I want to create an OData service, which I will later on run on a Kubernetes cluster.
I use the Nuget Package Microsoft.AspNetCore.OData 7.4.1 and Microsoft.EntityFrameworkCore 3.4.1 in my project.
I'm struggling to find a good sample on how to create this service in .net Core (master detail, table with multiple lookup fields) so Radzen can consume it in the same way like it can use SQL connections.
Radzen itself can generate a OData service for you. Create a Blazor WebAssembly application and use your database as a datasource. Radzen will generate a OData service in the server directory.
You can also look for a tutorial online. For example this or this.
