POVS 2010 fails debugging: HttpException invalid file name for file monitoring in LoadControl
text
Body
copied!<p>I've really been struggling for days on this matter.</p> <p>I have migrated a asp.net 3.5 project in VS2010 to a asp.net 4 project. Everything worked fine for several weeks.</p> <p>Somehow, I get a strange error since a few days. To clarify what this project looks like:</p> <p><strong>The Application</strong></p> <p>It's a UserControl based application and the app areas are composed of nested UserControl Hierarchies, that load their children Controls in <code>OnInit()</code>, in order to get the event system to work.</p> <p>(Note: everything works great in VS2008 and .net 3.5!)</p> <p><strong>The Error</strong></p> <p>Now when I start debugging the webapplication in VS2010, sometimes (!!!), a HttpException is thrown, with the message:</p> <blockquote> <p>Invalid file name for file monitoring.</p> </blockquote> <p>in <code>LoadControl()</code><- and now it gets interesting, the parameter for LoadControl is a ~/ prefixed UserControl-Path eg. ~/Controls/Home/Partial.ascx BUT in the Exception it is shown as a Directory, somewhere in the Controls Directory.</p> <p>Probably VS uses such an approach to internally track changed files to reload?</p> <p>Has anyone encountered the same issue? If so, have there been any solutions?</p> <p><strong>Edit</strong>: when deploying the webapplication, the error vanishes. It only occurs when debugging. I have currently disabled HttpExceptions in the debug->exceptions menu. But i would be very glad to catch those again too ..</p>
