There should be a simple Linq query for what I'm trying to accomplish, but I'm producing some ugly code.

I have two tables, one of issues and another of issue status. There is a one-to-many relationship between issue and issue status. When an issue is created an IssueStatus is also created with the status field set to "Open" when it is closed, another IssueStatus is created with the status field set to "Closed" ... but issues can be re-opened. It seems like I should be able to write something like this:

    public static List<Issue> FindOpenIssues(this IList<Issue> issues) {
        return (
            from issue in issues
            from issueStatus in issue.issueStatus.OrderBy(x=>x.CreatedOn).Single() 
            where issueStatus.Status == "Open"
            select issue
            ).ToList();
    }

This obviously fails, but there must be a clean way to do this? Thanks!
