Re: [Netcommon-developer] Common.Logging: : Input string was not in a correct format

[Stephen B. <sb...@gm...>]

Hmm...I have to agree that sounds like a Common.Logging issue after all --
thanks for your help in trying to better isolate the problem.  Can you open
an issue here
https://github.com/net-commons/common-logging/issues?state=open and we'll
try to look into it for you soon --?

Thanks again,

-Steve B.
