  1. POasp.net 4.5 custom membership provider configuration throws strange exception
    text
    copied!<p>My web site was initially written in MVC 4.0 RC using VS2010, . I have just downloaded and installed VS2012, and upgraded my project to Dotnet Framework 4.5.</p> <p>In my project I'm using a Custom MemberShipProvider and a custom RoleProvider. On VS2010 it worked like a charm. But now I'm keeping getting a strange Configuration Error:</p> <p>"This method cannot be called during the application's pre-start initialization phase."</p> <p>The "system.web -> membership -> providers -> add" line in my web.config is marked red as the source of the problem.</p> <p>I eliminated the suspicion that the problem has something to do with the migration process, by creating a new MVC 4.0 Project (in VS2012), adding my custom Membership/Role providers, changing the web.config appropriately, and finding that the error reappears!</p> <p>Digging deeper into the problem - I found the following information in the Application Log:</p> <blockquote> <p>Exception information: Exception type: InvalidOperationException Exception message: The pre-application start initialization method Start on type WebMatrix.WebData.PreApplicationStartCode threw an exception with the following error message: This method cannot be called during the application's pre-start initialization phase.
