visual studio 2017 debug unable to start program Invalid pointer

Question

Debugging an ASP.NET MVC application with the default Chrome browser was working fine. I switched the debug over to start up IE instead to do some additional testing and the debugging worked fine. After I was done with IE I switched back to Chrome and now I get this error. If I switch back to IE I also get this error. I have closed and re-opened solution. I have closed and reopened VS. I have run VS with logging and I get no errors in the Activity Log. I can successfully debug if I turn off "Enable JavaScript debugging for ASP.NET" in the debugging options, but it was working fine with that option earlier. Any suggestions?

Answer 1

Unfortunately information on how the debugging emulator works is hard to come by. The only known solutions are...

1. Reinstall Visual Studio
2. Update Visual Studio if there is a patch/update available.

You can use a different browser or the internal browser.

Answer 2

Go to Tools > Options > Debugging > General and turn off the setting for Enable JavaScript Debugging for ASP.NET (Chrome and IE).

Answer 3

I have also encountered this issue on visual studio 2017 like below:

I have followed below step:

Go to Tools > Options > Debugging > General > Unchecked Enable JavaScript Debugging for ASP.NET (Chrome, Edge and IE).

Once I get rid of check box on Enable JavaScript Debugging for ASP.NET (Chrome, Edge and IE)

Then It works for me and Invalid Pointer error gone!
