Is this JSON .NET from the asset store or the official release?

 

The official release from Nuget. It miraculously started working. Wish I knew how.

 

If it's working, it's working. But, if you plan to target multiple platforms, I would use my version from the asset store. It's free.

 

I've been using Dustin's JSON .NET asset for a couple of years now and it's great. He's also great on getting back to you if you have any problems. So, like he said, if you are targeting multiple platforms you'll want to get it.

 

Hello Dustin,
I have very similar problem with your asset only when using .Net standart 2.0. The crash throws in windows standalone build. In editor everything works fine.

Code:

Code (CSharp):

1.  
2.             MemoryStream stream = new MemoryStream(bytes);
3.             using (BsonReader reader = new BsonReader(stream)) {
4.                 JsonSerializer serializer = new JsonSerializer();
5.                 var json = serializer.Deserialize<JObject>(reader);
6.             }

Run-time

Code (CSharp):

1. TypeLoadException: Failure has occurred while loading a type.

Could you help me please?

 

We are using @Dustin-Horne's Json.NET for Unity, and we started getting lots of AOT errors during serialization..

It turns out that this only happened with the new .NET scripting backend, .NET 4.x. We changed it back to .NET 3.5 and the AOT errors went away.

 

@glap @AlienMe send me an email: dustin at parentelement dot com. I'll send you both a .NET 4.6 build which should solve all of those issues.

 

@Dustin-Horne I'm facing similar issues, could you send me the .NET 4.6 build?

 

I think the attached package has all of the platform DLLs but only the IL2CPP DLL is .NET 4.6. When you import, uncheck the other DLLs and only import the IL2CPP one. Then in the inspector, select the /jsondotnet/assemblies/il2cpp/newtonsoft.json.dll and change the mapping to All Platforms and save.

I'm working on an update and going to see if I can tackle mixed platforms (.NET 3.5 vs .NET 4.6) with asmdefs. I'll update the GitHub repo with the new projects hopefully in the next 3 weeks and push to the asset store as well.

 

@Dustin-Horne Any progress - and also, what GitHub repo are you referring to?

 

Hi Dustin, I also upgraded to .NET 4.6 (necessary for unrelated reasons and I can't go back) while also moving to Unity 2018.2.x. I was also having this exact same issue. I tried building via IL2CPP build (including going through the process of installing VS 2017 + tools, rebooting, etc), and while Newtonsoft JSON.NET started working, other things didn't (plus the build times really sucked) so I tried one more thing...

I moved back to the Mono build, then I simply reinstalled the package again, but removed all of the assemblies except for the AOT one and then it finally worked for me. Hope this helps anyone else having the same issue.

 

I am getting the same error on Windows standalone build while using the latest asset store version.

It works fine on iOS, Android and in Editor. It errors out on Windows standalone.

 

I think I found the problem. It works when I set api compat. level to .NET 4.x but it doesn't work when I set it to .NET standard 2.0.

Do you think you can fix that?

 

Abandoned?
