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("testcontrollers");

return builder.GetEdmModel();

}

However when accessing odata points I always get 404 error.

Try to configure as shown below
public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();
        services.AddOData();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseHttpsRedirection();

        app.UseRouting();

        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
            endpoints.Select().Filter().OrderBy().Count().MaxTop(10);
            endpoints.MapODataRoute("odata", "odata", GetEdmModel());
        });
    }

    private IEdmModel GetEdmModel()
    {
        var odataBuilder = new ODataConventionModelBuilder();
        odataBuilder.EntitySet("Test");

        return odataBuilder.GetEdmModel();
    }
}
