Have you seen this package Polly<\/a> <\/p>\n

\n

Polly is a .NET 3.5 \/ 4.0 \/ 4.5 \/ PCL library that allows developers to express transient exception handling policies such as Retry, Retry Forever, Wait and Retry or Circuit Breaker in a fluent manner.<\/p>\n<\/blockquote>\n

You could use it to catch the WebException<\/code> then retry or switch out the URL. <\/p>\n

Here is an example from the blog post below:<\/p>\n

\n

In this example, we will try connecting to our service five times, with an exponential wait of 2, 4, 8, 16, and 32 seconds between tries. This should give the device a chance to reestablish its network connection and continue the request to the api.<\/p>\n<\/blockquote>\n

conferences = await Policy  \n  .Handle<WebException>()\n  .WaitAndRetry\n  (\n    retryCount:5, \n    sleepDurationProvider: retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt))\n  )\n  .ExecuteAsync(async () => await getConferencesTask);\n<\/code><\/pre>\n
Here is a blog post talking about Resilient network services with mobile Xamarin apps<\/a> <\/p>\n<\/p><\/div>\n
