Assuming this work is carried on by another team, we would like to pass on some wisdom.

The idea of writing a semi web-app inside the toolwindow was not the best idea as you cannot load libraries in directly. (also we cant use the argument of being offline since, for some reason the cdn is still needed)

Instead, you can create an online website separate from visual studio.

This will allow you to use libraries properly and give a lot more flexibility when adding other code generators (eg C for intel threading library) .

The great news is, it is a simple fix - just replace the function calls the blockly adapter with HTTP Post requests. If you want you can even create a second adapter class for the web and localhost etc

Praying for your successes and hope this message finds you well
