How to set ConnectionString using ILogger?

[TimothyMothra]

We have an internal customer using ILogger, and they need to set the ConnectionString but it appears that we don't expose that in the ILogger SDK.

We have a constructor overload that would permit this, but it's currently set to private.

ApplicationInsights-dotnet/LOGGING/src/ILogger/ApplicationInsightsLoggingBuilderExtensions.cs

Lines 90 to 100 in a26a43f

	/// <summary>
	/// Adds an ApplicationInsights logger named 'ApplicationInsights' to the factory.
	/// </summary>
	/// <param name="builder">The <see cref="ILoggingBuilder"/> to use.</param>
	/// <param name="configureTelemetryConfiguration">Action to configure telemetry configuration.</param>
	/// <param name="configureApplicationInsightsLoggerOptions">Action to configure ApplicationInsights logger.</param>
	private static ILoggingBuilder AddApplicationInsights(
	this ILoggingBuilder builder,
	Action<TelemetryConfiguration> configureTelemetryConfiguration,
	Action<ApplicationInsightsLoggerOptions> configureApplicationInsightsLoggerOptions)
	{

I propose we set this to public to unblock this customer.

@cijothomas do you know of any workarounds?

If using, DI then the following should work as shown in doc example
https://docs.microsoft.com/en-us/azure/azure-monitor/app/ilogger#console-application

services.Configure<TelemetryConfiguration>(
            (config) =>
            {
                config.ConnectionString  = "";
            }
        );

There is an active PR #1643 to make this method as public.

Thanks Raj, We may need to fork this PR and finish it ourselves.

Hi I would appreciate if this change will be merged. Azure recommend to use connection string instead of Instrumentation keys. But it is impossible to do when I need to configure Logger in ASP.Net core Program.cs

Agree. this should be prioritized for the coming release.
