How can I check for Visual Studio updates via the command line? - visual-studio-2012

Question

In an attempt to streamline my Virtual Environment setup, I'm using Chocolatey to automate my VM.
Since I can run the cinst command to install Visual Studio
c:\> cinst VisualStudio2012Professional
I'm wondering if after it's installed, is there a command line switch to check for (and subsequently "install") updates within Visual Studio?
Something along the lines of...
"C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe" /InstallUpdates
This should also extend to any extensions that are installed along side VS.

Answer 1

There is a way to check but it is not at all straight forward. Visual Studio Updates are published via an ATOM feed that is currently hosted here:
http://go.microsoft.com/fwlink/?LinkID=251032
This URL can be located in:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\CommonExtensions\Platform\Shell\Microsoft.VisualStudio.ExtensionManager.Implementation.pkgdef
Under the [$RootKey$\ExtensionManager\Repositories{52943709-1abb-4abe-b413-41e8bb6d0462}] key.
The above URL should not change for any version of Visual studio BUT that is not a guarantee. If you examine the response of http://go.microsoft.com/fwlink/?LinkID=290886, you will currently get this response:

Note that there are two entries in this feed and the one you are interested in is the one with a title beginning with "Visual Studio 2012 Update."
If the Version specified in this file (11.0.60610.01 here) is greater than the version you have on disk:
(Get-Item "${env:ProgramFiles(x86)}\Microsoft Visual Studio 11.0\common7\ide\devenv.exe").VersionInfo.ProductVersion
Then you would want to download and install the url in the Link/#Update node:
<link rel="update" type="text" href="http://go.microsoft.com/fwlink/?LinkID=302339"/>
That Url should redirect to an MSI that has the update.

Answer 2

Based on the information located in the Devenv Command Line Switches MSDN documentation. There is currently no way to call a command line swtich in order to check for / install updates to Visual Studio.
however Matt Wrock shows a nice workaround in his answer.

Answer 3

The answer from #Matt is outdated. For VS2019 follow this way:
Download file at https://aka.ms/vs/16/release/channel (it will be plain JSON file 'VisualStudio.16.Release.chman')
Check node: info->productDisplayVersion (or buildVersion) - they give enough info.
