How to enable PUT on IIS 8 (Win Server 2012) on Web API app

Question

I am running a Web API app fine locally. When I deploy it to Windows Server 2012 I can GET fine - but when I try and PUT I get a 405.

I have seen many articles on this - but none of them help.

All I want to do is add something to the Web.Config (on a per app level) that enables PUT. Why is this so hard?

Example post: ASP.NET Web API - PUT & DELETE Verbs Not Allowed - IIS 8

What I added to web config:

<system.web>
<webServices>
  <protocols>
    <add name="HttpGet"/>
    <add name="HttpPost"/>
  </protocols>
</webServices>
</system.web>


<system.webserver>
<httpProtocol>
  <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*" />
    <add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE" />
    <add name="Access-Control-Allow-Headers" value="Content-Type" />
  </customHeaders>
</httpProtocol>
<modules runAllManagedModulesForAllRequests="false">
  <remove name="WebDAVModule" />
</modules>

<validation validateIntegratedModeConfiguration="false" />
<handlers>
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <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" />
  <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" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webserver>

I still get a 405.

How can I get PUT to work? thx.

I finally got it to work by uninstalling WebDAV from the server entirely.

No need to uninstall you have removed WebDAVModule but you missed to remove the WebDEV handler in handlers section like this <handlers><remove name="WebDAV"/></handlers>

Actually, I forgot to put it in my code above - but that was in there and it still required me to uninstall WebDAV to get the site working. – niico Mar 24 '17 at 13:42
