    Does not work in 6.1.x

    I believe the class ConfigTree needs the TreeAttribute added.

    Without it the packages causes System.InvalidOperationException: Sequence contains no elements while installing this package as well as some others.  I was unable to install courier correctly because this error stops the install somewhere along the lines.

    Here is the code in the umbraco core that fails:


    public ApplicationTreeRegistrar()

            { ....

    var items = types.Select(x => new Tuple<Type, TreeAttribute>(x, x.GetCustomAttributes<TreeAttribute>(false).Single())).Where(x => ApplicationTree.getByAlias(x.Item2.Alias) == null);

    .. }

    The .Single fails because it is missing.

    Would love to have this working on 6.X.X as well.

    I think there is a builtin ver in 6.1.6.

    I can confirm that. 
    In Developer, click the root node and there should be a tab in the dashboard called "Examine Management"
