I am trying to configure visual studio to enable me to step into the .net framework source code when I am debugging.
I have tried with both Visual Web-Developer-Express
I had this problem - no symbols loading - and spent a week trying to solve it. My problem was that I had for the first time started using Master pages in my website project. And I was incorrectly creating the content pages; the error was that i was not indicating the codebehind file in the page directive of the content page so my codebehind file was in essence unconnected to the build of the project. A dumb mistake and simple fix after a week of frustration. Hope this helps some lost programming soul stuck with the same problem.
