Overview of this book

The .NET Standard is a standard that represents a set of APIs that all .NET platforms have to implement, making it easy for developers to access and use one common library for their development needs. This book begins with a quick refresher, helping you understand the mechanics of the new standard and offering insight into how it works. You’ll explore the core library concepts, such as working with collections, configurations, I/O, security, and multithreading. You’ll explore the iOS and Android libraries of Xamarin and we’ll guide you through creating a .NET Standard 2.0 library, which you’ll use with both Android and iOS applications. In the final chapters, you’ll learn the various debugging and diagnostics tools to deliver quality libraries and create a NuGet package of the .NET Standard 2.0 library. By the end of this book, you’ll be able to expand your current workflow to various .NET flavors and have the essential skills to create a .NET Standard 2.0 library from scratch to package and deliver it to the world.

Informing the end user – Exception handling and error messages

In this recipe, we will be looking at exception handling inside a .NET class library. We will be reusing the same library created in the first recipe of this chapter.

Getting ready

Make sure you have completed the two recipes from this chapter. Open the solution and perform a quick build to check that everything is fine and compiles well.

How to do it...

Open Visual Studio 2017.
Now, open the solution from the previous recipe. Click File | Open | Open Project/Solution, or press Ctrl + Shift + O, and select the Chapter10.Logging solution.
Press Ctrl + Shift + B for a quick build to check that everything is fine.

The Solution Explorer should look like this:

Now, double-click on the LoggerDemo.cs label to open the code window.
Scroll down until you reach the WriteLog() method.
Replace the current code with the following:

      try
      {
          if (!File.Exists(logFileName))
          {
              logFile = File.CreateText(logFileName...
