VSO using Nuget packager build agent fails with invalid properites

Question

I'm using VSO to package a simple DLL and the publish it to an internal feed, unfortunately during the packaging stage build it reports success but I get no artifact to publish

In the log file on for the publish it states the packing includes invalid arguments (Log 2016-02-27T09:07:35.8808468Z) as a result the publisher can't file any .nupkg file to publish.

I'm not sure where I'm going wrong. Its as if the nuget.exe is the wrong version or do it need to include anything in my solution this is just a basic .enter image description herecsproj library with one static function for testing the process.

Answer 1

Unfortunately I copied the Configuration=${BuildConfiguration} parameter incorrectly (use {} instead of ()), I also had to make other changes , I didn't require the platform parameter. I was also packaging to the incorrect folder.
