According to your description, I guess the reason why you face the error target not found is you set the wrong InstrumentationKey.

I suggest you could recheck the InstrumentationKey, which could found in the AI's overview like this:

Then you could use below code to test it.

Install the Microsoft.ApplicationInsights.NLogTarget package

        var config = new LoggingConfiguration();

        ApplicationInsightsTarget target = new ApplicationInsightsTarget();

        target.InstrumentationKey = "key";
        LoggingRule rule = new LoggingRule("*", NLog.LogLevel.Trace, target);
        config.LoggingRules.Add(rule);

        LogManager.Configuration = config;

        Logger logger = LogManager.GetLogger("Example");

        logger.Trace("trace log message");

        Console.Read();

At last, you could find the record in the search feature.

Update:

Two application use the same AI:
