How to import 3rd party dlls?

[hellojiaru]

I copied my dll to the icsharp.exe folder and using it with error "error CS0246: The type or namespace name 'xxx' could not be found (are you missing a using directive or an assembly reference?"

@hellojiaru First of all, I apologize to not to respond to you earlier. Sorry!

When you type in the cell #help command an run it. There will be a message instructing you how to load third-party libraries and scripts in the notebook.

The way to do this is the following:

• You place your dll to either to the same directory where your notebook file is or to the temp folder.

• Then you reference the library like this:
  #r "testlib.dll"

• Then you import the namespace from the folder as you would normally do:
  using TestLib;

• Then you would use your library in the notebook.

I did a short test and unfortunately, this is not working as it should. :(
I will troubleshoot this error and fix it. Will let you know.

Thanks for your patience
