How to enable CORS in ASP.NET Core

Question

I am trying to enable cross origin resources sharing on my ASP.NET Core Web API, but I am stuck.

The EnableCors attribute accepts policyName

Answer 1

Based on Henk's answer I have been able to come up with the specific domain, the method I want to allow and also the header I want to enable CORS for:

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(options =>
         options.AddPolicy("AllowSpecific", p => p.WithOrigins("http://localhost:1233")
                                                   .WithMethods("GET")
                                                   .WithHeaders("name")));
    services.AddMvc();
}

usage:

[EnableCors("AllowSpecific")]
