I was hoping that it would work for me too, as it worked for other people. But, it did not completely work. I could get rid of the alert that it was showing me and hence got an instinct that it will work, but it did not stop at the breakpoints. Am I supposed to detach the process after putting breakpoints or before that or it doesn't matter? Interesting, any idea how to stop VS from automatically attaching? Scott Scott 2 2 bronze badges. Thank you, this worked right away, I had tried almost every other suggestion.
I ran the VS Update 1 installer again, with the "repair" option, and it fixed this problem. This worked for me. I applied VS Update 2 without having Update 1 installed and it also fixed the issue.
Someone suggested that running this in an elevated command prompt would do the trick: regsvr I ran: regsvr This was on Windows 7, 64 bit, VS Premium.

I tried all of the above except downgrading to IE9 , obviously to no avail. I had a hunch that VS Update 2 might fix the issue, and I was right.
No cmd , no re-installs, no re-boots. I hope it helps someone else too. Oundless Oundless 5, 4 4 gold badges 29 29 silver badges 31 31 bronze badges. I also was using exact same config. I also downgraded to IE9, and nothing worked. Everything I did was out of success: regsvr Alezis Alezis 2, 2 2 gold badges 23 23 silver badges 31 31 bronze badges. In VS for sure there is not that dropdown, but maybe trying to repair could be a fix. I did try and repair the VS installation - without success in fixing this issue.
I have since uninstalled IE10 due to some gross incompatibilities of our existing code base. I finally fixed it by downgrading to IE 9, to wit: Type "appwiz. Debugging works again. MonteChristo MonteChristo 1 1 bronze badge. This is what I ended up doing and will mark this answered - seems kinda funny. Please remove 'Accepted' mark from this answer. As bill berlington mentioned - this is NOT a solution. If I suggested you to stop using Win7 and VS, would you accept it? The regsvr32 answer provided by Dmitri actually fixes the problem, or at least has a high likelyhoodof fixing it worked for me.
Please mark that as answer. Yes the regsvr32 fix is the ideal fix: You get IE10 and a working environment. You may hit the breakpoint in either a transpiled. Either way, you can step through code and examine variables. If you need to break into code in a transpiled JavaScript file for example, app-bundle.
If you need to break into code in a TypeScript or JSX source file and are unable to do it, use Attach to Process as described in the previous steps to attach the debugger. Make sure you that your environment is set up correctly:.
You closed all browser instances, including Chrome extensions using the Task Manager , so that you can run the browser in debug mode. Make sure you start the browser in debug mode.
You can do this manually in the source map file which is helpful for testing or through a custom build configuration. For more information, see Generate source maps for debugging.
Alternatively, if you need to break into code in a source file for example, app. Visual Studio has the capability to use and generate source maps on JavaScript source files. This is often required if your source is minified or created by a transpiler like TypeScript or Babel. The options available depend on the project type. A TypeScript project in Visual Studio generates source maps for you by default. For more information, see Configure source maps using a tsconfig. In a JavaScript project, you can generate source maps using a bundler like webpack and a compiler like the TypeScript compiler or Babel , which you can add to your project.
For the TypeScript compiler, you must also add a tsconfig. For an example that shows how to do this using a basic webpack configuration, see Create a Node. To configure advanced settings for source maps, use either a tsconfig. To enable debugging using Visual Studio, you need to make sure that the reference s to your source file in the generated source map are correct this may require testing.
Specifically, when you correct this for debugging purposes, the reference to the source file such as app. The following example shows how you can configure source maps in webpack, which is one of the most common bundlers, so that they work with Visual Studio. Webpack only If you are setting the breakpoint in a TypeScript of JSX file rather than a transpiled JavaScript file , you need to update your webpack configuration.
For example, in webpack-config. For complicated scenarios, the browser tools F12 sometimes work best for debugging, because they don't require changes to custom prefixes. If you add a tsconfig. A tsconfig. For more details about the compiler options, check the page Compiler Options on the TypeScript Handbook. However, you cannot automatically hit breakpoints on files generated with Razor syntax cshtml, vbhtml. There are two approaches you can use to debug this kind of file:.
Place the debugger; statement where you want to break : This causes the dynamic script to stop execution and start debugging immediately while it is being created. Load the page and open the dynamic document on Visual Studio : You'll need to open the dynamic file while debugging, set your breakpoint, and refresh the page for this method to work.
