Download Build binaries from Visual Studio Team Services
According to the logs, the build result files has been uploaded. You can click "Artifacts" link to download these files:
Have you added a Publish Build Artifacts or Copy and Publish Build Artifacts task at the end of your build? Only if you publish the items you want to keep at the end, are the outputs of the builds kept.
Since your Copy action includes the
$(buildconfiguration) variable in the source folder mask, make sure that the Visual Studio Build task uses this same variable.
