  ""amount"": 0.43422189,
  ""datetime"": ""1517049417"",
  ""id"": 844079167,

Thanks, let me take a look and try to reproduce.

[calloncampbell]

Are you able to reproduce with the ReflectInsight NLog sample?

[Gdocal]

yes, but let me clarify, these errors doesn't throws up to caller code. I just noticed issue in ReflectInsight Live Viewer and in VS output. In viewer instead of seeing expected data I seeing "Internal Exception:[NullReferenceException->Object reference not set to an instance of an object.]"

So to see more information about errors I enabled 'Break When Throw' in VS (Exception settings) for NullReferenceException and SecurityException exceptions.

[calloncampbell]

Thanks for clarification. What version of ReflectInsight viewer are you using?

[calloncampbell]

I'm not seeing the same issue. I'm running the above code inside the ReflectInsight NLog sample app and I updated to the same NuGet package versions listed above:

Can you provide me a screenshot, which version of Visual Studio and ReflectInsight you're using.

[Gdocal]

hm. VS 2015 Live Viewer 5.7.0

I don't know why exception didn't appear in output window. Maybe because I use 'Break When Throw' option

[calloncampbell]

Thanks, ok let me work with this.

[calloncampbell]

I quickly just noticed in your app.config the NLog section is commented out. Could be culprit.

When I get home I'll debug with your configs and see whats up.

[Gdocal]

Thanks. Code works fine everywhere in my project. I noticed issue only in one function which use dynamic variable. So probably it is something specific to dynamic

[calloncampbell]

No luck. I've modified the sample NLog application with your code and configuration and ran it on another machine which has VS 2015 and ReflectInsight Viewer 5.7.0. App runs and logs without issues.

1. Can you send me the full exception stacktrace that you see in the ReflectInsight log.
2. Can you tell me where on your computer (folder path) your code is running.
3. Can you try running the NLog sample I have in repos "reflectinsight-samples" and use branch "testing-dynamic-content" and let me know what results you have.
4. Are you able to try your app on another machine?

Thanks Callon
