This project illustrates a simple approach towards ABP VNEXT working with ODATA. I think it is still a side-by-side implementation.
ABP VNEXT project does not provide a nuget package supporting OData. You should setup everything by yourself. Base ABP VNEXT project is the tutorial project(generated by abp cli) in abp.io
ABP VNEXT uses auto-generated WebAPI controller mechanism. Hense I disable the RemoteService and write a custom controller to configure OData and route it manually.
Set TodoApp.HttpApi.Api.Host as starting project and run.
GET /api/app/Todo to start an OData Query. e.g. /api/app/Todo?$count=true.
Visit /api/app/$metadata#Todo to get edm schema of the DTO.
This project is just a demo. It is not well designed in OData part. Never use it in production.
I will write posts on this approach.
There are several posts(Chinese) about OData which might be helpful for leveraging OData.
