Windows 8 IIS does not load stylesheets and images in asp.net app

by

I just installed Windows 8 on my computer and tried to load my ASP.net application. The page loads with no problems. But none of the images or stylesheets that are located in the App_Themes directory load. I do have a separate folder that has images in it and they do load. I think it is some security issue but I can’t find out what it could be. If I deploy the site to my dev 2008 R2 box then the site loads correctly, but it doesn’t load correctly on my Windows 8 box.

Why is ASP.NET throwing so many exceptions?

by

By coincidence I watched the debug output of Visual Studio a bit. I can see hundreds and hundreds of various exceptions being thrown. I checked another ASP.NET based solution and it is showing same behavior. Why are all those exceptions thrown? I cannot believe it is good for the overall performance, is it?
Look at the excerpt below. It is the output of appr. 30 seconds surfing. Most are HttpExceptions but there are also FormatExceptions and ArgumentOutOfRangeExceptions. None of these is really affecting the usage. Nothing crashes. Does anybody have an explanation, as it seems to be “normal”?
