Error: ConnectFailure (Connection refused) - ios

I have the xamarin.forms application for which i am trying to connect localhost from PC to Iphone simulator in mac,Iam using the Ip address for connecting,
private string Uri = "http://192.168.0.16:62271/";//Windows Ip address:localhost port number
private string GetDishesUrl = "api/DishDetails/GetDishDetails?id=5";
try{
var httpClient = new HttpClient();
httpClient.BaseAddress = new Uri(Uri);
var response = await httpClient.GetAsync(new Uri(Uri + GetDishesUrl));
var stringAsync = await response.Content.ReadAsStringAsync();
if (response.IsSuccessStatusCode)
{
var responseJson = stringAsync;
return JsonConvert.DeserializeObject<List<DishDetails>>(responseJson);
}
}
catch(Exception ex)
{
}
Here iam getting following Exception:

Reflection doesn't work only with webassembly

On https://fable.io/ it's working but it's not working with https://tryfsharp.fsbolero.io/
The first run the code on a server. The second run the code with webassembly on the computer calling this it.

does the problem come from webassembly and why?
As #JL0PD correctly guessed in their comment, this is because Bolero's tryfsharp runs an older compiler that doesn't support nameof.
Updating it has been on my to-do list for ever, but there have been non-trivial changes both in Blazor and in the F# compiler service since the latest release of tryfsharp.bolero.

Thanks for the help

can any one help me with using IdentityServer3 to use MVCViewService with Aspidentity

I am using IdentityServer3 samples to make a MVCView Service to work with asp.net identity. The samples work individually (i.e. plain idserver using asp.net identity Or MVC View Service showing custom login/logout pages).
However, when I try to combine both I get below error
Unhandled exception accessing: /core/connect/authorize

Error: NameResolutionFailure means that your code was unable to resolve a domain name -- likely the domain name you use in your StripeClient.CreateToken method.
By the way, the rest of the code has no chance of working. Even if you succeed in creating a token, POSTing a token to https://stripe.com/token will result in a 404 error since there is nothing at that URL.
I recommend you take some time to browse through Stripe's documentation, and in particular how to create charges using tokens.
