Create a VB.NET HTTPClient call from Curl information

At [login to view URL] there are instruction to use their new API system but the instruction are very basic. I need it written in an VB.NET HTTPClient call like on [login to view URL] For you task I need for you to produce a VB.NET function that passes the payload of { "criteria": { "org_names": [ "EMORY UNIVERSITY", "JOHNS HOPKINS UNIVERSITY", "NEW ECHOTA BIOTECHNOLOGY, INC.", "UNIV OF NORTH CAROLINA CHAPEL HILL" ] } } and gets a return. I will parse the return. I've included my current function. It just needs to work.
