I got the following error while am uisng litjosn any help ?

facing the same issue!! has anyone solved it?

Certain very common libraries do not work properly on hololens (or, it seems on other UWP-platforms).
Your program will run fine in editor, but things will go sideways once you try to compile for hololens or once you run your program on hololens.

That makes using most Json-Serializers a problem, since almost all of them rely on such common libraries.
Even worse is that things that might work on hololens will throw errors in Unity Editor.
The only solution i found was editing such third-party-code with compiler-instructions and a piece of code for Editor and a piece of code for Hololens.

Good luck.
