The reason for the error caused by OnInspectorGUI estimates because I write, but the problem is I don't mount the code to the object will appear this problem,,

Loading the assembly failed: "Assets/Scripts/AddComponent/Dll/Microsoft CSharp. Dll"
This error is when I call the dynamic tips I lack anything, I'm from. NET4.0 copied, copied to the project directory later can use dynamic, can be used normally, but sometimes the error, temporarily didn't see,


Does anyone know how to solve it
