Investigate useage of Dictionary<'k, 'v>.Add('k, 'v) instead of indexer.

[baronfel]

Description

I believe that there's a dictionary Add exception leaking out of the provider that could be easily worked around by changing usages of .Add(key, value) to use the indexer : [key] <- value.
Per MSDN, the indexer never throws.

Repro steps

run the provider pointed at the json config in this gist

Expected behavior

It would be great if the duplicate key was either avoided using the indexer, or the key that caused the error was reported.

Actual behavior

you get this error:

Known workarounds

None at the moment, investigating to see if there's an error in my schema.
