In the inventor API most lists do not implement IEnumerable(Of ....). Therefore linq won't work on lists straight from the API. But you can almost always cast to an IEnumerable(Of ....). Here some example:

Dim docs As IEnumerable(Of Document) = ThisApplication.Documents.Cast(Of Document)

Dim fileNames = docs.Where(Function(d) d.FullFileName.Contains(".ipt")).
					Select(Function(d) d.FullFileName)

or if you prefer in C#

IEnumerable<Document> docs = ThisApplication.Documents.Cast<Document>();

var fileNames = docs.Where(d => d.FullFileName.Contains(".ipt")).
                    Select(d => d.FullFileName);

Here you have some examples

Dim oDrawDoc as DrawingDocument = thisapplication.activedocument
Dim oSheet as Sheet = oDrawDoc.Sheets.Cast(Of Sheet).Where(Function(s) s.Name.Contains("MasterDrawing")).FirstOrDefault()

	Dim oDrawingViews As DrawingViews = oSheet.DrawingViews
	Dim oExtView As DrawingView = oDrawingViews.Cast(Of DrawingView).Where(Function(s) s.Name = "EXT.").FirstOrDefault()
