Assembly Resolution Exception error which is still unanswered since so many days.

So i have been posting about build error in IOS since many days . But my exception error was still unanswered , it will be a great helpful if someone atleast give a try on this question.

The exception error is as below

AssemblyResolutionException: Failed to resolve assembly: 'ClassLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

Mono.Cecil.BaseAssemblyResolver.Resolve (Mono.Cecil.AssemblyNameReference name, Mono.Cecil.ReaderParameters parameters)

UnityEditor.MonoAssemblyStripping.ResolveAssemblyReference (IAssemblyResolver resolver, Mono.Cecil.AssemblyNameReference assemblyName) (at C:/buildslave/unity/build/Editor/Mono/BuildPipeline/MonoAssemblyStripping.cs:264)

UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)

 

Does no one know about assembly resolution exception?
