I'm trying to sign a ClickOnce application using a method overload that was specifically added in VS 2013 Update 3. (per this suggestion)
The class he is using is described by MSDN here, and it says the class comes from Microsoft.Build.Tasks.Core.dll. Notice that the usual "Other Versions" dropdown is missing, because this is only in Visual Studio 2013.
Where is Microsoft.Build.Tasks.Core.dll?
Since it says MSBuild is now deployed separately from .NET Framework, I tried looking here but no luck: C:\Program Files (x86)\MSBuild\12.0
