Unable to restore nuget packages when first nuget feed doesn't have the package

wangzq

I have added a local nuget feed as first one, now when opening a query which is using a package (latest version) from second (official) nuget feed, it will fail to restore the nuget package, which I believe is due to following code (decompiled from latest beta versio) from NuGet3Agent.Download:

	if (version == null)
	{
		ProjectContextLogger logger = new ProjectContextLogger(projectContext);
		ResolutionContext getLatestContext = new ResolutionContext(1, root.MainPackageRef.AllowPrelease, false, 0);
		ResolvedPackage obj = await TaskExtensions.CAF<ResolvedPackage>(Task.Run(() => NuGetPackageManager.GetLatestVersionAsync(root.MainPackageRef.ID, folderNuGetProject, getLatestContext, sourceRepos.First(), logger, cancelToken)));
		version = ((obj != null) ? obj.get_LatestVersion() : null);
		if (version == null)
		{
			throw new Exception("Unable to find package '" + root.MainPackageRef.ID + "'.");
		}
	}

Since we are always using the first feed (sourceRepos.First()) this explains why changing the order of the feeds would workaround this issue. Can we check all feeds for latest version?

Thanks

I think you'd better switch the nuget feed order, check all feeds would causing performance issue and not make a good sense here.
