Visual Studio locks output file on build

I had this problem and resolved it with some custom code. See here: Visual Studio 2010 build file lock issues

Compile the utility in the accepted answer and reference it during the build step as described to workaround the problem. I still turn off VS 2010 at lunch to clean up the morning's work.

The reason for the custom code was that the often recommended solution only worked once and then the renamed files were also locked, preventing the rename. Here we just append the data-time info to the file so the renamed versions can't conflict.
