CORS in .NET Core

Question

I am trying to enable CORS in .NET Core in this way:

    public IConfigurationRoot Configuration { get; }

    public void ConfigureServices(IServiceCollecti         


        

Answer 1

this is actually is a bug in dotnet core.

try to add cors policy right in the "Configure" method.

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        app.UseRouting();
        app.UseCors(option =>
            option.AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                );
    }
