We are chasing an issue never seen before in many years of .net development:
MSBUILD : error MSB4166: Child node "5" exited prematurely. Shutting down.
Diagnostic information may be found in files in the temporary files
directory named MSBuild_*.failure.txt.
We have no idea what is going on. This build machine has been in service for months, and runs builds under a CI system.
The question is: What dir do I look in for the diag files? I searched the whole system for msbuild*.txt , and find nothing.
The bigger question is... why can't msbuild.exe be more specific in its output RE exactly where the diag file is. msbuild.exe runs as a different user under CI, and it should be explicit where it is putting things.
