Using LINQPad I've added a private feed to Visual Studio Team Services. However one of my packages requires a pre-release package: Quartz.Net in my case. I've ticked Include Prerelease but I think it's getting confused and trying to load the package from my private feed rather than NuGet.
I've tried to work around the issue by loading the package into the local package cache. LINQPad doesn't seem to consider this. Other than uploading these packages into my own private feed, what options do I have? I'm not going to alter my own packages to get around LINQPad's shortcomings.
Note: I've setup the VSTS feed according this question.
Here is what my NuGet feeds look like in LINQPad
