You need to enable "Silverlight" debugging in the web project.

Open the "Properties" of the web project and goto page "Web". In the section "Debuggers" check the Checkbox "Silverlight".

Another problem could be, that your current build configuration is set to "Release". Change it to "Debug".

This behavior can be caused by XAP file being opened (in some ZIP viewer) while building your solution. Visual Studio is quiet about not being able to replace the old XAP with new one and your breakpoints will be "out of sync".
