Symptoms:

Getting this (The harvest type was not found in the list of loaded Heat extensions) error while trying to build a project in Visual Studio 2010.

MSBuild from cmdline builds it just fine.

Having this problem at least since 3.5

Investigation:

procmon showed that devenv.exe tries to open heat.exe.config from the ShadowCopy folder which looks like: C:\Users\UserName\AppData\Local\assembly\dl3\XG2847ZD.KP3\P7E7516P.3XC\c2e44358\5e5d6435_2dfecd01\heat.exe.config

The file is not there of course, so it doesn't load any extensions and eventually fails with the above error.

Solution:

string toolPath = Assembly.GetCallingAssembly().Location;

to

string toolPath = (new System.Uri(Assembly.GetCallingAssembly().CodeBase)).LocalPath;

Tested by copying the contents of the build folder to C:\Program Files (x86)\WiX Toolset v3.7\bin
and it seems to work fine now.

Similar Issue

I'm pretty sure this issue http://stackoverflow.com/questions/9290586/wix-darice-cub-file-missing-when-building-from-visual-studio-2010 is related to the above. It also happens only in Visual Studio. Probably \src\wix\Binder.cs(558) or \src\smoke\smoke.cs(168).
