Sending large json data to breezecontroller fail

Question

I'm using breezejs to handle my entities on a web application.

Specifically i start with the Angular HotTowel template.

The problem i'm having is that i'm sending a large json array of objects (length about 17000) so on my controller im getting null on the parameter to receive this information.

When I try to send less data an array of 5000 objects then the controller parameter is setted with the objects correctlly.

My controller

[BreezeController]
public class SoftProductsController : ApiController
{
    private readonly EFContextProvider<Context> contextProvider = new EFContextProvider<Context>();

    [HttpGet]
    public string Metadata()
    {
        return this.contextProvider.Metadata();
    }

    [HttpPost]
    public SaveResult SaveChanges(JObject saveBundle)
    {
        //Here saveBundle is NULL
        return this.contextProvider.SaveChanges(saveBundle);

    }
}

Could be this related to some json deserialization on WebApi when using large json data?

I tried setting this option on the web.congif with no success

<appSettings>
    <add key="aspnet:MaxJsonDeserializerMembers" value="20000"/>
</appSettings>

I'm using .NET 4.5

Any idea?

My problem was the default limit on requestLenght that ASP.NET have. Increasing that limit on the web.config allow breeze to post large data. (default size is 4096 KB)

<system.web>
    <httpRuntime targetFramework="4.5" maxRequestLength="5120" />
</system.web>
