Major - P3 In order to debug the issue in CSHARP-2371, I needed to increase the verbosity of cake to Diagnostic. This should be the default since it will aid in debugging similar problems in the future, and does not have a significant impact on the verbosity of the build.
With the default verbosity, I would get this output:
Copying file DnsClient.xml to C:/data/mci/8d02bdce5437b7a9c099c62324f7e77f/mongo-csharp-driver/artifacts/bin/net45/DnsClient.xml Error: One or more errors occurred. Finished executing task: BuildNet45 Command failed: command [pid=3808] encountered problem: exit status 1 Task completed - FAILURE.
With Diagnostic verbosity, I get this output which is much clearer:
Copying file DnsClient.xml to C:/data/mci/a0269cd9eee1320187779753221391a5/mongo-csharp-driver/artifacts/bin/net45/DnsClient.xml

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
