StructureMap Exception in .90 on II7 on Win 7

Now l'm not really a web developer -- and this my first attempt to use IIS7 or Windows 7 ... but I just happened to have the Win7 beta installed at home, so I ran the Web Platform Installer to get everything set up and grabbed the 0.9 source, compiled and publishing to my local machine.

Your wizard installer said that PUT and DELETE weren't working right ... but when I continued, it brought up the site okay, and the categories like "blog" work okay.  However, when I try to click on an individual item to view it's page, eg: http://localhost/blog/2009/03/08/WelcomeToAtomSite09.xhtml ... I got the following error message. I've included the stack trace etc.

Server Error in '/' Application.
StructureMap Exception Code:  200
Could not find an Instance named "OpenIdModalWidget" for PluginType AtomSite.WebCore.IWidget
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

It sounds like the OpenIdPlugin could not install it's resources.  Did the write access check during the wizard complete ok?

You could temporarily disable the OpenIdPlugin in the service.config file and restart the application.

    <plug:type>AtomSite.Plugins.OpenIdPlugin.OpenIdPlugin, AtomSite.Plugins.OpenIdPlugin, Version=, Culture=neutral, PublicKeyToken=null</plug:type>

If that fixes things, you could try forcing a re-install of the OpenIdPlugin by setting installed to false and enabled to true.  

Also, you should check the log files to see if there are any errors.  The log files are located in App_Data.

This turned out to be a filesystem permissions problem... Somehow my Windows 7 IIS defaulted to using a built in account which did not have full access to the wwwroot folder.
