    # BSON Type Provider
  
    This article demonstrates how to use the BSON type provider to access
    `.bson` files in a statically typed way.
  
    The BSON type provider provides statically typed access to `BsonDocument`s.
    It takes as input a sequence of sample documents (e.g. the output from the
    `mongodump` utility). 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 samples, then a runtime error may occur (e.g. when accessing a
    nonexistent field).
  
    ## Introducing the provider
  
    The type provider is located in the `FSharp.Data.Bson.dll` assembly.
    Assuming the assembly is located in the `../../../bin` directory, we can
    load it in F# Interactive as follows:

  ## Summary
  
  This article demonstrated the `BsonProvider` type. The provider infers
  the structure of a `.bson` file and exposes it to F# programmers in a
  nicely typed way.
