windows系統下的第一個console程式

標籤：

視窗+r 鍵，輸入cmd，開啟一個命令列視窗

切換到你的目標目錄

輸入 dotnet new

dotnet會自動幫你建立3個檔案。

NuGet.Config檔案主要定義了NuGet擷取nupkg包時的伺服器位址，具體內容如下

<?xml version="1.0" encoding="utf-8"?><configuration>  <packageSources>    <!--To inherit the global NuGet package sources remove the <clear/> line below -->    <clear />    <add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" />    <add key="api.nuget.org" value="https://api.nuget.org/v3/index.json" />  </packageSources></configuration>

Program.cs包含了應用的進入點，只簡單的輸出了經典的“Hello world！”具體內容如下

using System;namespace ConsoleApplication{    public class Program    {        public static void Main(string[] args)        {            Console.WriteLine("Hello World!");        }    }}

project.json是項目的設定檔，配置了依賴的包、運行環境等資訊。

關鍵的依賴關係dependencies需要注意，跟dnx時有了很大區別

具體內容如下

{    "version": "1.0.0-*",    "compilationOptions": {        "emitEntryPoint": true    },    "dependencies": {        "NETStandard.Library": "1.0.0-rc2-23811"    },    "frameworks": {        "dnxcore50": { }    }}

然後使用命令 dotnet restore來還原依賴的包

結果出錯：

error: The HTTP request to ‘GET https://api.nuget.org/v3-flatcontainer/system.reflection/index.json‘ has timed out after

100000ms.

error: Failed to retrieve information from remote source ‘https://dotnetmyget.blob.core.windows.net/artifacts/dotnet-cor

e/nuget/v3/flatcontainer/system.reflection/index.json‘.

/system.reflection/index.json‘ has timed out after 100000ms.

搞不懂咋搞的，竟然linux下很正常，自家的windows搞不定。
