I forked this and updated to work with xUnit 2.1.0 and the new nuget package for xunit.runner.msbuild. I also made a couple tweaks to the targets, opting to keep both the nunit and xunit xml files, and also to delete them even for normal builds. With the nuget changes, it was no longer necessary to validate the existence of NuGet.targets.

This works for me on Bamboo, otherwise following the instructions of the author from http://www.northcloud.com/integrating-xunit-net-into-bamboo-build-plans-with-msbuild/. Thanks @coldacid.
