ServiceStack.Text | .NET 's fastest JSON , JSV and CSV Text Serializers | JSON Processing library

In search for a scripting language for my Unity application I came across SharpScript and the example project (https://github.com/ServiceStack/script-unity) that worked fine. However the example project is more than 2 years old so the language and its implementation had went a long way since then.

So I have updated all the SharpScript related dlls to their latest versions to get the latest version and now my project still works in the editor but it stopped working when built with IL2CPP + .Net4.x Unity settings. The error I'm getting upon the start is this:

I've got following setup: C#, ServiceStack, MariaDB, POCOs with objects and structs, JSON.

The main question is: how to use ServiceStack to store POCOs to MariaDB having complex types (objects and structs) blobbed as JSON and still have working de/serialization of the same POCOs? All of these single tasks are supported, but I had problems when all put together mainly because of structs.

... finally during writing this I found some solution and it may look like I answered my own question, but I still would like to know the answer from more skilled people, because the solution I found is a little bit complicated, I think. Details and two subquestions arise later in the context.

Sorry for the length and for possible misinformation caused by my limited knowledge.

Simple example. This is the final working one I ended with. At the beginning there were no SomeStruct.ToString()/Parse() methods and no JsConfig settings.

I have some JSON text and I want to deserialize it into a Dictionary. ServiceStack.Text does that no problem, until there are brackets inside the string values. Then it decides to deserialize that string, as if it was JSV (ServiceStack's format, similar to json but without quotes).

Here is a simplified JSON example:

I have a case where the ServiceStack JSON serializer fails to deserialize, and where Newtonsoft's JSON.NET manages to do so. I have not found a clear-cut way to replace the default serializer with JSON.NET, so its global and for all classes.

JsConfig.SerializeFn I guess works, but it is per class, and I want for all classes, globally.

How do I do that?

Background

I am using the ServiceStack.Messaging.Redis and Redis as an MQ solution. We use this approach to sending messages:

There is an example of a simple ServiceStack F# application for .NET 4.5:

I am currently using ServiceStack.Text to serialize CSV from a list of objects. I have a model:

I had a plan to connect to a JSON-based API using ServceStack's Routing features for C#. It seems that I get a '422 Unprocessable Entity' when attempting to do so when, in reality I'm supposed to be getting a JSON response. This error message is interesting though, since it repeats itself multiple times over (8 times exact) with the message Could not parse Error ResponseStatus ErrorResponse System.IndexOutOfRangeException: Index was outside the bounds of the array. Full stack trace below.

I've tried many configurations, and there is one that 'works' but removes one of the key needs of the way this route is set up. In this project, I use ICacheClient to save a session key for 5 minutes, so I don't always need to call the API every time I need it. Since ServiceStack uses injection to set my instance of ICacheClient, it must be public. However, if it is public I get that 422 error, but if it isn't public I get a NullPointer because it's reference cannot be set by ServiceStack.

Here's my current setup:

AppHost.cs

I am using a valid license key. But I keep getting this error:

I am working with large json files and memory is a concern. I would like to read one object into memory at a time from file. Is this possible?

In ServiceStack.Text docs it says there is an API using reader/stream

But I can't see how to get that working. The files are too large to deserialize in one go. Is it possible to handle this scenario with SS?

Thanks
