Creating a .NET 5 logging class library

We will create a class library (DLL) that will support Application Insights logging and can be extended to support logging to other sources if needed. Perform the following steps for this:

  1. Create a new .NET 5 class library with the name Logger.
  2. Install the Microsoft.ApplicationInsights package.
  3. Create a new class called ICustomLogger.cs and add the following code:
    using System;
    using System.Collections.Generic;
    namespace Logger
    {
        public interface ICustomLogger
        {
            void Dependency(string dependencyTypeName, 
             string dependencyName, string data, 
             DateTimeOffset startTime, TimeSpan duration,
