Invoke code knowledge base

Is there any good reference links for invoke code ? I mean not for ‘invoke code’ activity.

Most of the times I keep seeing some code snippets in the forum here and there and want any good reference links on the code used. I some times refer to below links and please let me know if anyone has some concise reference links.

Thanks in advance,

Hi @viswanarahari,
