  +When the sample is a collection, the type provider generates a type that can be used to store
   all values in the sample. In this case, the resulting type is `decimal`, because one
   of the values is not an integer. In general, the provider supports (and prefers them 
   in this order): `int`, `int64`, `decimal` and `float`.

  ### Inferring type from sample
  
  The `JsonProvider<...>` takes one static parameter of type `string`. The parameter can 
  be _either_ a sample string _or_ a sample file (relatively to the current folder or online

  This article demonstrates how to use the JSON type provider to access JSON files
  in a statically typed way. We first look how the structure is inferred and then 
  demonstrate the provider by parsing data from WorldBank and Twitter.
  
  The JSON type provider provides a statically typed access to JSON documents.
  It takes a sample document as an input (or a document containing a JSON array of samples).
  The generated type can then be used to read files with the same structure. If the 
  loaded file does not match the structure of the sample, an runtime error may occur 
  (but only when accessing e.g. non-existing element).
