Documentation:

For comprehensive documentation, please refer to the following links:

• ASP.NET Core OData Overview
• Getting Started
• Fundamentals Overview
• Tutorials
• OData Dev Blogs
• OData.org

Example:

• ODataRoutingSample: ASP.NET Core OData sample project in this repo.

  • ~/$odata gives a static routing table page of the service

  • ~/swagger gives a swagger/openapi page

  • Append ~/$openapi to each route gives a raw openapi OData page, for example, ~/v1/$openapi

  Please go to sample folder see more samples.

Solution:

• AspNetCoreOData.sln:

  • Includes Microsoft.AspNetCore.OData project, Unit Test, E2E Test & Samples

• AspNetCoreOData.NewtonsoftJson.sln

  • Includes Microsoft.AspNetCore.OData.NewtonsoftJson project, Unit Test, E2E Test & Samples

2. Basic Usage

Microsoft.AspNetCore.OData Package Installation

Using .NET CLI:

dotnet add package Microsoft.AspNetCore.OData

Using Package Manager:

Install-Package Microsoft.AspNetCore.OData

In the ASP.NET Core Web Application project, update your Startup.cs as below:

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContext<BookStoreContext>(opt => opt.UseInMemoryDatabase("BookLists"));
        services.AddControllers().AddOData(opt => opt.AddRouteComponents("odata", GetEdmModel()));
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // Send "~/$odata" to debug routing if enable the following middleware
        // app.UseODataRouteDebug();

        app.UseRouting();
        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }

    private static IEdmModel GetEdmModel()
    {
        // …
    }
}

If you work with Program.cs, update as below. Refer to the Getting Started Guide.

// using statements

var builder = WebApplication.CreateBuilder(args);

var modelBuilder = new ODataConventionModelBuilder();
modelBuilder.EntityType<Order>();
modelBuilder.EntitySet<Customer>("Customers");

builder.Services.AddControllers().AddOData(
    options => options.Select().Filter().OrderBy().Expand().Count().SetMaxTop(null).AddRouteComponents(
        "odata",
        GetEdmModel()));

var app = builder.Build();

app.UseRouting();

app.MapControllers();

app.Run();

static IEdmModel GetEdmModel()
{
    // …
}

That's it.

3. Building, Testing, Debugging and Release

3.1 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.

3.2 One-click build and test script in command line

Coming soon.

3.3 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.
