最近遇到一个比较棘手的问题，在编译完一个。NET项目后，遇到如下出错信息
After you compile your Web application, you may receive the following error messages in
the Microsoft Visual Studio .NET task list:
Could not copy temporary files to the output directory.
-and-
The file 'bin\mywebapp.dll' cannot be copied to the run directory. The process cannot
access the file because it is being used by another process.
-and-
The file 'bin\mywebapp.pdb' cannot be copied to the run directory. The process cannot
access the file because it is being used by another process.
微软对此的解释为如下，
CAUSE
Typically, this problem occurs because of a trailing backslash at the end of the path that
is set for the root Web site. For example:
C:\Inetpub\wwwroot\
This causes the mechanism that copies the DLLs from your Bin directory to the Temporary
ASP.NET Files folder to fail. When this mechanism fails, the runtime loads the DLL
directly from the Bin directory rather then from the Temporary ASP.NET Files folder.
This problem may also occur if any virtual directories with trailing backslashes have
child directories that are marked as Web applications.

problem described in this article and should be applied only to systems experiencing this

我在看到此文前对此的解决方法是，CTRL+ALT+DEL，将进程中的ASPNET_WP.EXE去掉，
再运行，一切OK，哈哈，微软的东西真怪呀
