Project dll error in Visual Studio 2013 output upon Build - visual-studio-2013

Question

When I build my project, I get this message in the Output window:
1>------ Build started: Project: ProjectX, Configuration: Debug Any CPU ------
1> ProjectX -> C:\Users\Alfred\Documents\Visual Studio 2013\Projects\ProjectX2015\ProjectX\ProjectX\bin\ProjectX.dll
========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
I think it started after an update-package. It compiles but I'm starting to wonder what the 2nd line mean:
1> ProjectX -> C:\Users\Alfred\Documents\Visual Studio 2013\Projects\ProjectX2015\ProjectX\ProjectX\bin\ProjectX.dll
Is this a real error or just something to ignore?
Below is my ProjectX.dll.config (sanitized):

Answer 1

The first line of the output indicates that a build for a project (named "ProjectX", with "Debug Any CPU" configuration) is started. On the second line, it then outputs the location of the resulting binary. Finally, on the third line, it shows build results for all projects in the current solution.
This is standard output for a successful build of one project. Depending on the complexity of the project, there will sometimes be more lines, but lines 1 and 3 will always be there. The line 2 that shows the location of the output file will only be present in case of a successful build.
