I have a bunch of web services that hook into NPM via .NET using the SolarWinds.InformationService.Contract2.dll -- Been working great to display information to users that do not have direct access to NPM for information sharing; however, we upgraded to NPM 10.5 this afternoon and the InfoProxyService.Read(nodeuri) method throws an Exception I'm not sure what to make of. I made no changes to my .NET code prior to or after the upgrade - after observing the first exception I upgraded from SDK 1.5 to SDK 1.6 using http://thwack.solarwinds.com/thread/39001
Below is the detailed exception (traced into the InfoProxyService.Read() method where it seems XML is parsing 'False' as a Boolean and throwing the error - and some example code that generates the same exception I'm seeing in my production applications.
Any ideas?
System.InvalidOperationException was unhandled
HResult=-2146233079
Message=There was an error while trying to deserialize parameter http://schemas.solarwinds.com/2007/08/informationservice:ReadResult. Please see InnerException for more details.
