在Asp.net Mvc 5中的HttpPut？

Question

I was trying to use "PUT" in my controller like

public class HomeController : Controller
    {
        [HttpPut]
        public ContentResult Test()
        {
            return Content("hi");
        }
    }

but I can't access it. I thought it was my code but after trying fiddler and getting the same error(404).

I think something else is up. I am just using iis express and mvc 5.

Before I never used HttpPut but been doing webapi lately so that's why I tried to do it in mvc 5 controller but I am not sure if in this case it bring me anything(especially with extra setup is needed as it seems like it is need)

Post request works

Another possibility is to update the ExtensionlessUrlHandler-Integrated-4.0.

<system.webServer>
    <handlers>
        <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
        <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*"   type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
</system.webServer>

There are several possibilities for this failure. One is security, meaning that PUT header is being blocked:

Does your web server allow PUT headers? Try this:

...    
 <security>
            <requestFiltering>
                <verbs>
                    <add verb="PUT" allowed="true" />
                </verbs>
            </requestFiltering>
        </security>
    </system.webServer>

The other possibility is that your test is being subject to CORS (Cross Origin Resource Sharing) and you may need to enable it in MVC. I have personally not done this MVC but only WebApi. I hope this link can help you:
