Nancy.Serialization.JsonNet.dll not loading in Production

[ilopez]

I've got a very weird situation. Obviously on my development machine Nancy.Serialization.JsonNet loads properly in my project.

However, in production Nancy.Serialization.JsonNet does not load.

I can confirm the assemblies loaded using Sysinternals Process Explorer, and my initial review of the FusionLogs in production do not indicate a problem. However, I do have a "Total # of load failures" count of 1 in production, and 0 in development.

I'm not expecting a solution to this, at the moment; just putting something here for the google gods for the other poor souls who have to spend 5 days tracking this down.

I've tried upgrading the project to .NET 4.6, down to 4.0, nothing.

I think I'm going to have to manually return JSON strings, and manually handle them in my client library for now. Bummer!

Hmm. You're not giving us much to work with here... Is there anything that makes you think this is a problem with the assembly itself? Something that we can fix on our end?

@khellang - I definitely recognize that this is going to be tough to diagnose, so I put the issue up to see if anyone else has this problem. Close it if you'd like, but it definitely was a weird situation.

@ilopez Were you ever able to figure out this situation? Think I may be running into the same thing

@wootencl Hey, yep I ended up returning my responses as manually converted Json Strings after passing my return objects through JsonConvert.Serialize().

It never happened again on another system. It was (from what I remember) a clean install of Windows Server 2012, so nothing really should have stopped the load.

I even tried to troubleshoot the Fusion logs, but couldnt figure them out. I ran out of time to fix it properly, so that is why I just returned strings.
