Web Api 2.2 OData V4 Function Routing

Question

I have a Web Api 2.2 project working with OData v4. The normal EntitySet configuration is working as desired with all http verbs. Where I am having a problem is trying to

Answer 1

Please change the element as below, which is the recommended way if there is dot in the request URL:

 <system.webServer>
        <modules runAllManagedModulesForAllRequests="true" />
 </system.webServer>

and if

http://something/odata/Products/ProductService.MostExpensive()

is requested, I can get the data:

{
@odata.context: "http://localhost:14853/odata/$metadata#Edm.Double",
value: 3
}

Answer 2

Then you may try adding the part not replacing them. Mine looks like below and it can work.

<handlers>
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <remove name="OPTIONSVerbHandler" />
  <remove name="TRACEVerbHandler" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
  <clear/>
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="/*"
      verb="*" type="System.Web.Handlers.TransferRequestHandler"
      preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>

Answer 3

I know this question is not recent, but I found another answer that works for me. If you're willing to remove the namespace from the URL, you can use

config.EnableUnqualifiedNameCall(true);

Your URL would then look like this:

http://something/odata/Products/MostExpensive

See http://odata.github.io/WebApi/#06-01-custom-url-parsing. That's available in the Microsoft.AspNet.OData NuGet package.
