ASP.NetCore3.1 and OData

Question

I am working with ASP.NET Core3.1 and OData.The sisue I have is as follows:

Startup.cs added:

 public void ConfigureServices(IServiceCollection services)

{ 

  services.AddOData();

}

 

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)

{

 

app.UseEndpoints(endpoints =>

{

endpoints.MapHealthChecks("/health");

endpoints.MapControllers();

endpoints.Select().Filter().OrderBy().Expand().Count().MaxTop(50);

endpoints.MapODataRoute("odata", "odata", GetEdmModel(app.ApplicationServices));

});

} 

 

private IEdmModel GetEdmModel(IServiceProvider serviceProvider)

{

var builder = new ODataConventionModelBuilder(serviceProvider);

builder.EntitySet<TestController>("testcontrollers");

return builder.GetEdmModel();

}

 

However when accessing odata points I always get 404 error.
