When I attempt to build my program I get the following:

------ Build started: Project: caller, Configuration: Demo-Release .NET ------

Performing Pre-Build Event...

Pre-Build Event failed

I have no idea how to find this error.

It my be due to that some references you have give in the code are missing or the system could not find the dependent files.

Try to give all the appropriate references.
