[0:] An error occurred: 'Operation is not supported on this platform.'. Callstack: ' at System.Net.Http.NSUrlSessionHandler.set_Proxy(IWebProxy value)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

You need to at least provide your code and the version of RestSharp.

Hi @alexeyzimarev, the issue is not just maui related. It is net6-ios related. The problem is that setting the proxy on a
NSUrlSessionHandler causes a PlatformNotSupportedException

The Code looks like
var client = new RestClient("test")

and because of
if (handler.SupportsProxy) handler.Proxy = Options.Proxy;
in ConfigureHttpMessageHandler in RestClient it throws the exception.

I'm on Version 108.0.3.
