Note that Asp.Net developers can build OData V4 services using the higher-level OData V4 WebAPI libraries available at: https://www.nuget.org/packages/Microsoft.AspNet.OData/ with support documentation available at: https://odata.github.io/WebApi/. Classes to serialize, deserialize and validate OData payloads. Enables construction of OData producers and consumers.
