I have been working on a project and I left it for about one week,when I came back to it and I tried to run the project with Ctr+F5 , it redirect to a URL which is not defined in route config. like this http://localhost:53771/Views/Home/Index.cshtml and confronted with HTTP 404: not found Error. while my route config is like this BUT IT WORKS FINE IF I TYPE THE CORRET URL MYSELF in front of the r+F5 , it redirect to a URL which is not defined in route config. like this http://localhost:53771
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default2",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
I started debugging the project and it seems the project never come to my HomeController . I just have one controller named Home, and when I removed all the codes of my Home controller it still act the same. and the other thing which it seems wrong, it creates the URL http://localhost:53771/Views/Home/Index.cshtml even before it comes to RegisterRoutes function. the problem is all local and here is my global.asax if needed. I appreciate any help

I don't believe there is any issue with your routing or your application. Visual Studio's default start action (view by right clicking project -> selecting properties -> selecting Web) is "Current Page". If you're viewing a razor view (such as your /Views/Home/Index.cshtml) at the time you run the project in visual studio, visual studio will try to navigate to this resource directly. Directly requesting a razor view is not valid in the context of an MVC application and you end up seeing the 404 error.
To avoid this, you can set the start url to a specific URL (ex: http://localhost:53771) or even simpler, open and view one of the server side files (ex: HomeController.cs) before running your project via Visual Studio.
tldr version: this is an issue with a setting you have in visual studio, not an issue with your application code
I am running into the following error with my ASP.NET MVC 3 project:
Multiple types were found that match
the controller named 'Home'. This can
happen if the route that services this
request ('Home/{action}/{id}') does
not specify namespaces to search for a
controller that matches the request.
If this is the case, register this
route by calling an overload of the
'MapRoute' method that takes a
'namespaces' parameter.
The request for 'Home' has found the
following matching controllers:
MyCompany.MyProject.WebMvc.Controllers.HomeController
MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController
I have a HomeController in my default controller folder, with a class name of MyCompany.MyProject.WebMvc.Controllers.HomeController.
My RegisterRoutes method, in my global.asax, looks like:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
I then have an area called Company, with a HomeController in the default controller folder for the area, with a class name of MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController.
The RegisterArea method in the CompanyAreaRegistration file looks like:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Company_default",
"Company/{controller}/{action}/{id}",
new { area = "Company", action = "Index", id = UrlParameter.Optional }
);
}
This is all leading the error I highlighted at the beginning of this post. I am struggling trying to piece together a solution from various other posts, with NO LUCK.
Is it possible to have a HomeController in the default controllers folder and then one in EACH area? If so, do I need to make (assuming I do) changes to my configuration file to make this work?
Any help would be much appreciated!
The error message contains the recommended solution: "If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter."
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
new string[] { "MyCompany.MyProject.WebMvc.Controllers"}
);
This will make http://server/ go to your HomeController's Index action which is, I think, what you want. http://server/company/home will go to the Company area's HomeController's Index action, as defined in the area registration.
This is the asp.net mvc4 approach:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "RegisterNow", id = UrlParameter.Optional },
namespaces: new[] { "YourCompany.Controllers" }
);
I had renamed the namespaces, so, i only delete de folders bin and obj and rebuild, work again.
If you're using RazorGenerator, just informing the namespaces parameter could be not enough.
I got to solve adding the statement marked below at Global.asax.cs:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
ControllerBuilder.Current.DefaultNamespaces.Add("MyProject.Controllers"); // This one
}
Another plausible cause of this issue could be found below:
Multiple types were found that match the controller named 'Home'
use this
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new[] { "ProjectName.Controllers" }
);
Use only the name of the project:
Public Class RouteConfig
Public Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
routes.MapRoute( _
name:="Default", _
url:="{controller}/{action}/{id}", _
defaults:=New With {.controller = "Home", .action = "Index", .id = UrlParameter.Optional} _
, namespaces:={"MvcAreas"})
End Sub
I had the same issue and found that the older version had created compiled files in the "bin" folder.
Once I deleted these the error disappeared.
As Chris Moschini mention the namespaces parameter may not be enough if you have two areas with same controller name with different namespaces and the default none area route will return 500 server error.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
new string[] { "MyCompany.MyProject.WebMvc.Controllers"}
);
It "best" to override the default route handler and add this line:
RequestContext.RouteData.DataTokens["UseNamespaceFallback"] = false;
I had this issue after I added a reference to another project that had the same routes and the problem continued after I removed the reference.
Resolved by deleting the .dll file of that added reference from the bin folder and rebuilding.
Like many others, I had this problem after creating a new MVC template project from VS2017 menu, on building the project I would get the op's error message. I then used the answer https://stackoverflow.com/a/15651619/2417292 posted earlier in this thread by cooloverride
for mvc4 projects.
This still didn't fix my issue so I renamed my Home view folder and HomeController file to be the view folder Company/ and controller file CompanyController. This then worked for me, not a fix per say but a workaround if your not stuck on having the route Home/Index my other issue was I couldn't find the reference causing the error and due to my dev platform being Azure WebApplication vs a full VM with a complete file system and IIS settings to mess with.
For MVC5 below code works for issue same controller name for different areas. You have to specify which area controller have to hit first.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new[] { "ApplicationName.Areas.AreaName.Controllers" }
).DataTokens.Add("area", "AreaName");
This issue occurred when I accidentally added
[Route("api/[controllers]s")]
instead of
[RoutePrefix("api/[controllers]s")]
to the top of my ApiController.
I've been working on a Web site with ASP.NET MVC version 1, deployed in a Windows Server 2008 R2 (IIS7, integrated mode). The site works well in intranet enviroment, but recently was published in Internet with a public domain name. RedirectToAction still aims to private IP, causing redirect to login page. Where I can specify the change?
For notAnExpert petition, an extract of my code. Nothing special here, only the default conventions:
return RedirectToAction(string.Format("Details/{0}", CampaignId), "Campaigns");
In my Global.asax neither:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute("clicked_links", "Clicked/Index", new { controller="Clicked", action="Index"});
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
My fault guys, in the view I find this
<form action=<% Request.URL %>
Additionaly the web server was misconfigured.
I'm still new to ASP.NET MVC and I'm struggling a little with the routing.
Using the ASP.NET development server (running directly from Visual Studio), my application can find its views without any problems. The standard ASP.NET URL is used - http://localhost:1871/InterestingLink/Register
However, when I publish my site to IIS and access it via http://localhost/MyFancyApplication/InterestingLink/Register, I get a 404 error.
Any suggestions on what might be wrong?
More info...
This is what my global.asax file looks like (standard):
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
}
My controller is also very simple:
public class InterestingLinkController : Controller
{
public ActionResult Register()
{
return View("Register");
}
}
I figured out what was wrong. The problem was actually that IIS5 (in Windows XP) does not fire up ASP.NET when the URL does not contain a .ASPX. The easiest way to get around this is to add a '.aspx' to your controller section in global.asax. For example:
routes.MapRoute(
"Default",
"{controller}.aspx/{action}/{id}",
new { controller = "Home", action = "Index", id = "" }
);
Not pretty, but it will do.
Lots of things could be wrong:
Is the IIS Virtual Directory & Application set correctly?
Is the ASP.NET application being called at all? (Add some logging/breakpoiont in Application_Start and Application_BeginRequest)
Just for a start. You are going to have to apply the usual debugging approaches.
(To avoid issues like this, I rarely use the development server and just use IIS the whole time: most difficult thing is remembering to run VS elevated every time.)
I am having problems with thinking up a solution for the following. I got a blog which I recently upgraded from web forms to MVC. The blog is avalible in both swedish and english on two different domains and are running in the same web site in IIS.
The problem is that I would like language specific urls on the both sites, like this:
English: http://codeodyssey.com/archive/2009/1/15/code-odyssey-the-next-chapter
Swedish: http://codeodyssey.se/arkiv/2009/1/15/code-odyssey-nasta-kapitel
At the moment I have made this to work by registering the RouteTable on each request depending on which domain is called. My Global.asax Looks something like this (not the whole code):
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
string archiveRoute = "archive";
if (Thread.CurrentThread.CurrentUICulture.ToString() == "sv-SE")
{
archiveRoute = "arkiv";
}
routes.MapRoute(
"BlogPost",
archiveRoute+"/{year}/{month}/{day}/{slug}",
new { controller = "Blog", action = "ArchiveBySlug" }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
routes.MapRoute(
"404-PageNotFound",
"{*url}",
new { controller = "Error", action = "ResourceNotFound" }
);
}
void Application_BeginRequest(object sender, EventArgs e)
{
//Check whcih domian the request is made for, and store the Culture
string currentCulture = HttpContext.Current.Request.Url.ToString().IndexOf("codeodyssey.se") != -1 ? "sv-SE" : "en-GB";
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(currentCulture);
Thread.CurrentThread.CurrentUICulture = new CultureInfo(currentCulture);
RouteTable.Routes.Clear();
RegisterRoutes(RouteTable.Routes);
Bootstrapper.ConfigureStructureMap();
ControllerBuilder.Current.SetControllerFactory(
new CodeOdyssey.Web.Controllers.StructureMapControllerFactory()
);
}
protected void Application_Start()
{
}
This works at the moment but I know it not a great solution. I have been getting a "Item has already been added. Key in dictionary" error when stating up this app and it does not seems stable at times.
I would like to only set up my routes in the Application_Start as they should and not having to clear them on every request like I am doing now. Problem is that the request object does not exist and I have no way of knowing which of the language specific routes I should register.
Been reading about the AppDomain but could not find many examples on how to use it on a web site. I'we been thinking to star something like this:
protected void Application_Start()
{
AppDomain.CreateDomain("codeodyssey.se");
AppDomain.CreateDomain("codeodyssey.com");
}
Then registring each web sites routes in each app domain and send the requests to one of them based on the url. Can't find any examples on how to work with AppDomains in this manner.
Am I completely off track? Or is there a better solution for this?
The ASP.Net runtime manages AppDomains for you, so its probably not a good idea to create AppDomains in your code.
However, if you can, I would suggest creating multiple IIS Applications (one for http://codeodyssey.com and one for http://codeodyssey.se). Point both applications at the same directory on disk. This will give you the two AppDomains you are looking for.
Then, in your Application_Start code, you can check the domain and build routes accordingly.
