Send a REST Request with a Binary Body

See more REST Examples

Demonstrates Rest.FullRequestBd, which sends a complete request whose binary body is read from a BinData and stores the text response body in a StringBuilder.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.
