unity3d - Unity Standalone Probobuf C# Port -

i'm trying use protobuf c# port developed jon skeet's on unity project, keep getting errors when try build , run stand alone. have copied on .dll files assets , things run smoothly while i'm running unity developer environment, compile , build error "filename unkown".

error image

i haven't managed find solution because seems people run similar issues using marc gravell's version of protobuf. i'd stick version i'm using since working several languages project.

any appreciated.

-- solution --

it turns out had go edit > project settings > player , change net version 2.0 subset 2.0

i find type initialization exceptions occurring because of project reference issues. 2 common causes:

1. building application against newer version of .net library being referenced (e.g. protobuf library may have been compiled against .net 4 while application being built against .net 4.5). try resolving recompiling protobuf libs against same .net version project.

2. the compiler assumes reference present, @ run time not. can fix adding reference specific library (in case .net library regex object, system.dll)
