There are two types how to enable CORS (Cross Origin Resource
Sharing), one simply add Access-Control-Allow-Origin header value for each request that requires
CORS support. Five the value of this header is “*” to grant access from any
domain.
HttpContext.Response.AppendHeader("Access-Control-Allow-Origin", "*");
Or you simply
add in web.config to access in full application like this.
<system.webServer>
<httpProtocol>
<customHeaders>
<clear />
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
