base on ASP.NET Core OData: A server library built upon ODataLib and ASP.NET Core # ASP.NET Core OData --- Component | Build | Status --------|--------- |--------- ASP.NET Core OData|Rolling | [](https://identitydivision.visualstudio.com/OData/_build/latest?definitionId=2403&repoName=OData%2FAspNetCoreOData&branchName=main) ASP.NET Core OData|Nightly | [](https://identitydivision.visualstudio.com/OData/_build/latest?definitionId=2404&repoName=OData%2FAspNetCoreOData&branchName=main) .NET Foundation|Release|[](https://dev.azure.com/dotnet/OData/_apis/build/status/AspNetCoreOData/AspNetCoreOData-main-Yaml-release?branchName=main) A server-side OData library for ASP.NET Core. Use this project to create OData services on top of ASP.NET Core and ODataLib. It provides routing, query handling, model building, formatters and more. Quick links - NuGet: https://www.nuget.org/packages/Microsoft.AspNetCore.OData/ - Documentation: https://learn.microsoft.com/odata/webapi-8/ - Samples: ./sample - Source: https://github.com/OData/AspNetCoreOData --- ## Quick start Using .NET CLI: ```bash dotnet add package Microsoft.AspNetCore.OData ``` ### Example - Configure OData This simple example shows how to register OData and expose an entity set named `Products`. ```csharp using Microsoft.AspNetCore.Builder; using Microsoft.Extensions.Hosting; using Microsoft.AspNetCore.OData; using Microsoft.OData.Edm; using Microsoft.OData.ModelBuilder; var builder = WebApplication.CreateBuilder(args); // Register controllers and OData builder.Services .AddControllers() .AddOData(options => options.AddRouteComponents("odata", GetEdmModel()) .Select().Filter().OrderBy().Expand().Count().SetMaxTop(null)); var app = builder.Build(); if (app.Environment.IsDevelopment()) { // Helpful only during development app.UseODataRouteDebug(); } app.UseRouting(); app.MapControllers(); app.Run(); static IEdmModel GetEdmModel() { var builder = new ODataConventionModelBuilder(); builder.EntitySet<Product>("Products"); return builder.GetEdmModel(); } public class Product { public int Id { get; set; } public string Name { get; set; } public decimal Price { get; set; } } ``` ### Example controller (ODataController) ```csharp using Microsoft.AspNetCore.Mvc; using Microsoft.AspNetCore.OData.Routing.Controllers; using Microsoft.AspNetCore.OData.Query; public class ProductsController : ODataController { private static List<Product> products = new List<Product> { new Product { Id = 1, Name = "Product 1", Price = 10.0M }, new Product { Id = 2, Name = "Product 2", Price = 20.0M } }; [EnableQuery] public IActionResult Get() { return Ok(products); } [EnableQuery] public IActionResult Get(int key) { var product = products.FirstOrDefault(p => p.Id == key); if (product == null) { return NotFound(); } return Ok(product); } } ``` For more examples (including Minimal API samples) see the `sample` folder in this repository. --- ## Samples This repository includes a set of example applications under the `sample` directory. Notable samples: - `sample/ODataRoutingSample` — a full Web API sample showing routing, $metadata and Swagger integration. - `sample/ODataMiniApi` — examples of Minimal API style OData endpoints. Run a sample: ```bash cd sample/ODataRoutingSample dotnet run ``` Then browse to `http://localhost:5000/odata/Products` (port may vary) to inspect the service. --- ## Github Repository This is the official ASP.NET Core OData repository.

Building and Testing in Visual Studio Visual Studio 2022 is required to build the source project in order to support the `DateOnly` and `TimeOnly` types, which were introduced in .NET 6. ### 2. One-click build and test script in command line Coming soon. ### 3. Debug The symbol package is uploaded to nuget symbol server. It supports source link debug. Remember to check `Enable Source Link support` if you debug using Visual Studio. ### 4.
