How to enable CORS in .NET Core or Framework when AQB service is on a different host/port than the webserver?

To enable CORS for Active Query Builder in a .NET Core project, add the following line as the first line to the Configure method in the Startup.cs file:

  app.UseCors(
  	b => b.AllowAnyHeader().AllowAnyMethod().AllowAnyOrigin() 
  );

To enable CORS in a .NET Framework project, add the "Access-Control-Allow-Origin" header via the web.config file as follows:

<system.webServer>
  ...
  <httpProtocol>
    <customHeaders>
      <clear />
      <add name="Access-Control-Allow-Origin" value="*" />
    </customHeaders>
  </httpProtocol>
  ...
</system.webServer>
