library file

[Patty]

When I build asp.net solution, sometimes I found the
library file(one of the project dll) could not
overwritten, any one know what's the problem is?

Thanks in advance!

the most common cause is that the dll is being used. I sometimes have this
happen if I run the app without debugging; the dll in your project's bin
folder is being used, so VS.NET will not overwrite it if you build while an
instance of the app is running.

or if another process is holding onto it as well....
