weird asp.net 'Server cannot access application directory…' error

Question

weird issue with visual studio 2010, right now i'm debugging a web application (which uses sitecore btw) and when entering in certain pages i get this error

Server cannot access application directory c:\svn\foo\trunk The directory does not exist or is not accessible because of security settings.

now the real fun part. c:\\svn\\foo\\trunk is another asp.net project i worked on months ago on this same machine, with the same visual studio 2010, and they happen to both use sitecore too

besides those facts, the projects are absolutely not correlated. i deleted all the project files for foo eons ago

any idea what part of asp.net could be producing this error? what part does even know that i've used to work on this project?!

如果使用符号链接或结点链接，请确保符号链接指向的文件夹仍然存在。

You may want to verify that your hosts file doesn't contain any strangeness, and likewise that your IIS instance doesn't contain any Applications that refer to your old codebase/directories.

Also, try running VS as administrator, and/or setting your user's permissions to admin rights.
