    {
        protected void Application_Start()
        {
            RouteConfig.RegisterRoutes(RouteTable.Routes);
        }
    }


public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }
    }

public class TestController : ApiController
    {
        public string Get()
        {
            return "Hello world!";
        }
    }

Answer 1

Hi,

Can you make sure the MVC assemblies has been set copy to local property with "True" in MVC 4 website application? And i'd like to suggest you set debug to ture to collect more information about the exception. The configuration will be like this:

<compilation debug="true"/> 

In addition, Do you enable .NET 4.5 or .NET 4.0 for MVC web application? Would you like to check the target frameworks version with web config file?

Hope this helps.

Answer 3

Hi,

Cant you got more details about that exception? (include event logs, stack, trace, etc), 500 error maybe a very broad error message. You can set customErrors mode="On" .

i note there's Microsoft.Practices.EnterpriseLibrary assembly in your list,  please let me know the version of the Enterprise Library you're using. The lastest version is here:

http://www.microsoft.com/en-ca/download/details.aspx?id=6836 

Hope this helps.

Answer 4

Thanks, Arwind.

There's no more detailed exception information, because server http response has head but no body.

Microsoft.Practices.EnterpriseLibrary should be the latest version,is 5.0.505.0.

Answer 7

Hi,

Yes, As I was mentioned above, 500 error maybe a very broad error message, we can not make sure where the exception was thrown, so i think you need post them first. The configurations and code looks no propblem.

BR,

Arwind

Answer 8

Yes, As metioned by Arwing and me, to trace what problem is exactly causing 500 error, you can enable intelli trace. The link in my previous post helps you to understand how to achieve it.

Answer 9

Hi Arwind,

I know the 500 error is a very broad error message, but the response from the server does only this, there is no more detailed exception, because the http response is the only head, but not the body!

Hi Veerendra Kumar,

I find on the Internet, intelli trace is not used in the windows azure web site (not a cloud service), if you know how to turn on, please tell me, thank you.



I solved my problem, by re-create my Asp.Net mvc web api project, the cause of the problem may be because my project is upgrade from Asp.Net mvc 4 beta.
