After reading this post from Sayed (a great blogger by the way!) I downloaded and installed the VS2010 Web Publish Updates. All was well until I realised that all my WiX projects were now showing as unavailable in solution explorer. The system is failing looking for a .wpp.targets file which does not exist. I've tried all sorts of things including:

  • creating the file it wants (it still thinks it doesn't exist)
  • overriding the publish profile properties in the wixproj file (no change)
  • using alternative targets (no change)

After 4hrs of digging around in the 10.5 targets files I'm drawing a blank on all fronts. I'll keep working on it but in the meantime I'd recommend staying off the upgrade.

If you're a brave soul and want to help me fix this, I'm keeping a question on StackOverflow updated with my attempts, get involved!
