Validate Input Json agains schema

Hi,
I’m using NewtonSoft library to validate input json data, in my rest routes before going futher down the code, so i dont have to bother with validation.
So i create a JSon schema, and when the data are sent to one of my route, i make sure the input json is valid. If not, i exit the route and return an array of the errors present in the input JSON.

Maybe this could be a good idea to implement this idea natively when a route has a POST/PUT/DELETE method, we could imagine a parameter -JsonSchema pointing to a valid schema file …

This is how i do it:
Before starting UD i import the DLL and create a custom class

$NewtonsoftJsonPath = "c:\Common\NewtonSoft\Newtonsoft.Json.dll"
$NewtonsoftJsonSchemaPath = "c:\Common\NewtonSoft\Newtonsoft.Json.Schema.dll"

Add-Type -Path $NewtonsoftJsonPath
Add-Type -Path $NewtonsoftJsonSchemaPath

$source= @"
    public class Jsonvalidation
    {
        public static System.Collections.Generic.IList<string> IsValid (string jsonFile, string schemaFile)
        {
            var schema = System.IO.File.ReadAllText(schemaFile);
            var jToken = Newtonsoft.Json.Linq.JToken.Parse(jsonFile);
            var jSchema = Newtonsoft.Json.Schema.JSchema.Parse(schema);
            System.Collections.Generic.IList<string> messages;
            Newtonsoft.Json.Schema.SchemaExtensions.IsValid(jToken, jSchema, out messages);
            return messages;
        }
    }
"@

And you can call it like that [JsonValidation]::isValid($body,"pathtomyschema")
If there are errors, an array of error is returned, and i output it, then exit my route.
