Description Brett van Swelm 2013-07-01 16:20:36 UTC
With "D:\Applications\Mono-2.11.4\bin" and "C:\Windows\Microsoft.NET\Framework\v4.0.30319" in the path on my Windows machine:

===== response_file.txt =====
/r:"C:/Program Files (x86)/Reference Assemblies/Microsoft/Framework/.NETCore/v4.5/mscorlib.dll"
/r:"C:/Program Files (x86)/Reference Assemblies/Microsoft/Framework/.NETCore/v4.5/System.Runtime.dll"
===== end =====

Unhandled Exception:

The ordering of assemblies appears to be important: if I swap the two assemblies in the response file around I don't see the error.
