Hello all,

Firstly, the topic is related to WebAPI but i didn`t see any category with WebAPI. So posted under Web services.

I`m working on a WebAPI application (ASP.NET MVC, Entity Framework) & trying to DELETE an entry from Database. Below is the code related to DELETE verb.

public HttpResponseMessage Delete (int empId)
{
try
{
using (WebApiTrialEntities entity = new WebApiTrialEntities())
{
var isAvailable = entity.Employees.FirstOrDefault(e => e.ID == empId);
if (isAvailable !=null)
{
entity.Employees.Remove(isAvailable);
entity.SaveChangesAsync();
return Request.CreateResponse(HttpStatusCode.Gone, "EmpId " + empId + " is Deleted");
}
else
{
return Request.CreateErrorResponse(HttpStatusCode.NotFound, "EmpId " + empId + " is NotFound");
}
}
}
catch (Exception ex)
{
return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ex);
}
}

Using Fiddler - we see Header value as '405 Method Not Allowed' with message as "The requested resource does not support http method 'DELETE'.

Please help me out & suggest me to correct my mistakes.

Thanks in advance.

If you are calling your service from client please check with http verb ,verb should be a DELETE only.

Hi L A,

I think you are using IIS 7.0 or later version. This issue is related to WebDAV extension module . This will come while Post or delete request. Please try below setting in web config

disable Webdav in and within your confir file

OR can do directly in IIS setting

I think it automatically redirect to the same address with this new parameter AspxAutoDetectCookieSupport=1

Please add this in your web config and try

Hello Midhun T P, thanks for your reply.
I have already made these configuration settings in Web.config but it didn't work.
