I'm working on bunch of projects, all on .net Core 2.0 / Standard 2.0, that require making Web Services calls. WS calls are made through proxy generated from a Connected Service reference. I've been working on these projects for an year+ and have been using Fiddler regularly. I'm on Windows 10, VS 2017, latest version of Fiddler 5.0.20181.14850.
I don't know exactly what changed recently (there were OS updates, VS updates, etc). But, WS traffic is no longer captured in Fiddler. Anything else to HTTP/HTTPs endpoints are captured. Even if I make a call to the WS endpoints with just a HTTP WebClient class, from code, it shows up in Fiddler. This is true to .NET Core Web API projects, Console app projects and XUnit Test classes.
I might be able to resolve this by pointing the code to the Fiddler proxy. But, given that this has worked for so long, I want to understand what happened and possible resolve it without going the proxy path.
Any ideas would be appreciated.
