.NET 4.7.2 is required to run DotNetBackendOAuth2

[CaspianCanuck]

I ran into a weird problem trying to run DotNetBackendOAuth2 against a Cloud Edition ION API. The RequestToken call would fail when I ran the project under .NET 4.5, but once I switched to 4.7.2 the error went away on its own.

Thanks CaspianCanuck for posting this --I wish i found it 2 days ago :)

Confirming same behavior.

+1 to this, can confirm is still an issue. General socket failures/exceptions with .NET 4.5, but the examples run without issue with .NET 4.7.2.

No error message is given regarding incorrect framework, just a stack-trace listing a 'socket forcibly closed by remote host' message, which lead me to believe that there was something wrong with the addressing/etc.
