Json serialization

[Slother]

I have lots of experience with .NET and C# under Windows but I'm totally new to KSP addon development and also to Mono. This got me into a situation I don't quite understand

I want to develop an addon which communicates with a REST service on a server. The server is written in nodejs and responds with json formatted data. To test the communication without always waiting on KSP to start up I wrote a separate little console application and everythings works great.

Now moving to an actual KSP addon I get an exception and the confusion starts:

[Exception]: FileNotFoundException: Could not load file or assembly 'System.Runtime.Serialization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

I use the DataContractJsonSerializer type to (de-)serialize json data, which is causing the CLR to look for the System.Runtime.Serialization assembly. Looking at KSP_Data\Managed I realized that this assembly is in fact missing.

What are my options from here?

Mono has an implementation of this assembly but I don't know in what version of Mono it was added and I also can't find out what version of Mono KSP (1.0.2) or Unity (4.6.4f1) is using.

Thanks for any help.

lol, right after posting this I found a working solution, but I'm not quite sure if it is the "correct" or best solution:

- Compile against the .NET Framework 3.5 not 4.0 because the DataContractJsonSerializer was moved from System.ServiceModel.Web to System.Runtime.Serialization in 4.0.

- Copy System.ServiceModel.Web.dll and System.Runtime.Serialization.dll from Mono to KSP_Data\Managed. I copied it from my Unity installation from: Unity\Editor\Data\Mono\lib\mono\2.0

I am still confused by what version of Mono is used and what version of the .NET framework that relates to.

Mono 2.x heavily patched by unity. Use the 3.5 framework, it will do fine

Edit : use a JSon serializer made for Unity like https://github.com/jacobdufault/fullserializer you will have less trouble.

Thanks for the answer.

I thought the least troublesome way would be to use the serializer that is available directly in the framework, but maybe I was wrong

There is also a serializer used by KSP, the ConfigNode class. It's what's used in the save files and settings files, and most mods use it.

Edit: Disregard that, must've read over the part where you said you wanted to comunicate with a server.
