I have recently installed the new Azure development tools for Visual Studio 2010 service pack 1. Every time that I try to publish an existing website (using file system depl
I've been struggling with the same problem with Visual Studio 2013 (and 2015).
The crucial fix for me was to add the VSToolsPath property setting, which was missing in my project file, for whatever reason.
I added this into the directive:
$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)
As a side note: My project file is also referencing the v10.0 version of the Microsoft.WebApplication.targets file, but that seems to be okay.
