  <p>
     Prerequisite: Visual Studio 2015 Update 3
  </p>

  <p>
     前提条件: Visual Studio 2015 Update 3
  </p>

</h2>



The minimum requirement for developing Angular applications with Visual Studio is Update 3.
Earlier versions do not follow the best practices for developing applications with TypeScript.
To view your version of Visual Studio 2015, go to `Help | About Visual Studio`.

使用Visual Studio开发Angular应用程序的最低要求是Update 3。
早期版本没有遵循使用TypeScript开发应用程序的最佳实践。
要查看你的Visual Studio 2015版本号，到`Help | About Visual Studio`。

If you don't have it, install **[Visual Studio 2015 Update 3](https://www.visualstudio.com/en-us/news/releasenotes/vs2015-update3-vs)**.
Or use `Tools | Extensions and Updates` to update to Update 3 directly from Visual Studio 2015.

如果还没有，安装**[Visual Studio 2015 Update 3](https://www.visualstudio.com/en-us/news/releasenotes/vs2015-update3-vs)**。或者使用`Tools | Extensions and Updates`来直接在Visual Studio 2015中更新到Update 3。



<h2 id='prereq3'>

  <p>
     Prerequisite: Configure External Web tools
  </p>

  <p>
     前提条件: 配置External Web tools
  </p>

</h2>



Configure Visual Studio to use the global external web tools instead of the tools that ship with Visual Studio:

配置Visual Studio来使用全局External Web Tools，而非Visual Studio默认的工具：

  * Open the **Options** dialog with `Tools` | `Options`.

    到`Tools` | `Options`打开**Options**对话框


  * In the tree on the left, select `Projects and Solutions` | `External Web Tools`.

    在左边树型项目中，选择`Projects and Solutions` | `External Web Tools`。


  * On the right, move the `$(PATH)` entry above the `$(DevEnvDir`) entries. This tells Visual Studio to
    use the external tools (such as npm) found in the global path before using its own version of the external tools.

  * 在右侧，将`$(PATH)`移动到 `$(DevEnvDir`)上面。这样，Visual Stuio就会在使用自带的外部工具时，优先使用全局路径中的外部工具（比如npm）。

    Click OK to close the dialog.


  * 点击OK关闭对话框。

    Restart Visual Studio for this change to take effect.


  * 重启Visual Studio，以让设置变化生效。

Visual Studio now looks first for external tools in the current workspace and 
if it doesn't find them, it looks in the global path. If Visual Studio doesn't 
find them in either location, it will use its own versions of the tools.

Visual Studio将优先在当前的工作区查找外部工具，如果没有找到，便查找全局路径，如果还没有找到，Visual Studio就使用自带的工具版本。



<h2 id='prereq4'>

  <p>
     Prerequisite: Install TypeScript 2.2 for Visual Studio 2015
  </p>

  <p>
     前提条件: 安装TypeScript 2.2 for Visual Studio 2015
  </p>

</h2>



While Visual Studio Update 3 ships with TypeScript support out of the box, it currently doesn’t ship with TypeScript 2.2, 
which you need to develop Angular applications.

Visual Studio Update 3自带TypeScript支持，但是它的TypeScript版本开发Angular应用需要的不是2.2。

To install TypeScript 2.2:

要安装TypeScript 2.2：

 * Download and install **[TypeScript 2.2 for Visual Studio 2015](https://www.microsoft.com/en-us/download/details.aspx?id=48593)**
 
   下载并安装 **[TypeScript 2.2 for Visual Studio 2015](https://www.microsoft.com/en-us/download/details.aspx?id=48593)**

 * OR install it with npm: `npm install -g typescript@2.2`.
 
   或通过npm安装：`npm install -g typescript@2.2`。

You can find out more about TypeScript 2.2 support in Visual studio **[here](https://blogs.msdn.microsoft.com/typescript/2017/02/22/announcing-typescript-2-2/)**.

你可以在**[这儿](https://blogs.msdn.microsoft.com/typescript/2017/02/22/announcing-typescript-2-2/)**查看更多Visual Studio中TypeScript 2.2的支持。

At this point, Visual Studio is ready. It’s a good idea to close Visual Studio and 
restart it to make sure everything is clean.

至此，Visual Studio准备好了。重新启动Visual Stuido，这样我们可以有一个崭新的开始。

  </p>

</h2>



Restore the packages required for an Angular application as follows:

按下面的步骤恢复Angular应用程序需要的包：

* Right-click on the `package.json` file in Solution Explorer and select `Restore Packages`.
  <br>This uses `npm` to install all of the packages defined in the `package.json` file. 
  It may take some time.

  在Solution Explorer中右键点击`package.json`，选择`Restore Packages`。
  <br>这样，Visual Studio会使用`npm`来安装在`package.json`中定义的所有包. 
  这可能需要花一点时间。

* If desired, open the Output window (`View` | `Output`) to watch the npm commands execute.

  如果愿意，打开Output窗口(`View` | `Output`)来监控npm命令的执行情况。

* Ignore the warnings.

  忽略所有警告。

* When the restore is finished, a message in the bottom message bar of Visual Studio 
  should say: `Installing packages complete`. Be patient. This could take a while.

  当恢复完成后，将会出现一条消息：`Installing packages complete`。耐心点，这相当耗时间。
  
* Click the `Refresh` icon in Solution Explorer.

  在Solution Explorer里，点击`Refresh`图标。

* **Do not** include the `node_modules` folder in the project. Let it be a hidden project folder.

  **不要**将`node_modules`目录添加到项目中，让它隐藏。

首先，确认`src/index.html`已被设置为开始页面。
  在Solution Explorer中，右键点击`index.html`，选择选项`Set As Start Page`。

### To run in VS with F5

Most Visual Studio developers like to press the F5 key and see the IIS server come up. 
To use the IIS server with the QuickStart app, you must make the following three changes. 

1. In `index.html`, change base href from `<base href="/">` to `<base href="/src/">`.
2. Also in `index.html`, change  the scripts to use `/node_modules` with a slash 
instead of `node_modules` without the slash. 
3. In `src/systemjs.config.js`, near the top of the file, 
change the npm `path` to `/node_modules/` with a slash.


<div class="alert is-important">



After these changes, `npm start` no longer works.
You must choose to configure _either_ for F5 with IIS _or_ for  `npm start` with the lite-server.


</div>



### For apps that use routing

If your app uses routing, you need to teach the server to always return 
`index.html` when the user asks for an HTML page
for reasons explained in the [Deployment](guide/deployment#fallback) guide.

Everything seems fine while you move about _within_ the app. 
But you'll see the problem right away if you refresh the browser
or paste a link to an app page (called a "deep link") into the browser address bar.

You'll most likely get a *404 - Page Not Found* response from the server
for any address other than `/` or `/index.html`.

You have to configure the server to return `index.html` for requests to these "unknown" pages.
The `lite-server` development server does out-of-the-box.
If you've switched over to F5 and IIS, you have to configure IIS to do it.
This section walks through the steps to adapt the QuickStart application.

#### Configure IIS rewrite rules

Visual Studio ships with IIS Express, which has the rewrite module baked in. 
However, if you're using regular IIS you'll have to install the rewrite 
module.  

Tell Visual Studio how to handle requests for route app pages by adding these 
rewrite rules near the bottom of the `web.config`:


<code-example format='.'>
  &lt;system.webServer&gt;
    &lt;rewrite&gt;
      &lt;rules&gt;
        &lt;rule name="Angular Routes" stopProcessing="true"&gt;
          &lt;match url=".*" /&gt;
          &lt;conditions logicalGrouping="MatchAll"&gt;
            &lt;add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /&gt;
            &lt;add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /&gt;
          &lt;/conditions&gt;
          &lt;action type="Rewrite" url="/src/" /&gt;
        &lt;/rule&gt;
      &lt;/rules&gt;
    &lt;/rewrite&gt;
  &lt;/system.webServer&gt;

</code-example>



<div class="l-sub-section">



The match url, `<match url=".*" />`, will rewrite every request. You'll have to adjust this if 
you want some requests to get through, such as web API requests. 

The URL in `<action type="Rewrite" url="/src/"/>` should 
match the base href in `index.html`.


</div>



Build and launch the app with debugger by clicking the **Run** button or by pressing `F5`.

点击**Run**按钮或者按`F5`键，用调试器构建和启动应用。


<div class="l-sub-section">



It's faster to run without the debugger by pressing `Ctrl-F5`.

按`Ctrl-F5`不带调试器的运行应用，速度会更快。
