Build problem

[Zeng]

Hello,

I don't know why I'm the only one in my development team get this build
error when I build the entire solution. CommonLib.dll is a binary file
resulted of building another project included in the solution. Has anyone
had similar problem? Thanks!

The process cannot access the file because it is being used by another
process.
It appears you have an application/process accessing this file and it cannot
overwrite the file to the /Bin directory.
