有一种方法可以检查,但它并不直接。Visual Studio更新是通过一个ATOM源发布的,该源目前托管在此处:
http://go.microsoft.com/fwlink/?LinkID=251032
该URL可以在以下位置找到:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CommonExtensions\Platform\Shell\Microsoft.VisualStudio.ExtensionManager.Implementation.pkgdef
在[$RootKey$\ExtensionManager\Repositories{52943709-1abb-4abe-b413-41e8bb6d0462}]键下。
上述URL不应更改任何版本的Visual Studio,但这并不是保证。如果你检查http://go.microsoft.com/fwlink/?LinkID=290886的响应,你将获得以下响应:

请注意,此源中有两个条目,您所感兴趣的是标题以“Visual Studio 2012 Update”开头的那个。
如果此文件中指定的版本(此处为11.0.60610.01)大于您计算机上的版本:
(Get-Item "${env:ProgramFiles(x86)}\Microsoft Visual Studio 11.0\common7\ide\devenv.exe").VersionInfo.ProductVersion
然后您需要下载并安装链接/@Update节点中的URL:
<link rel="update" type="text" href="http://go.microsoft.com/fwlink/?LinkID=302339"/>
该网址应重定向到包含更新的MSI文件。
