  5. Backend Call // REST API Call -> «Add REST Client»

    var url = $"{endpointUri}/Game/?countryCode={code}"; var client = new WmAPI.WmAPIClient(url); Game[] result = client.GetAll(); <!-- TypeScript --> -> Convert Swagger to TypeScript Class const url = `${endpointUri}/Game/?countryCode=${code}`; return this.http.get<Game[]>(url);
  6. Data Binding // XAML <Label Content="{Binding /MatchInfo1}"/> <ListView ItemsSource="{Binding}" DisplayMemberPath="Description"
