Script compilation failed.

Also, the exampes for the C# and C# scripts are comletely different. The documentation not only doesn't describe how to create the output binding but adds a lot of confusion.

@toddysm
Thanks for your feedback! We will investigate and update as appropriate.

[mike-urnun-msft]

@toddysm Thanks for reporting this issue and helping us drive improvements towards MS Docs! I've updated the csharp sample demonstrating the output binding with a fix and the changes should be live shortly after the PR merge.

We will now proceed to close this thread. If there are further questions regarding this matter, please reopen it and we will gladly continue the discussion.
