Xamarin Forms Network Requests Automatic Instrumentation and Tracking

Osama_Abbas — Thu, 04 Apr 2024 13:21:37 GMT

I am trying to instrument a Xamarin Forms app with the following configuration:.

var config = AppDynamics.Agent.AgentConfiguration.Create("<EUM_APP_KEY>");
config.CollectorURL = "http://<IP_Address>:7001";
config.CrashReportingEnabled = true;
config.ScreenshotsEnabled = true;
config.LoggingLevel = AppDynamics.Agent.LoggingLevel.All;
AppDynamics.Agent.Instrumentation.EnableAggregateExceptionHandling = true;
AppDynamics.Agent.Instrumentation.InitWithConfiguration(config);

In the documentation, it is stated that: The Xamarin Agent does not support automatic instrumentation for network requests made with any library. You will need to manually instrument HTTP network requests regardless of what library is used. Mobile RUM Supported Environments (appdynamics.com)

Yet, in these links Customize the Xamarin Instrumentation (appdynamics.com) and Instrument Xamarin Applications (appdynamics.com) I see that I can use AppDynamics.Agent.AutoInstrument.Fody package to automatically instrument the network requests.

I tried to follow the approach of automatic instrumentation using both AppDynamics.Agent and AppDynamics.Agent.AutoInstrument.Fody packages as per the docs, but I get the below error when building the project:

MSBUILD : error : Fody: An unhandled exception occurred:

Any help please?

Thank you
