Getting 'Cross-Origin Request Blocked' on a GET request.

In this article, I will explain how to avoid cross-origin error in Web API.

Just add "cors" packages from NuGet package manager and add this code in WebApiConfig.cs file.

using System.Web.Http.Cors;

public static class WebApiConfig
{
        public static void Register(HttpConfiguration config)
        {
            var corsAttr = new EnableCorsAttribute(BusLib.Config.Configuration.CorsOrigin, "*", "*");
            config.EnableCors(corsAttr);
        }
}
