Today, I will write about PUT, POST and DELETE verbs on the web application in IIS. And this is the error:

<h2>405 - HTTP verb used to access this page is not allowed.</h2>
<h3>The page you are looking for cannot be displayed because an invalid method (HTTP verb) was used to attempt access

After some troubleshooting the error was isolated to the actual fact that WebDav was put in on the server and was intercepting those requests for its own service use.
Rather than removing WebDav from the server, we tend to went searching for another answer. thankfully somebody on Twitter understood the problem and gave an example of changes to create to the client’s web.config get in order to disable (remove) the WebDav module for simply that specific website while not requiring any manual body actions on the server.

The code updates to create to your web.config file to resolve this error are:
      <remove name="WebDAV" />
      <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,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
      <remove name="WebDAVModule" />
