I'm trying to upload package to GalleryServer I set up. As a test case, I pulled "elmah" package to local VS and used elmah.1.1.nupkg to submit to new empty gallery. Getting this error about IPackageFactory, tried it both on local and remote servers with same result. Am I doing something wrong?

The server encountered an error processing the request. Please see the service help page for constructing valid requests to the service. The exception message is 'Could not find a type implementing 'IPackageFactory' in assemblies in the directory 'D:\Projects\hg\galleryserver\GalleryServer\src\Gallery.Server\bin'.'. See server logs for more details. The exception stack trace is:

Moving nuget dlls from the plugins directory fixed this issue. Getting closer - now it is bombing in the PackageAuthenticator.Verify method. I can see temp file created, but verification is failing and turning authenticate request off in config doesn't seem to help. Will try to debug tomorrow.
