If it is not possible to update to Xamarin.iOS 9.8 (or higher), the work around is to manually edit the. This error is caused by the introduction of the MtouchTlsProvider setting to the project file in Xamarin.iOS 9.8. The following screenshot is a example of the error message that may be displayed in this scenario: These changes may cause problems when the project is opened with older versions of Xamarin.iOS. csproj file for a Xamarin.iOS application. Xamarin.iOS 9.8 introduced some new settings contained the. Project failed to load with error 'Requested value AppleTLS wasn't found' This section will cover known issues with TLS support in Xamarin.iOS. To find out more about ATS, please see our App Transport Security guide. If your connections do not meet these requirements, they will fail with an exception.Д«ased on your HttpClient Stack and SSL/TLS Implementation selections, you may need to make modifications to your app to work correctly with ATS. Since ATS is enabled by default in apps built for iOS 9, tvOS 9 and OS X 10.11 (El Capitan) and newer, all connections using NSUrlConnection, CFUrl or NSUrlSession will be subject to ATS security requirements. ATS ensures that all internet communications conform to secure connection best practices, thereby preventing accidental disclosure of sensitive information either directly through your app or a library that it is consuming. To target macOS 10.7 or macOS 10.8, use Xamarin.Mac 4.6 orДЄpple's App Transport Security (ATS) enforces secure connections between internet resources (such as the app's back-end server) and your app. These older macOS versions lack sufficient TLS infrastructure to support Previous versions of Xamarin.Mac supported macOS 10.7 or higher, but The upcoming Xamarin.Mac 4.8 release will only support macOS 10.9 or higher. Apple's native implementation supports TLS 1.2. Xamarin.iOS, OS or Xamarin.Mac's implementation will call Apple's native SSL/TLS implementation instead of using the managed implementation provided by Mono. SSL (Secure Socket Layer) and its successor, TLS (Transport Layer Security), provide support for HTTP and other network connections via. This makes it possible to use a different HttpMessageHandler from what is declared in the Project Options dialog. HttpClient client = new HttpClient(new NSUrlSessionHandler()) This will create an HttpClient that explicitly uses NSUrlSessionHandler HttpClient client = new HttpClient(new CFNetworkHandler()) This will create an HttpClient that explicitly uses the CFNetworkHandler set in the Project Options for the project.

In addition to the project-wide configuration shown above, you can also instantiate an HttpClient and inject the desired HttpMessageHandler through the constructor, as demonstrated in these code snippets: // This will use the default message handler for the application as Programmatically setting the HttpMessageHandler

It requires more managed code, thus creating a larger app distributable.

It typically much slower at things like encryption than the native APIs.

It may not be able to connect to secure web servers or cloud services in the future.

It is not fully integrated with the Apple OSes and is limited to TLS 1.0.

It has the most compatible feature set with Microsoft.

The Managed handler is the fully managed HttpClient handler that has been shipped with previous version of Xamarin.

Support for newer standards such as TLS 1.2.

The CFNetwork-based handler is based on the native CFNetwork framework available in iOS 6 and newer.

Some HttpClient features/options are not available.

Support for the latest standards such as TLS 1.2.

It uses native APIs for better performance and smaller executable size.

The NSURLSession-based handler is based on the native NSURLSession framework available in iOS 7 and newer. For TLS 1.2 support the NSUrlSession option is recommended.
