My HomeController looks as follows:

See below my RouteConfig:
public class RouteConfig

public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}",
defaults: new { controller = "Authentication", action = "Index" });
}
}
RouteDebugger returns TRUE for the routes {controller}/{action} and {*catchall} and confirms the AppRelativeCurrentExecutionFilePath as: ~/Home
I have debugged the code and I can successfully debug and step into the HomeController constructor and Index action method. I have also been able to step into the "~/Views/Home/Index.cshtml" however it throws the exception at the line of code:
<span class="username">#Model.UserName</span>
Funnily enough, before I step into this code I can add "#Model.UserName" to my list of watches and I can see the object and its properties fine, but for some reason it throws an exception when stepping into or over this line of code.
If the debugger steps into the HomeController, the Index action method and the Index view, then why is it all of a sudden throwing the exception it can't find the HomeController for the path "~/Home"?
The captured fiddler data can be found at the following link: http://d-h.st/IqV
I have used Razor Generator to compile my views and I am also using Ninject.Mvc to resolve my controllers. It's also worth mentioning I have cleared down and re-generated the compiled views and my project does not contain any registered areas.
Any idea's? this might be simple or an obvious one but I'm new to MVC and am reading/learning as I go.
Thanks
So people can see this question was answered here is why it was throwing the exception and how I fixed it:
The exception was being thrown because of the following line of code in the HomeController Index view:
<i class="icon-key"></i> Log Out
As you can see it's passing the wrong arguments and "Log Out" is being passed in as the action name when infact this should be "Logout". I correct it to the following and it worked:
<i class="icon-key"></i> Log Out
So if you're getting this exception and like me can't understand why then please make sure you check the rest of your code in your view to make sure it is correct. In this instance the framework doesn't provide a meaning exception message and stacktrace.
I'm new to Nancy and I'm trying to bind a decimal property using the Nancy.ModelBinding namespace like this:
var model = this.Bind<AddPaymentModel>();
My app is using a non-US culture (pt-BR) where decimals are represented differently (4.50 would be 4,50) and the code above throws an error, even thought the CurrentCulture is correctly set to pt-BR. I'm posting JSON and I think it might be related to the JSON deserializer...
Part of my stacktrace:

What am I missing?
you could try switcing to the Newtonsoft.JsonNet serializer for nancy instead.
http://nuget.org/packages/Nancy.Serialization.JsonNet
Here is a "catch all" example implementaion
using System;
using System.Collections.Generic;
using Nancy;
using Nancy.Bootstrapper;
using Nancy.Serialization.JsonNet;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
namespace Application
{
public class Bootstrapper : DefaultNancyBootstrapper
{
protected override NancyInternalConfiguration InternalConfiguration
{
get
{
return NancyInternalConfiguration.WithOverrides(
c => c.Serializers.Insert(0, typeof(ModifiedJsonNetJsonSerializer)));
}
}
public class ModifiedJsonNetJsonSerializer : JsonNetSerializer
{
public ModifiedJsonNetJsonSerializer()
: base(new List<JsonConverter> { new FloatConverter() })
{ }
public class FloatConverter : JsonConverter
{
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
var floatValue = (float)value;
writer.WriteValue(string.Format("{0:0.00}", floatValue));
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
var jobject = JToken.Load(reader);
var str = jobject.Value<string>();
float number;
try
{
number = float.Parse(str);
}
catch (FormatException)
{
str = str.IndexOf(".", StringComparison.Ordinal) > -1 ? str.Replace('.', ',') : str.Replace(',', '.');
number = float.Parse(str);
}
return number;
}
public override bool CanConvert(Type objectType)
{
return objectType == typeof(float) || objectType == typeof(Single);
}
}
}
}
}

Every type that you are trying to use as action parameter must have a default parameterless constructor. Otherwise the default model binder will not be able to instantiate it and populate its properties.
That's why you should never use your domain models in views. You should define and use view models which are classes specifically design to meet the requirements of a given view. Then the controller action will map back and forth between the view models and the domain models. Like this:
[HttpPost]
public ActionResult Index(MyViewModel model)
{
if (!ModelState.IsValid)
{
// There were validation errors => redisplay the view
return View(model);
}
// the model is valid => map the view model to a domain model and process
...
}
That's as far as best practices are concerned. If your application has already been polluted and refactoring towards view models is not possible at the moment you have two possibilities:
Write a custom model binder for the BindableEntity type so that you manually invoke the proper constructor in the CreateModel method.
Add a default parameterless constructor to the BindableEntity type.
Use the TryUpdateModel method:
[HttpPost]
public ActionResult Index()
{
var model = new BindableEntity(WHATEVER);
if (!TryUpdateModel(model) || !ModelState.IsValid)
{
// There were validation errors => redisplay the view
return View(model);
}
// the model is valid => process
...
}
I assume you have only defined constructors with parameters? To fix this, you need to add this line of code
public BindableEntity()
{ }
To your EnterpriseFramework.Entity.Synchronization.BindableEntity class.
This will define a parameter-less constructor and will allow you to use it as you desire, although you do need to define a ViewModel in order to use MVC in the way it was designed.
I have a WCF streaming binary files. Below is a shortened version of the contract.
[MessageContract()]
public class DocumentTransfer
{
[MessageHeader(MustUnderstand = true)]
public string Title { get; set; }
[MessageHeader(MustUnderstand = true)]
public string FileName { get; set; }
[MessageBodyMember(Order = 1)]
public System.IO.Stream Data;
}
Everything works fine but there are scenarios when only some other values associated with the file need to be updated but not the file itself. In that case the client sets Data = null. The Data property then cannot be interpreted/serialized and throws this exception:
System.ServiceModel.Dispatcher.StreamFormatter.Serialize(XmlDictionaryWriter writer, Object[] parameters, Object returnValue)
System.ServiceModel.Dispatcher.OperationFormatter.SerializeBodyContents(XmlDictionaryWriter writer, MessageVersion version, Object[] parameters, Object returnValue, Boolean isRequest)

System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
...UploadDocument(DocumentTransfer request)
...UploadDocument(DocumentTransfer request) in ...
Any ideas guys?
You are getting the error in SerializeBodyContents when the body is null.
You can either create a different operation for when you do not have a file, or put a byte in the stream to avoid the exception. The first of these options is preferable, the last if you cannot change the contract.
Another option would be to return Stream.Null.
