Method 1

It worked for me. Try this.

First try rebuilding your project by right mouse click the project > Rebuild If that doesn’t work, try a clean of the project (right mouse click on the project > clean)

If that didn’t work check this:

Right mouse click your project
select [Properties]
select the [Build] tab
make sure [Define DEBUG constant] and [Define TRACE constant] are checked
Click the [Advanced] button at the bottom of the Build tabpage
Make sure that [Debug Info:] is set to [full]
Click [OK] and rebuild the project ;-)

Hope that works for you! (step 6 generates the .pdb files, these are the debugging symbols)

Method 2

Some times this occurs if the sourcecode is been copied from the network folder, it messes up the symbol settings. Below solution works for me everytime

• In debug mode, select debug->windows->modules
• Check your dll symbolStatus . Make sure that it is loaded into
  the project (i am sure now the status
  is not loaded )
• Right click your dll, click symbol settings.
• And manually add your symbol path (.pdb file path)
• And again right click the dll, and click load symbols

Hope this helps

Method 3

Have a look at these articles

• Why would the debugger not be
  stopping at a breakpoint in my
  ASP.NET application?
• Why does Visual Studio sometimes not
  go to my breakpoints?
• Reason for VS.NET ‘current
  breakpoint will not be hit’
  warning?

Method 4

That suggests the build that’s running doesn’t match with your code.

Try performing a “clean”, make sure that you’ve stopped any previous debugger sessions etc, then rebuild and retry.

Method 5

make sure there are not instances of w3wp.exe running. I had several and closing them fixed it for me.

Method 6

Visual studio repair solved the problem for me

1. search for visual studio installer in start
2. select more option for the version you are using and click repair.

Method 7

In my i changed the connection string but in the browser it was referring to old string so i just did ’empty cache and hard reload in chrome browser’ and it worked

Method 8

This problem occurred to me when I had copied the project. In fact, by opening the old code file if breakPoint is inserted, you will see that it will work. So learn the correct copying method.
