Hi all,

I am modifying my existing application that is already in production to include enhancements. But I'm getting this compile error:

Code:
Preparing resources...
Updating references...
Performing main compilation...
Building satellite assemblies...
The file 'vendor.exe' cannot be copied to the run directory.  The requested operation cannot be performed on a file with a user-mapped section open.
Could not copy temporary files to the output directory.
What does this mean? I tried rebooting my PC but to no avail.

Pls help.
