Tonight I was doing some development on a ASP.NET Web Forms app I'm writing at home. It was causing some problems and I wanted to see the HTTP traffic so I brought up Fiddler2 to give it a try. But the instant it came up it complained about something that it thinks I need to do on my Windows 10 machine. I don't know nor understand what it is, and since I was running out of time and needed to get on with other things, I closed the dialog box, did some more work on the app and tried to check it into to my repository on Visual Studio Online (VSO).
That's when things started to go badly for me. I couldn't check anything into VSO. VSO thought I wasn't event connected to it. It gave me an access error, something like "TF30063 Access denied". Now I'm trying to shut down my machine to go to bed, and I discovered that Fiddler was still up and running. I wasn't even aware that it was still up.
So my question is this, does Fiddler2 interfere with VSO? It certainly looks like it might, as I think this is more than just a coincidence that I was having this problem, I've never had this problem in the months that I've been using VSO and Fiddler2 was running in the background.
