Windows – How to disable Javascript Debugging in IE11

internet explorervisual studiowindowswindows 8windows 8.1

I am building an ASP.NET Web Forms application (not site) and whenever I debug with Internet Explorer, I cannot seem to disable the integrated Javascript debugging with Visual Studio 2013 Pro.

How do I get it to stop breaking on Javascript exceptions?

My OS is Windows 2012 Server R2 (so, equivalent to Windows 8.1 Pro) with IE11. I have tried every setting that I could find but nothing has worked so far. I have even logged out and back in. I am going to try a complete reboot right now.

The screenshots below show all the settings I've tried.

The options in VS for exceptions to determine if the debugger should break on an exception. Though VS will always break on an unhandled exception and a language break (debugger). The options do not stop the script debugger from being attached when you launch IE from VS.

The options in VS to enable or disable JIT debugging change just the just-in-time debug feature. Enabling JIT debug simply means that if a running application not launched by VS hits a break condition the user should be prompted if they want to attach VS to debug the application. This also don't change if script debugging is enabled when you launch IE from VS.

The options in Internet Explorer to disable script debugging only changes if IE should run with debugging enabled always. In IE11 with VS2013 this feature is never needed but is there to support older versions of VS.

The easiest way to get the behavior you want is to do:

Right click on a aspx/html file there is a ‘Browse with…’ item. This will bring up a dialog to configure your browser.

Click the Add button. Add something like:

    Path: c:\Program Files (x86)\Internet Explorer\iexplore.exe 

    Friendly name: Internet Explorer (no debug)

Set that as your default

Windows – No Internet access on Windows Phone 8 emulator (despite working connection in Windows 8)

The Windows Phone 8 emulator runs in it's own (Hyper-V) VM with it's own networking and MAC addresses.

Using the Hyper-V Manager --> Actions --> Virtual Switch Manager, check the setup of the virtual switch; I believe that by default it's set to "Internal network" which mean no outside access.

"An internal virtual network is not bound to a physical network adapter. As a result, an internal virtual network is isolated from all external network traffic."

enter image description here

Since you say you have no router and just plug the host directly into the ISP's network to get Internet, you'll need to figure out a way to share the network connection. Either by changing the virtual switch setup to bind to an actual (extra) physical adapter in the host, which is then hooked into a router or alike (to split the network connection from the ISP), or by keeping it as "Internal Network" and then enabling Internet Connection Sharing on the host (so it acts as a router).

enter image description here
