Creating and updating issues in jira via API using VB.net 2013

Good Day Team,
We would like to create and update issues into Jira via API. So far we have tried this using Postman and this has worked.
We would like to know on how can we do the same with VB.net 2013 framework 4.5?
and if there are any other Tools we can use.

Thanks,
Swarna
