问题
After installing Update 4, I now find myself unable to build (or even clean) any solution. I keep getting:
Error 1 The "CheckPathAttributes" task could not be loaded from the assembly C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.Publishing.Tasks.dll. Could not load file or assembly 'file:///C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web\Microsoft.Web.Publishing.Tasks.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. HandlePageNotFound
Does anyone know how to resolve this please?

Well, here's "my solution".
First the horrific "prompt of death" (plus the same "licensing issue" annoyance) in this post:
What I've attempted (and result) based on info from the interwebs:
Close VS 2013 and rename the folder:
C:\Users\[your user name]\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache
Result: No effect/errors persist (VS will re-create that folder on startup)Rerun the Visual Studio Update 4 installer and
Repair
Result: Successfully "fixed" whatever it was.
This will take about an hour which is slower than when I originally installed the update so that was a clue, or rather, more like "well, I hope that means it found what it did wrong or forgot/missed out on" (and not, "oh crap, now I'm really screwing things up even more")
A quick summary of my environment so that hopefully will guide you to your solution:
I did install
Office Developer Tools Nov 2014prior to the Update so in my case, that wasn't the issue (I did not remove/uninstall)I have
Resharper, and I did not disable it, so this too doesn't seem related (some have pointed this out)I did update to
Web Essentials 2013 for Update 4after the initial Update (it will prompt you to after installing VS Update 4). I didn't do anything after theRepair(didn't remove/re-install/etc Web Essentials after theRepair).I have VS 2012 as well, just mentioning this though that was never affected in any way (and was my fallback while this issue was stopping me from using VS2013)
Hth...

Found the solution via this
TransformXml task could not be loaded from Microsoft.Web.Publishing.Tasks.dll
In my case, I had Visual Studio 2012 installed on an E: drive already, so I found a copy of Microsoft.Web.Publishing.Tasks in
E:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\Web
So I copied that file, and Microsoft.Web.XmlTransform to here:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web
and now all is well :)

Uninstalling "Office Developer Tools for Visual Studio 2013 – November 2014 Update" helped me. Now all works as before.
回答4:
If you have VS 2012 installed on your machine. Copy Microsoft.Web.Publishing.Tasks.dll and Microsoft.Web.Publishing.targets from C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\web\ into C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web (the path for VS 2013). Restart visual studio.

I have only VS2013 (now with Update 4) and I solve this problem as follows: Close VS, copy "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.Tasks.Dll" into the "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web" directory and start VS (folder v11.0 no contains Web subfolder). Now I can rebuild website projects without any error again.
回答6:
My problem cleared thanks to the same TransformXml link and the suggestion to install Windows SDK for Windows 7 and .NET Framework 4
回答7:
Copying "Microsoft.Web.Publishing.Tasks.dll" and "Microsoft.Web.XmlTransform.dll" from "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\Web" to "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\Web" also works
