Having a very strange issue with our .NET 3.5 builds after the upgrade from 8.0.x to 8.1.1, it seems to “force” loading 64-bit DLL’s even though all project files and build steps are set to “x86″ for the platform choice. It also seems to have set every build configuration to use .NET Framework 4.0.
All my builds are failing, I am enabling debug logging on one of the agents and register an issue on the community forums :-\
