Okay so it appears in the last week or so my Enterprise Visual Studio 2017 can no longer get the 'Events' to populate at all for the Diagnostics tool. The tool shows up and runs just fine, it however does not have any events even as I can see and when clicking the filter. Except funny enough it can load symbols and still hit breakpoints and even tell me: "Yep I got your breakpoint event". The problem being I used it a lot for ADO.NET and data tracking to double click an item and get the 'historical debugging'. Basically the 'Filter' says I don't have events yet and even if it hits a breakpoint it only acknowledges the one event.
Things I have tried:
I tried suggestions on this thread: Visual Studio 2015 diagnostic tools no longer working
In your screen shot, it just has the break events, no IntelliTrace Events.
(1) Please add a breakpoint in your app, and then debug it, after the breakpoint was hit, check the Event.
(2) I think you could enable the IntelliTrace under TOOLS->Options->IntelliTrace, please enable IntelliTrace. Debug it again.
(3) Of course, not very sure that whether it is related to the project type, for example, just create a simple Winform app, test it again.
