Difficulty: EasyConfigure Application Insights Instrumentation and Telemetry

You are developing a worker utility in C# that processes queue messages. You need to configure Application Insights telemetry programmatically without using dependency injection. Complete the following C# code snippet to initialize the telemetry configuration and apply the connection string. What are the correct API members to write in the blanks?

Answer:TelemetryConfiguration config = TelemetryConfiguration.【CreateDefault】();
config.【ConnectionString】 = "InstrumentationKey=00000000-0000-0000-0000-000000000000;IngestionEndpoint=https://eastus-0.in.applicationinsights.azure.com/";
TelemetryClient client = new TelemetryClient(config);

Answer

Use 'CreateDefault' to instantiate the default configuration and 'ConnectionString' to set the Azure Monitor connection string.
To manually configure telemetry in C#, TelemetryConfiguration.CreateDefault() is invoked to create a configuration instance with default settings. The ConnectionString property is then assigned the connection string of the Application Insights resource. A TelemetryClient is subsequently initialized using this configuration.

Step-by-Step Solution

1
Identify the factory method on TelemetryConfiguration to instantiate the configuration.
TelemetryConfiguration.CreateDefault()
It returns a new TelemetryConfiguration instance pre-configured with standard telemetry initializers and channels.
2
Identify the property of TelemetryConfiguration that holds the ingestion parameters.
ConnectionString
The ConnectionString property replaced the deprecated InstrumentationKey property to route and authenticate telemetry data securely.
