Cannot create/shadow copy <your assembly file> when that file already exists

Cannot create/shadow copy < your assembly file dll > when that file already exists

When you compile the web projects in visual studio 2005/2008, you may receive the above message. 
And in order to get rid of this, you can either kill the process aspnet_wp.exe using the task manager 
or add the following tag in the web.config inside system.web tag.

<hostingEnvironment shadowCopyBinAssemblies="false" />

Although the former resolution is just a temperory fix, the later one will fix this issue for that 
project permanantly.
