VS 2017 - Very slow (laggy) when debugging

Solution 1:

After some additional investigation I found this thread Unchecking Enable Diagnostic Tools while debugging in Tools → Options → Debugging → General did the trick!

Unchecking Enable JavaScript debugging for ASP.NET in
Tools → Options → Debugging → General
makes a huge difference in performance.

Solution 2:

If disable Diagnostic Tools don't fix the problem try to disable IntelliTrace, Unchecking Enable IntelliTrace, in Tools -> Options -> IntelliTrace. Work for me.

Solution 3:

I have tried disabling few things myself just to see what is causing it. The only thing that did work for me is Tools > Options > Debugging > General > "Enable JavaScript debugging for ASP.NET (Chrome and IE)".

I'm using VS2017 Enterprise v15.2 for Asp.net WebForms.
