So I have 2 web services – one is a web-api service and the other is some Frankenstein. When a CORS request comes over to the server it comes with the “OPTIONS” HTTP method, so I’m guessing there is an “options” attribute you can add to customize the request for a specific method… Not sure why you would do that though.
Here are the notes I’ve collected from the process of adding support to both services:
Web API steps
My big hangup is doing this in visual studio 2012 – it doesn’t appear to be made to work out of the box in vs2012…
– Include System.Web.Cors.dll and System.Web.Http.Cors.dll – had to download the nuget package Microsoft.AspNet.WebApi.Cors.
– Enable CORS in the WebApiConfig.Register – you can then use the [EnableCors] attribute. However the example in the codeplex example appears to be bad — You can’t instantiate a EnableCorsAttribute object without parameters…
– To load settings from your config, you have to implement an ICorsPolicyProvider class
– Examples in the second link show how to implement it as a custom attribute
– Had to add a dependent section to the web.config:
<dependentAssembly> <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="22.214.171.124-126.96.36.199" newVersion="188.8.131.52" /> </dependentAssembly>
– Had to follow the nuget update steps in: http://stackoverflow.com/questions/18347290/webapi-odata-5-0-beta-accessing-globalconfiguration-throws-security-error
– Added one more dependent section to the web.config
<dependentAssembly> <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="184.108.40.206-220.127.116.11" newVersion="18.104.22.168" /> </dependentAssembly>
