After running through some
Pluralsight training in relation to WebApi development my colleagues and I
discovered whilst trying to follow the tutorial that Delete and Update methods
(PUT and DELETE verbs) implemented within the controller classes would not seem
to work. A little bit of head scratching, double checking and digging later
revealed that the issue was due to a configuration issue with IIS8. It seems
that out of the box IIS8 ships with the verbs PUT and DELETE disabled. The
issue was resolved very simply by:-
1. Opening the IIS8
ApplicationHost.Config file located within the directory
‘%userprofile%\documents\iisexpress\config”
2. Change the “Verb” values from the
following line
<add
name="ExtensionlessUrl-Integrated-4.0" path="*."
verb="GET,HEAD,POST,DEBUG"
type="System.Web.Handlers.TransferRequestHandler"
preCondition="integratedMode,runtimeVersionv4.0" />
to read
<add
name="ExtensionlessUrl-Integrated-4.0" path="*."
verb="GET,HEAD,POST,DEBUG,PUT,DELETE"
type="System.Web.Handlers.TransferRequestHandler"
preCondition="integratedMode,runtimeVersionv4.0" />
Note the inclusion of the PUT and
DELETE verbs.
3. Now recompile and run your code,
which should restart your web server and hey presto your Delete and Update
methods should work as intended.
