Is routes case-sensitive in Web API OData Service using ODataController?

Question

i followed this to learn how ODataController works, everything is OK but when i changed the request uri
from

"localhost:49292/odata/Employees" //result: 200

to

"localhost:49292/odata/employees" //result: 404

to say one word: "odata" or "Odata" and "Employee" are all ok, but lowercase "employee" return 404. any explanation about this. Moreover, the routes in asp.net mvc is not case-sensitive afaik.

Answer 1

how about including a Route attribute and direct it to lower case. for Upper case web api will take care about it

[Route("odata/employees")]

add this on the top of the controller

if odata is common for every action then you can include [RoutePrefix] attribute

Answer 2

You can manually do it using the ODataModelBuilder instead of the ODataConventionModelBuilder

e.g

        var builder = new ODataModelBuilder();
        builder.EntitySet<Order>("Employees");
        builder.EntitySet<Order>("employees"); 

this will work but your metadata will show 2 entity sets:

{
@odata.context: "http://localhost:62881/$metadata",
value: [
{
name: "Employees",
kind: "EntitySet",
url: "Employees"
},
{
name: "employees",
kind: "EntitySet",
url: "employees"
}
]
}

Answer 3

lowercase "employee" return 404.

I hope you probably didn't have the typo like that.

AFAIK, there is a case limitation on filter and properties. (You can vote there https://aspnetwebstack.codeplex.com/workitem/366 ) but not sure about the controller name..

You can create the REST server using web api without having oData as well..
