Is there an existing issue for this?

Describe the bug

We have an endpoints already clients are using it currently and we don't want to change them. and could not add multiple endpoints for a entity with different prefix in path.

i have attached a sample project to reproduce the scenario: https://github.com/padhumailin/ODataRouteComponent

for example our existing endpoints : http://localhost:9542/general/api/devices http://localhost:9542/private/api/devices

http://localhost:9542/general/api/customers/{Country}/{type} http://localhost:9542/private/api/customers/{Country}/{type}

following error occurs when register the multiple endpoints for same entity in start up: Error : AmbiguousMatchException: The request matched multiple endpoints. Matches: ODataRouteComponent.Controllers.DevicesController.GetPublicDevices (ODataRouteComponent) Microsoft.AspNetCore.OData.Routing.Controllers.MetadataController.GetServiceDocument (Microsoft.AspNetCore.OData)

i arrived a workaround for this issue :

1. These endpoints not registered in startup, but register without prefix
2. Redirect to a another action method where prefix is send as route parameter

redirected endpoints as follows: http://localhost:9542/api/devices/{accessType} -> prefix 'general' is send as route parameter {accessType} http://localhost:9542/api/customers/{accessType}/{Country}/{type}

My Question : Is this right way of implementation? or have any better solution

Another Issue :

For route parameters, DynamicSegmentTemplate is applied in odata routing convention. this causes @odata.type in response and @odata.context metadata url not working its returning 404

is there any way hide this from response. i tried with custom serialization but not works and any solution for @odata.context to work.

Another Issue : using KeySegmentTemplate instead of DynamicSegmentTemplate, causing issue in open api swagger , the route parameters are shown as key value pair. and this occurs only for muttiple routeparams.

Odata V8 EF core 6 Net core 6

Expected Behavior

No response

for swagger url issue (), tried routeOptions.UrlKeyDelimiter = ODataUrlKeyDelimiter.Slash; in ConfigureServices method startup.cs but not working.

for Another Issue 3 mentioned above, i have tried routeOptions.UrlKeyDelimiter = ODataUrlKeyDelimiter.Slash; in ConfigureServices, but not working
