ASP.NET Web API datetime binding

Question

I submit JSON object, with date value "02/11/2015" (DD/MM/YYYY) to API controller. For some reason it gets converted into US format while binding (11th of Feb). I have standard MVC controllers in the same solution, which bind date value submitted in the same format correctly (UK). What would be causing this difference:

Here are standard MVC submission headers:

Accept:*/*
Accept-Encoding:gzip, deflate
Accept-Language:en-US,en;q=0.8,pl;q=0.6
Cache-Control:no-cache
Connection:keep-alive
X-Requested-With:XMLHttpRequest

And Form Data

StartDate : 01/11/2015

Here Are API call headers

Accept:application/json, text/javascript, */*; q=0.01
Accept-Encoding:gzip, deflate, sdch
Accept-Language:en-US,en;q=0.8,pl;q=0.6
Cache-Control:no-cache
Connection:keep-alive
Content-Type:application/json; charset=UTF-8
X-Requested-With:XMLHttpRequest

And JSON object that I pass

{ DateStart: "01/11/2015" }

I guess the default dateFormat in webapi json serializer is not the same as MVC's one.

Try to specify in your WebApi in the config file (App_start/WebApiConfig).

Example:

var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
json.SerializerSettings.DateFormatHandling = Newtonsoft.Json.DateFormatHandling.MicrosoftDateFormat;

Or GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.DateFormatString = "yyyy-MM-dd"

with the DateFormat, DateZone you need.

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.DateFormatString = "yyyy-MM-dd" in the register method of your webapiconfig file does not change the format?

Made it work finally using custom converter for DateTime type: config.Formatters.JsonFormatter.SerializerSettings.Converters.Insert(0, new MyDateTimeConverter()); Thanks for your help
