How do you enable cross-origin requests (CORS) in ASP.NET Core MVC

Question

I\'d like to enable CORS on an API built with ASP.NET Core MVC, but all the current documents refer to earlier versions of that framework.

Answer 1

cs1929 the method services.ConfigureCors(...) does no more exist. It is combined to AddCors:

services.AddCors(options => 
    options.AddPolicy("AllowAllOrigins", builder => builder.AllowAnyOrigin()));
