The Eye Tribe

I am using Unity Pro 5.3.4 and OS X 10.10.5. I suddenly started getting a System.Reflection error. I updated to Unity 5.3.4 a couple days ago and everything was working until this morning when I got to work I was getting these errors associated with the Newtonsoft.Json int the Eyetribe/Plugins folder.

The following assembly referenced from This was a file path I removed for privacy reasons/Plugins/Newtonsoft.Json.dll could not be loaded: Assembly: System.Runtime.Serialization (assemblyref_index=6) Version: 3.0.0.0 Public Key: b77a5c561934e089 The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (This was a file path I removed for privacy reasons).

Could not load file or assembly 'System.Runtime.Serialization, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The following assembly referenced from This was a file path I removed for privacy reasons/Newtonsoft.Json.dll could not be loaded: Assembly: System.Xml.Linq (assemblyref_index=5) Version: 3.5.0.0 Public Key: b77a5c561934e089 The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (This was a file path I removed for privacy reasons).

I was able to fix the errors above by putting System.Xml.Linq.dll and System.Serialization.dll in the folder with the plugin. I was not able to find these on my Mac system though. I had to copy it from an installation of Unity on Windows. It just seemed like MonoDevelop couldn't find what it was looking for. I don't know how to fix the following error.

I believe this was answered in this thread.

This will be better documented in the next EyeTribe C# SDK release.

I recommend using the unity example as basis for your project.

Thank you for your response. I had already updated that setting. There are known issues with Newtonsoft.Json in Unity I guess.

This issue kind of mysteriously went away just like it came.

To elaborate, the Newtonsoft.Json uses reflection which is not part of the .Net 2.0 subset default setting in Unity. Hence the change is needed.
