I tried a bunch of different methods suggested in stackoverflow, but none seemed to have worked except to make additional changes to global.asax to force VS to recompile the code. I believe what may have caused the problem is that I was updated global.asax while I was still running the application in debug mode. Normally this is not a problem, but may be a timing of when I updated the code while the page was refreshing.
2. After the problem above, I had issues with intellisense in code-behind not recognizing objects in the aspx page. The red squiggly line comes up, but I am still able to compile and run the application with no compile errors. If I type out the object name, intellisense will not find the object.
Restarting VS fixed this problem. I do not know what caused this as I have restarted VS several times to fix the problem above. Either the problem came up after the fix above, or somehow keeping the files open when I closed VS before restarting somehow fixed the issue.
