- Type or namespace could not be found even after AddReference: There are a few potential causes - 1) Dynamic assembly won't work e.g. Single Executable option in publish; 2) Be careful you are actually passing the assembly reference to AddReferences() not as the third "global" object to CSharpScript.RunAsync(); 3) During publishing, might want to "Delete existing files" because old assemblies can mess up with assembly references.
- By the way the differences between "Add" and "With" is the latter replaces everything, while the former adds to the list; And "Imports" is equivalent to "using" in code.

All prices negotiable; LIST PRICE MAY CHANGE (and become higher); Most of my books are either new or almost new because I always keep my books in very good conditions. Some even have insightful notes.
