System.Collections.Generic.Dictionary`2[System.String,System.Action].Add (System.String key, System.Action value) (at /Applications/buildAgent/work/b59ae78cff80e584/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:404) CodingJarDLL.Tutorial.TutorialWindow..cctor () Rethrow as TypeInitializationException: An exception was thrown by the type initializer for CodingJarDLL.Tutorial.TutorialWindow System.Runtime.CompilerServices.RuntimeHelpers.RunClassConstructor (RuntimeTypeHandle type) (at /Applications/buildAgent/work/b59ae78cff80e584/mcs/class/corlib/System.Runtime.CompilerServices/RuntimeHelpers.cs:101) UnityEditor.EditorAssemblies.RunClassConstructors () (at C:/BuildAgent/work/7535de4ca26c26ac/Editor/Mono/EditorAssemblies.cs:67)" I don't understand why i am getting them, I think i may have done something with the main camera but i cant remember.
