Default Basic Streaming Problem

I have decided to make an attempt at coding in the Streaming API and have run into a basic startup problem.

I have followed these steps listed successfully up to Step 4

1. Navigate to
2. Download schema file from ESASwaggerSchema.json and save this to your computer.
3. Selection File > Import File
4. Choose the "ESASwaggerSchema.json" file > Generate Client > Select your required language to generate a language binding.

I have got to "Select your required language" and not sure which one to select as "VB" is not listed, only C# and "swagger_json"
seem to be close.

I would appreciate someone pointing me in the right direction as to which to select,
cheers Les
