TypeLoadException w/ Mono 4.2.3 about serilog.exceptions HOT 19 CLOSED

The ground has shifted again.

netstandard 2.0 will add support for Mono. If we target that, then Mono support will be assured and we won't have to do reflection in SqlExceptionDestructurer. I say we wait for official Mono support.

Also, by then xproj to csproj will be complete, and the Tooling bug stopping our Travis CI builds from successfully running xUnit tests on Mono will be fixed.

Thanks for posting this. There is no P/Invoke in Serilog.Exceptions.

Probably this is caused by ExceptionDestructurer because it contains a list of all the exceptions with just the default Exception properties. One of the Exception types in that long list may not be supported on Mono?

Unfortunately, the exception you posted does not list which type is causing the problem. If you would like to test this, you can grab the Serilog.Exceptions project and try debugging it directly, rather than using the NuGet package.

Hey thanks! I'm trying to compile from source on Linux, and I'm running in to some issues there too. I have to run now so I figured I'd post my progress to see if it shed some more light. First, I had:

/home/matt/serilog/Serilog.Exceptions/Source/Serilog.Exceptions/Serilog.Exceptions.xproj: error : /home/matt/serilog/Serilog.Exceptions/Source/Serilog.Exceptions/Serilog.Exceptions.xproj: /home/matt/serilog/Serilog.Exceptions/Source/Serilog.Exceptions/Serilog.Exceptions.xproj could not import "$(VSToolsPath)\DNX\Microsoft.DNX.Props"

So I found the following post: travis-ci/travis-ci#5164 and followed the instructions here: travis-ci/travis-ci#5164 (comment)

So now I try to build your project.json file, with the following result:

Feel free to reopen if you need me to do anything.

So after some search it seems that the following exceptions can't be loaded on Mono:

• System.Diagnostics.Eventing.Reader.EventLogInvalidDataException
• System.Diagnostics.Eventing.Reader.EventLogNotFoundException
• System.Diagnostics.Eventing.Reader.EventLogProviderDisabledException
• System.Diagnostics.Eventing.Reader.EventLogReadingException
• System.Management.Instrumentation.InstanceNotFoundException
• System.Management.Instrumentation.InstrumentationBaseException
• System.Management.Instrumentation.InstrumentationException

They are all from System.Core which I think is in Mono 4.0, but I think that these types aren't part of Mono for now.

Is it possible to exclude them on Mono?

from serilog.exceptions.

I'm not sure. Presumably we could use a pre-processor directive but I'm not sure how to do this in the new project.json world. Any ideas?

from serilog.exceptions.

I am not sure this is possible.
But following the netstandard mapping to platforms, if you add another target to netstandard1.2 mono should be covered.

from serilog.exceptions.

Have you tested that? Would you be willing to submit a PR for the above?

from serilog.exceptions.

I haven't, I am not at all familiar with netstandard.

from serilog.exceptions.

So I've tried but ended with nothing, this was a dead-end: System.Core isn't supported by any netstandard targets.
And after some though I don't think having a mono target can help: for example my application target .NET 4.5, which is supposed to be largely compatible with mono, so when the build is fetching the nuget Serilog.Exceptions package, it's the net45 which is referenced no matter what.

So I think that the only solutions until Mono supports these types are modification in applications/libraries wich reference Serilog.Exceptions:

• define a MONO pre-processor directive which exclude the call to Enrich.WithExceptions().
• override the destructurers and not include the ExceptionDestructurer, but define a new one which includes only types compatible with all platforms.

Sorry for the bothering.

from serilog.exceptions.

Thanks to http://apisof.net I can confirm that these types are only available in the full .NET Framework.

from serilog.exceptions.

Perhaps we could check if these types exist in the assemblies and only add them if they do?

from serilog.exceptions.

Excellent idea! 😄
I was so focused on pre-processor directive that I haven't think of that.

from serilog.exceptions.

@laedit So I created a Travis build here but it's failing. The errors suggest that there are other types not supported on Mono. Is this correct?

from serilog.exceptions.

Strange, the 'EventSourceException' should have fail my test.
Apisof.net confirm that it doesn't exists on Mono.
I will look into it tomorrow, I can't do it right now.

from serilog.exceptions.

Cool, looks like it was worth investing in Travis CI.

from serilog.exceptions.

Yes, that was an excellent idea 😄

I have tested the use of the new version of Serilog.Exceptions on a Travis build and it passed.
The difference is that I always install the latest version of mono and in your config you specified the version 4.2.3.

So if you want to support that specific version, I will add EventSourceException and SqlException to the types not handled by mono.

from serilog.exceptions.

I just tried 4.4.2 here and according to this thats the latest release version. Still failed.

from serilog.exceptions.

Ok, so I honestly don't know why it is working on my test project.
Nevertheless, I will test all types with apisof.net to see if there are other that I missed.
