In Visual Studio .NET, whenever I try to debug my ASP.NET application I’m not able to stop the debugger on my breakpoints. Why?

Your ASP.NET project is not setup for debugging.

• Open up the project’s properties window and set the “Enable ASP.NET Debugging” option.
• Open up your web.config file and make sure the Compilation tag’s debug attribute is set to true.

<compilation defaultLanguage="vb" debug="true" />

Make sure the account you are logged in as and the ASP.NET Worker process is in the local “Debugger Users” group.
