I am trying to figure out how I get dropzone.js to work with a C# based web service. But the issue I got is that I am running into a 404 error after I selected a file to upload. These are the steps I have done: In VS2012 I started an empty MVC4 application. Then I added and index.html, dropzone.js and jquery via NuGet (don't know if dropzone needs it, just added it to be save). Based on the example on the website of dropzone.js, I wrote the next html code: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link href="CSS/FileUploader.css" rel="stylesheet" /> <script src="Scripts/jquery-2.0.2.min.js"></script> <script src="Scripts/DropZone.js"></script> <script> </script> <title>File Uploader test</title> </head> <body> <form action="/FileUpload/FileUploadController" class="dropzone" <!-- this css class contains: background-color: yellow; --> id="my-awesome-dropzone"></form> </body> </html> I added a routing to the routing config in the RouteConfig.cs like this: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute( name: "FileUpload", url: "FileUpload/FileUploadController", defaults: new { controller = "FileUploadController", action = "FileUpload" } ); } And my controller looks like this: public class FileUploadController : Controller { [HttpPost] public ActionResult FileUpload(IEnumerable<HttpPostedFileBase> files) { return null; //Breakpoint here } } I put a breakpoint on the "return null" line just to test if the method is called properly. When I run the code and open the html page, the dropzone control works properly. But when I select a file, this error is shown: The HTTP verb POST used to access path '/FileUploadController/FileUpload' is not allowed. and I cannot figure out why. Also, the code doesnt break on the break point so I guess the method isn't called properly. What am I doing wrong here?
