I recently upgraded from VS 2017 to VS 2019.
In VS 2017, when running an asp.net application locally, using Chrome, I could put a breakpoint in javascript code and the debugger would stop on the breakpoint. This no longer works in Visual Studio 2019.
What do I need to do to enable javascript debugging in Visual Studio 2019 using Chrome? I would like to be able to put breakpoints in javascript files and have them hit.
Here is my setup.
I've enabled Javascript debugging.
I put a breakpoint in my Javscript code. This breakpoint is in a *.js file (not inside a Razor view).

Click the JavaScript Console, Call Stack, Watch 1, Locals, Output and Breakpoints items in turn so they are all open at the bottom of the Visual Studio window. Activate the JavaScript Console window by clicking its tab.
To set a breakpoint in source code: Click in the far left margin next to a line of code. You can also select the line and press F9, select Debug > Toggle Breakpoint, or right-click and select Breakpoint > Insert breakpoint. The breakpoint appears as a red dot in the left margin.
If a source file has changed and the source no longer matches the code you're debugging, the debugger won't set breakpoints in the code by default. Normally, this problem happens when a source file is changed, but the source code wasn't rebuilt. To fix this issue, rebuild the project.
It should work in VS2019+Chrome.(I just checked this in several machines)
This is not one issue can be resolved directly since many factors can cause this behavior, you can follow suggestions below to check if it helps:
1.Update your VS2019 to latest 16.3.7, update your chrome browser to latest 78.0.3904.87
2.Delete the bin and obj folders in your project directory => then close and restart VS => open that project and do a clean rebuild
3.Make sure you're in debug project mode, right-click your web project=>Set as StartUp project
Also, sometimes we need to wait for several seconds before the debug session starts successfully.(I once met same popup, then after several seconds it disappeared and everything worked)
Hope it helps :)
