Nice error

Can you give some info?

[genemars]

sure, what kind of info do you need?

[genemars]

The problem seems to be around the Type.IsDefined:
https://github.com/NLog/NLog/blob/master/src/NLog/Config/MethodFactory.cs#L100

[genemars]

the hosting platform is a BananaPi with raspbian os (debian derivative):

Which NLog version is this? Did it work with other versions before?

It mono I see? Do you use the tge nuget package?

[genemars]

I tried nuget package 4.1, 4.0, also build from latest source. All of them same issue.
But I suspect this is a mono-arm bug, because everything is running fine on my ubuntu x64 pc.
If I delete the NLog.config file, the problem disappear and the application starts (without logging infos though).

[304NotModified]

Yes, I never have seen this issue before. Is it an other mono version?

[genemars]

mono is the same, just running on different architecture:
Architecture: armel,vfp+hard
that are kind of SOCs used in mobile phones and little pc like Raspberry Pi.

[genemars]

this is what I have in the config file:

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <targets>
        <target name="debugger" xsi:type="Console" layout="${longdate} ${level} ${message}"/>
  </targets>

  <rules>
    <logger name="*" minlevel="Trace" writeTo="debugger" />
  </rules>
</nlog>

[304NotModified]

Can you also provide an internal log (DEBUG)?

It's a bit strange as RegisterType in ScanTypes is wrapped with a try catch. Our is this not the full config?

[304NotModified]

and please test with NLog 4.1.1, which logs some more stuff :)

[genemars]

NLog was not starting at all, but MONO_LOG_LEVEL=debug suggested that there was a missing dependency, so I solved the issue by installing it:

sudo apt-get install libmono-system-servicemodel4.0a-cil

[304NotModified]

Good to hear it's solved!

I can see in the stacktrace that's was already logging to the internal logger. So if someone has a similar issue, check https://github.com/NLog/NLog/wiki/Logging-troubleshooting#internal-logging
