I'm pretty new to .net also, so I suppose flex data services would be about the same learning curve.
FDS, would it have any advantages over taking a .net approach? I seem to recall that FDS/LCDS has two way update notification/synching services or something of that order, which I took to mean that the flex ui would be updated passively if changes are made to the viewed data by another user? Would that be hard to emulate in .net, or would fluorine or WebOrb be able to help with that? Fluorine would connect flex and the .net side. But I'm not clear what the .net methods that you describe are exactly? Would they be a set of classes that call sprocs in the sql server db, either built manually or as generated by an ORM? I'm not clear on the limitations of the free version of LCDS, and what it costs if you need to go beyond the limitations of the free version? Samuel R.
