Download a Binary REST Response into BinData

See more REST Examples

Demonstrates Rest.FullRequestNoBodyBd, which sends a request with no body and stores the binary response body in a BinData.

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.
