看看創(chuàng)建了什么

> ls ConsoleApp42/ConsoleApp42.csproj  Program.cs           obj/

dotnet new console --output ConsoleApp42 --name MyNewApp

using System;

namespace ConsoleApp42
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Hello World!");
}
}
}

為另一個(gè)項(xiàng)目做準(zhǔn)備

dotnet sln add ConsoleApp42/MyApp.sln

dotnet new nunitdotnet sln add Tests/MyAppTests.csproj

向項(xiàng)目添加新文件

說到模板，我們?cè)趺粗烙心男┛捎玫哪０迥兀?/span>如何區(qū)分項(xiàng)目模板（ project template）和項(xiàng)模板（item template）呢？這是 dotnet new --list 的工作，它可以輸出所有可用的模板列表：

自定義模板

> dotnet new classlib
Class library (C
Author: Microsoft
Description: A project for creating a class library that targets .NET Standard or .NET Core
Options:
-f|
netcoreapp2.1     - Target netcoreapp2.1
netstandard2.0    - Target netstandard2.0
Default: netstandard2.0


bool - Optional
Default: false / (*) true


* Indicates the value used if the switch is provided without a value.

添加自定義模板

創(chuàng)建自己的模板

namespace RootNamespace
{
public static class Main
{

}
}

cs
public class HomeController : Controller
{
public IActionResult Index() => View();

public IActionResult About()
{
ViewData["Message"] = "Your application description page.";
return View();
}

#if (EnableContactPage)
public IActionResult Contact()
{
ViewData["Message"] = "Your contact page.";
return View();
}
#endif

public IActionResult Error() => View();
}
