Using Selenium to scrape from Azure web app - asp.net

Question

I have successfully used Selenium from the localhost on my PC and retrieved data from the target URL but I need to be able to do this from a web app hosted in Azure. The problem I encounter is the message that ChromeDriver.exe cannot be located. If I look at the results of my build, there is a copy located in the bin folder but I don't know if this is published to the server and how I would tell the server where it was.
If the app could find the ChromeDriver, I anticipate the next error would be 'cannot locate binary'. I have commented out the binary location because I don't know how I would make Chrome available on Azure.
I can't find any examples of anyone else employing the same environment. I include a code extract.
