c# - Error deleting folder 'bin'. The system call level is not correct

Question

What does this error mean and how do I solve it?

visual studio 2010,
windows 7,
in case it matters.

I tried closing and opening the solution but it still won't delete.

Thanks!

This is an issue that Microsoft isn't going to fix, according to this post: http://connect.microsoft.com/VisualStudio/feedback/details/508695/cannot-delete-the-bin-folder-from-solution-explorer

They were going to make the error message more intuitive but I guess that didn't happen.

Update:

Microsoft has since deleted this page. Here is a cached copy: https://web.archive.org/web/20130825001252/http://connect.microsoft.com/VisualStudio/feedback/details/508695/cannot-delete-the-bin-folder-from-solution-explorer

The message from microsoft is as follows:

However, the error message can definitely be smarter. We will not be able to address this in the VS2010 timeframe but I am resolving this as a postpone so that we can consider improving the error message post-VS2010. Thank you for contacting us.
