You should rename all references/using statements from umbraco.NodeFactory to umbraco.presentation.nodeFactory

Thanks kipusoep but now i get context errors with ConfigurationManager and HttpContext.
Any idea?

What is/are the exact message(s)?

Using umbraco.NodeFactory:

Error    1    The type or namespace name 'NodeFactory' does not exist in the namespace 'umbraco' (are you missing an assembly reference?)    C:\Documents and Settings\buddychrist\Mis documentos\Visual Studio 2010\Projects\InfoCaster.Umbraco.DateFolders\InfoCaster.Umbraco.DateFolders\DateFolders-1.3.cs    39    15    InfoCaster.Umbraco.DateFolders

Using umbraco.presentation.nodeFactory instead:

            _itemDocType = ConfigurationManager.AppSettings["itemDocType"].Split(',');
            _itemDateProperty = ConfigurationManager.AppSettings["itemDateProperty"];
            _dateFolderDocType = ConfigurationManager.AppSettings["dateFolderDocType"];

Error    2    The name 'ConfigurationManager' does not exist in the current context    C:\Documents and Settings\buddychrist\Mis documentos\Visual Studio 2010\Projects\InfoCaster.Umbraco.DateFolders\InfoCaster.Umbraco.DateFolders\DateFolders-1.3.cs    59    28    InfoCaster.Umbraco.DateFolders

Several HttpContext errors:

                    HttpContext.Current.Items.Add("monthId", doc.ParentId);
                    HttpContext.Current.Items.Add("yearId", doc.Parent.ParentId);

Error    5    The name 'HttpContext' does not exist in the current context    C:\Documents and Settings\buddychrist\Mis documentos\Visual Studio 2010\Projects\InfoCaster.Umbraco.DateFolders\InfoCaster.Umbraco.DateFolders\DateFolders-1.3.cs    78    21    InfoCaster.Umbraco.DateFolders

You can just click on ConfigurationManager and HttpContext (so the cursor is somewhere inside that term) and press CTRL + . (dot). A context menu will appear and gives you the ability to automatically add a using statement.

If it doesn't appear or gives other options than described above, you're references are wrong;
1. You're not referencing the needed .NET assemblies
2. You're referencing multiple .NET versions thorugh the assemblies 

Thanks!

I will give check it carefully and try again starting a new project.

No problem... Did you seriously mark your own post as the answer while I gave you the answer?

Looks greedy to me...

Sorry kipusoep, i didnt mean to be ungrateful. If I mark my final post as the answer was only for including .dll referenced files and describe the complete solution in my case.

I am really gratefull for your help and quick response and so i give you a High five.

Best regards,
Ivan

Normally you'd mark the one post, which helped you best to solve your problem, as 'the answer'.
That way people receive karma for helping others, which stimulates the our umbraco ecosystem.

So please, in the future be gentle and mark answers like you should ;-)

No problem and good luck!
