type JsonProvider

Full name: FSharp.Data.JsonProvider


<summary>Typed representation of a JSON document.</summary>
       <param name='Sample'>Location of a JSON sample file or a string containing a sample JSON document.</param>
       <param name='SampleIsList'>If true, sample should be a list of individual samples for the inference.</param>
       <param name='RootName'>The name to be used to the root type. Defaults to `Root`.</param>
       <param name='Culture'>The culture used for parsing numbers and dates. Defaults to the invariant culture.</param>
       <param name='Encoding'>The encoding used to read the sample. You can specify either the character set name or the codepage number. Defaults to UTF8 for files, and to ISO-8859-1 the for HTTP requests, unless `charset` is specified in the `Content-Type` response header.</param>
       <param name='ResolutionFolder'>A directory that is used when resolving relative file references (at design time and in hosted execution).</param>
       <param name='EmbeddedResource'>When specified, the type provider first attempts to load the sample from the specified resource
          (e.g. 'MyCompany.MyAssembly, resource_name.json'). This is useful when exposing types generated by the type provider.</param>
       <param name='InferTypesFromValues'>If true, turns on additional type inference from values.
          (e.g. type inference infers string values such as "123" as ints and values constrained to 0 and 1 as booleans.)</param>
