Visual Studio .NET Debugger Does Not Stop on Breakpoints When You Debug ASP.NET Pages


When you debug ASP.NET applications in Visual Studio .NET, the debugger may not stop on breakpoints.


This problem occurs because ASP.NET debugging is not enabled on the application.


To resolve this problem, follow these steps in Visual Studio .NET:
1. In Solution Explorer, select the project name.
2. From the Project menu, click Properties.
3. Click to expand the Configuration Properties node.
4. Under Debugging, in the Enable ASP.NET Debugging list, click True.

Hi Swapneel,

The other solutions you can try to resolve the same problem are as follows
1) Check the web.config file of your applications and see whether debug attribute of compilation node of System.Web node is set to "true" or "false". If it is set to false then set it to "true".
2) Delete ASP.Net temporary files from C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files
3) Right click on solution in Solution Explorer, select Configuration Manager, a window will be opened, Make sure Active solution configuration ia set to Debug. Because Release mode removes the pdf file which contains the debugging info.

I had the same problem.
In my case the cause was Internet Explorer 8.
Try closing down all instances of IE8 and then run through the debugger.

The below link gives suggestions to more permanent solutions.

I had the same problem.
Internet Explorer 8 has some issue with visual studio.
Try closing down all instances of IE8 and then run through the debugger.

Also check in web.config file
