Hi Friends,
I am Exploring WebApi now a days . Today i confronted an error "The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used" whenever i execute a delete operation .
GET,POST operations were executing smoothly though i was only getting an error for DELETE operation in WebApi.
After struggling for an hour i found a solution for this .
Solution: We require to add a entry point for VERB "DELETE" into the applicationHost configuration file. exist at %userprofile%\documents\IISExpress\config folder.
Open the given file and find a value "ExtensionlessUrl-Integrated-4.0" , Now add PUT and DELETE into "verb" parameter as i have added and marked highlighted in yellow.
<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,DELETE,PUT" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" responseBufferLimit="0" />
WebApi has started working anticipated.
Enjoy WebApi benefits.
