JSON to C# POCO - don't use dynamic types

Hi all,

Wow there are about a million questions and answers regarding this on stack overflow, "How do you convert JSON to a C# Object?".  There are a ton of different ways to do it.  One SO Q/A I looked at was this:

http://stackoverflow.com/questions/2246694/how-to-convert-json-object-to-custom-c-sharp-object

One of the answers suggests using a dynamic type, which sounds awesome.  Using a simple one liner, you can parse the JSON into an object.

dynamic user = Json.Decode(json);

Then you can do this.

var name = user.name;

GREAT!  But the problem is, the name field is not type checked at compile time.  For example, this will also compile.

var name = user.naem;  // Compiles but generates a run-time error!

This leads me to the conclusion that dynamic types are really no better than a dictionary.  For example, you could convert the JSON to a dictionary and have the same problem:

var name = user["name"]; // Compiles and runs!

var name = user["naem"]; // Compiles and has a run-time error.

I am going to NOT use dynamic types as much as possible.
