ASP NET Web API - PUT DELETE Verbs Not Allowed - IIS 8

Question

I recently upgraded from Visual Studio 2010 to the Visual Studio 2012 RC  The installer also installs IIS 8 Express which Visual Studio now uses as the default web server   IIS 8 is blocking my WEB API requests that use PUT AND DELETE verbs  IIS returns a 405 error  The requested resource does not support http method  PUT    I know people have issues with this in the past and there are several messages about it on Stack Overflow  With IIS 7 Express the solution was to uninstall WebDav  Unfortunately I don t see any way to do that with IIS 8    I ve tried editing out the WebDav sections from applicationhost config but that hasn t helped  For example I removed  lt add name  WebDAVModule  image   IIS BIN  webdav dll    gt  from the config file   I ve spent far too long on this  There must be a simple way to enable PUT and DELETE

Okay  I finally got to the bottom of this  You need to jump through some hoops to get the PUT and DELETE verbs working correctly with IIS8  In fact if you install the release candidate of VS 2012 and create a new WEB API project you ll find that the sample PUT and DELETE methods return 404 errors out of the box   To use the PUT and DELETE verbs with the Web API you need to edit  userprofile  documents iisexpress config applicationhost config and add the verbs to the ExtensionlessUrl handler as follows   Change this line    lt add name  ExtensionlessUrl-Integrated-4 0  path      verb  GET HEAD POST DEBUG  type  System Web Handlers TransferRequestHandler  preCondition  integratedMode runtimeVersionv4 0    gt    to    lt add name  ExtensionlessUrl-Integrated-4 0  path      verb  GET HEAD POST DEBUG PUT DELETE  type  System Web Handlers TransferRequestHandler  preCondition  integratedMode runtimeVersionv4 0    gt    In addition to the above you should ensure WebDAV is not interfering with your requests  This can be done by commenting out the following lines from applicationhost config    lt add name  WebDAVModule  image   IIS BIN  webdav dll    gt   lt add name  WebDAVModule    gt    lt add name  WebDAV  path     verb  PROPFIND PROPPATCH MKCOL PUT COPY DELETE MOVE LOCK UNLOCK  modules  WebDAVModule  resourceType  Unspecified  requireAccess  None    gt    Also be aware that the default Web API convention is that your method name should be the same as the invoked HTTP verb  For example if you re sending an HTTP delete request your method  by default  should be named Delete

You can convert your Delete method as POST as     HttpPost   public void Delete YourDomainModel itemToDelete

Besides all above solutions  check if you have the  id  or any custom defined parameter in the DELETE method is matching the route config   public void Delete int id       some code here     If you hit with repeated 405 errors better reset the method signature to default as above and try    The route config by default will look for id in the URL  So the parameter name id is important here unless you change the route config under App Start folder   You may change the data type of the id though    For example the below method should work just fine   public void Delete string id       some code here     Note  Also ensure that you pass the data over the url not the data method that will carry the payload as body content   DELETE http    url   action   id    Example   DELETE http   localhost item 1   Hope it helps

Just a quick update for anyone else who might run into this issue  As of today  changing the  userprofile  documents iisexpress config applicationhost config does NOT work any longer  this was working fine until now  not sure if this is due to a Windows update   After hours of frustration  I changed the web config to add these handlers to system webserver to get it to work    lt handlers gt           lt remove name  ExtensionlessUrlHandler-ISAPI-4 0 32bit    gt           lt remove name  ExtensionlessUrlHandler-ISAPI-4 0 64bit    gt           lt remove name  ExtensionlessUrlHandler-Integrated-4 0    gt            lt add name  ExtensionlessUrlHandler-ISAPI-4 0 32bit  path      verb  GET HEAD POST DEBUG PUT DELETE PATCH OPTIONS  modules  IsapiModule  scriptProcessor   windir  Microsoft NET Framework v4 0 30319 aspnet isapi dll  preCondition  classicMode runtimeVersionv4 0 bitness32  responseBufferLimit  0    gt           lt add name  ExtensionlessUrlHandler-ISAPI-4 0 64bit  path      verb  GET HEAD POST DEBUG PUT DELETE PATCH OPTIONS  modules  IsapiModule  scriptProcessor   windir  Microsoft NET Framework64 v4 0 30319 aspnet isapi dll  preCondition  classicMode runtimeVersionv4 0 bitness64  responseBufferLimit  0    gt           lt add name  ExtensionlessUrlHandler-Integrated-4 0  path      verb  GET HEAD POST DEBUG PUT DELETE PATCH OPTIONS  type  System Web Handlers TransferRequestHandler  preCondition  integratedMode runtimeVersionv4 0    gt       lt  handlers gt

Remove the WebDAV works perfectly for my case    lt modules gt     lt remove name  WebDAVModule   gt   lt  modules gt   lt handlers gt     lt remove name  WebDAV    gt     lt remove name  ExtensionlessUrlHandler-Integrated-4 0    gt     lt add name  ExtensionlessUrlHandler-Integrated-4 0  path      verb  GET HEAD POST DEBUG PUT DELETE PATCH OPTIONS          type  System Web Handlers TransferRequestHandler  preCondition  integratedMode runtimeVersionv4 0    gt   lt  handlers gt    it always better to solve the problem through the web config instead of going to fix it through the iis or machine config to grantee it wouldn t happen if the app hosted at another machine

The another reason can be the following   I changed my Url for Web Api method according to this answer   Url Action  MyAction    MyApiCtrl   new   httproute           But this method creates link like    api MyApiCtrl action MyAction   This works correctly with GET and POST requests but not with PUT or DELETE    So I just replaced it with    api MyApiCtrl   and it fixed the problem

I have faced the same issue with you  then solved it   Here are solutions  I wish it maybe can help  First  In the IIS modules Configuration  loop up the WebDAVModule  if your web server has it  then remove it   Second   In the IIS handler mappings configuration  you can see the list of enabling handler  to choose the PHP item  edit it  on the edit page  click request restrictions button  then select the verbs tab in the modal  in the specify the verbs to be handle label  check the all verbs radio  then click ok  you also maybe see a warning  it shows us that use double quotation marks to PHP-CGI execution  then do it  if done it  then restart IIS server  it will be ok

For PHP  it was simply    Open IIS Go to Handler Mappings click edit on php5 6 x or php7 0 x click  request restrictions  under the verbs tab  select  one of the following verbs  and add  GET HEAD POST PUT PATCH DELETE OPTIONS    I imagine this will work with other handlers too

After endless searching and trying the already supplied answers  adding the PUT DELETE verbs and remove WEBdav  it just didn t work   I went to IIS logging settings    View Log Files  In my case W3SVC4 was the folder with the latest date  opened the folder  looked up the latest log file and saw this entry  GET  Rejected-By-UrlScan   MYDOMAIN API ApiName UpdateMETHOD  The Update method was listed with verb GET  weird right  So I Googled for Rejected-By-UrlScan and found this link  UrlScan Broke My Blog    I went to here   windir  system32 inetsrv urlscan UrlScan ini  Basically  the UrlScan blocked PUT and DELETE verbs  I opened this INI file  added the PUT and DELETE to the AllowVerbs and removed them from the DenyVerbs listings  I saved the INI file and it worked  So for me these steps were necessary next to the ExtensionlessUrlHandler hints   Windows Webserver 2008 R2  64 bit   IIS 7 5  I m using this in combination with DotNetNuke  DNN  WebAPI  ASP Net 4 0 My update method    HttpPut   DnnAuthorize StaticRoles    MyRoleNames    public HttpResponseMessage UpdateMETHOD DTO MyObject myData
