2.3"
},
"commands": {
    "ConsoleApplication": "ConsoleApplication"
},
"frameworks": {
    "dnx451": {},
    "dnxcore50": {
        "dependencies": {
            "Microsoft.CSharp": "4.0.1-beta-23217",
            "System.Collections": "4.0.11-beta-23217",
            "System.Console": "4.0.0-beta-23217",
            "System.Linq": "4.0.1-beta-23217",
            "System.Threading": "4.0.11-beta-23217"
        }
    }
}

如果您使用 DNX，则不会直接调用 C# 编译器。 Mcs 不知道如何编译新项目。你应该使用 dnu build相反:

dnu build <path to your project.json>
